Appeal from the United States District Court
for the Southern District of Florida
________________________

(May 20, 2021)

Before WILLIAM PRYOR, Chief Judge, and JORDAN and MARCUS, Circuit
Judges.

JORDAN, Circuit Judge:

The so-called “terrorism bar” in the Immigration and Nationality Act, 8

U.S.C. § 1182(a)(3)(B), identifies three categories, commonly referred to as “tiers,”

of terrorist organizations. Tier I terrorist organizations are those designated by the

Secretary of State in accordance with 8 U.S.C. § 1189. See § 1182(a)(3)(B)(vi)(I).

Tier II terrorist organizations are those designated “by the Secretary of State in

consultation with or upon the request of the Attorney General or the Secretary of

Homeland Security.” § 1182(a)(3)(B)(vi)(II). Tier III terrorist organizations (the

category at issue in this case) are undesignated. See § 1182(a)(3)(B)(vi)(III).

Whether an entity qualifies as a Tier III terrorist organization is therefore determined

on a case-by-case basis. See Uddin v. Att’y. Gen. U.S., 870 F.3d 282, 285 (3d Cir.

2017). Membership in, or the knowing provision of material support to, a Tier I,

Tier II, or Tier III terrorist organization renders an alien inadmissible under the INA.

See § 1182(a)(3)(B). And inadmissibility generally precludes an adjustment of status

2
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 3 of 29

(e.g., to lawful permanent resident). See 8 U.S.C. § 1159(b)(5); 8 C.F.R.

§ 209.2(a)(1)(v).1

After he left Bangladesh, Mazharul Islam obtained asylum in the United

States. He later sought to adjust his status to lawful permanent resident. United

States Citizenship and Immigration Services ruled, however, that he was ineligible

for adjustment of status due to his membership in a Tier III terrorist organization—

the Bangladesh Nationalist Party—and his personal engagement in terrorist activity.

Mr. Islam unsuccessfully challenged USCIS’ decision in the district court. He

now appeals the district court’s grant of summary judgment in favor of the

government. Following a review of the record, and with the benefit of oral argument,

we affirm.

I

We summarize the facts in the light most favorable to Mr. Islam. See

Warshauer v. Solis, 577 F.3d 1330, 1335 (11th Cir. 2009).

A

The Bangladesh Nationalist Party, or BNP, is one of the two largest political

parties in Bangladesh. The other is the Awami League, or AL.

 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 4 of 29

From 1982 to 1991, a military regime governed Bangladesh. Public uprisings

beginning in 1990 led to the fall of the military regime and the restoration of

democracy in 1991. Since then, the BNP and the AL have alternated periods of

government control. Despite their participation in the Bangladeshi democratic

process, both parties have also resorted to violence, corruption, and other illegal

means to obtain, maintain, and consolidate political power.

Mr. Islam is a native and citizen of Bangladesh, and he has been a member of

the BNP or its student organization since 1995. Around that time he started “to get

really active in BNP political activities . . . [including] working with local BNP youth

groups, going to meetings, and passing out BNP flyers.” D.E. 18-6 at 27. When he

began his college studies, he “became even more active than before in BNP politics.”

Id.

After college, Mr. Islam bought a tea shop, which he operated from 2001 to

2011. The tea shop served as a BNP meeting place, and he posted BNP flyers there

and campaigned for BNP political candidates. On August 1, 2011, Mr. Islam became

the publicity secretary for his local BNP chapter and was responsible for putting up

posters advertising BNP events in the local area.

On August 20, 2011, while closing his tea shop for the day, Mr. Islam was

assaulted by a group of AL members. Aware of his involvement with the BNP, the

group beat him with hockey sticks and threw Molotov cocktails at his tea shop.

4
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 5 of 29

Mr. Islam escaped with the help of local villagers, but not before suffering

burns and a broken finger. Because he tried to report the attack to the police, AL

members ransacked his parents’ house and threatened to kill him. As a result, the

family agreed that he should leave the country for his safety, and he departed on

September 7, 2011.

Three months later, Mr. Islam entered the United States without inspection,

crossing the border at Hidalgo, Texas. He was detained by U.S. Border Patrol shortly

thereafter.

An asylum officer conducted a credible fear interview to determine whether

Mr. Islam was eligible to apply for asylum. During the interview, the asylum officer

asked a series of questions related to his background, the reasons he left Bangladesh,

his political affiliations, and his entry into the United States. As relevant here, the

asylum officer asked Mr. Islam if he had ever belonged to a group accused of using

violence. He responded “no.” The asylum officer found that Mr. Islam had

established a credible fear of persecution, and that he did not appear to be subject to

any bars to asylum or withholding of removal.

In August of 2012, Mr. Islam filed an application for asylum with USCIS. He

confirmed that he belonged to the BNP and denied ever ordering, inciting, or

assisting in causing harm to any persons because of their political opinions. He also

5
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 6 of 29

attached an affidavit to his asylum application, in which he detailed his involvement

with the BNP and the reasons he left Bangladesh.

At the asylum hearing, neither the parties nor the immigration judge discussed

whether Mr. Islam was a member of a terrorist organization or had engaged in

terrorist activity. The immigration judge granted asylum to Mr. Islam, and the

government did not appeal.

B

In January of 2015, Mr. Islam filed an application with USCIS to adjust his

status to lawful permanent resident. USCIS sent him a request for evidence, asking

for information about his involvement with the BNP—including whether he had

contributed financially, held official positions, received military-type training, or

participated in armed conflict on its behalf.

Understanding that USCIS’ request evinced a concern with his membership

in the BNP, Mr. Islam responded with three main arguments. First, the doctrine of

issue preclusion barred USCIS from making any finding that would contradict the

immigration judge’s asylum order. Second, USCIS did not have any lawful basis to

find that the BNP met the definition of a Tier III terrorist organization under

§ 1182(a)(3)(B)(vi)(III). Third, the statutory definition of a Tier III terrorist

organization was vague and overbroad, and therefore void.

6
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 7 of 29

USCIS then sent Mr. Islam a notice of intent to deny his application for

adjustment of status. It explained that it was considering denying the application

under § 1182(a)(3)(B), which deems inadmissible (and therefore ineligible for

adjustment) those aliens who have participated in, or have certain connections to

entities or people who participate in, terrorism. Relying on governmental, NGO, and

press reports, and on the account by Mr. Islam of his actions related to his BNP

membership, USCIS was considering finding that he was a member of a Tier III

terrorist organization and that he had himself engaged in terrorist activity. See

§ 1182(a)(3)(B)(i)(I) & (VI).

Mr. Islam replied to the notice with the same arguments he had presented in

his response to the request for evidence. He asserted that none of the evidence cited

in USCIS’ notice credibly demonstrated that the BNP or its leadership had

authorized, condoned, or sanctioned any violence; that the doctrine of issue

preclusion barred USCIS from re-adjudicating whether he was inadmissible under

the terrorism bar, as the issue had already been decided by the immigration judge in

the asylum proceeding; and that the definition of a Tier III terrorist organization in

§ 1182(a)(3)(B)(vi)(III) was vague and overbroad.

USCIS denied Mr. Islam’s application for adjustment of status on two

grounds. USCIS found that Mr. Islam was a member of a Tier III terrorist

7
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 8 of 29

organization, i.e., the BNP. It also found that Mr. Islam had himself engaged in

terrorist activity by providing material support to the BNP. 2

While the administrative process was ongoing, Mr. Islam filed a petition for

a writ of mandamus requesting that the district court compel USCIS to adjudicate

his application for adjustment of status. After USCIS issued its decision, Mr. Islam

filed an amended complaint in the district court, requesting a declaratory judgment

holding (1) that USCIS was barred by the doctrine of issue preclusion from applying

the INA’s terrorism bar to him, (2) that USCIS erred in finding that the BNP was a

Tier III terrorist organization, and (3) that the statutory definition of a Tier III

terrorist organization was vague and overbroad.

The parties subsequently filed cross-motions for summary judgment. The

government sought summary judgment on each count of Mr. Islam’s complaint. A

magistrate judge issued a report recommending that the district court grant the

government’s motion and deny Mr. Islam’s motion. In response, Mr. Islam filed

objections to the report and recommendation.

The district court issued an order adopting and affirming the magistrate

judge’s report and recommendation. The court first rejected the issue preclusion

argument, concluding that whether the terrorism bar applied to Mr. Islam had not

2
We discuss USCIS’ findings in more detail later in the opinion.
8
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 9 of 29

been “actually litigated” in the asylum proceeding. The court also ruled that USCIS’

determination that Mr. Islam was ineligible to adjust his status—due his being a

member of the BNP, a Tier III terrorist organization, and to his provision of material

support to the BNP—was supported by substantial evidence and was not arbitrary

or capricious. Finally, the court held that the definition of a Tier III terrorist

organization was not unconstitutionally vague or overbroad.

II

The INA is a complex statutory scheme, operating through numerous

interlocking, primary, subordinate, and/or cross-referencing sections and

subsections. Due to that nesting-doll structure, we consider it helpful to begin by

identifying the INA provisions that are relevant to Mr. Islam’s case, and explaining

how they correlate and were applied by USCIS.

The INA permits the Secretary of Homeland Security or the Attorney General

to adjust the status of an alien who has been granted asylum to that of lawful

permanent resident, so long as the asylee meets certain requirements. See § 1159(b).

One of those requirements is that the asylee be considered admissible under the INA

at the time of examination for adjustment. See § 1159(b)(5).

Certain classes of aliens are considered inadmissible under the INA. One of

those classes consists of aliens encompassed by the INA’s terrorism bar. See

§ 1182(a)(3)(B). The terrorism bar, for its part, identifies nine categories of aliens

9
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 10 of 29

who fall within its scope. See id. To recap, USCIS determined that Mr. Islam fell

within two of those categories.

First, USCIS found Mr. Islam inadmissible for being a member of a Tier III

terrorist organization. See § 1182(a)(3)(B)(i)(VI). A Tier III terrorist organization is

“an organization . . . that is a group of two or more individuals, whether organized

or not, which engages in, or has a subgroup which engages in [certain activities,

including ‘terrorist activity.’]” § 1182(a)(3)(B)(vi)(III). The INA’s terrorism bar

defines “terrorist activity” as, among other things, any activity that is “unlawful” and

involves the

use of any . . . . explosive, firearm, or other weapon or
dangerous device (other than for mere personal monetary
gain), with intent to endanger, directly or indirectly, the
safety of one or more individuals or to cause substantial
damage to property . . . . [and] [a] threat, attempt, or
conspiracy to do any of the foregoing.

§ 1182(a)(3)(B)(iii)(V)(b) & (VI).

Relying on the evidence cited in its notice of intent to deny, USCIS

determined that over many years BNP members had engaged in frequent and

widespread acts of violence that constituted terrorist activity as defined in

§ 1182(a)(3)(B)(iii)(V)(b) & (VI). USCIS also found that BNP leadership

sometimes participated in or threatened the use of violence. Moreover, USCIS found

that there was no evidence that BNP leadership took steps to prevent BNP members

10
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 11 of 29

from engaging in terrorist activity or routinely sanctioned members for doing so. As

a result, the BNP had at least tacitly authorized its members’ terrorist activity. By

authorizing that terrorist activity, the BNP itself engaged in it, making it a Tier III

terrorist organization. And because Mr. Islam was a member of the BNP, USCIS

concluded that he was ineligible for adjustment of status.

Second, USCIS found Mr. Islam inadmissible for having personally engaged

in terrorist activity. See § 1182(a)(3)(B)(i)(I). As relevant here, under the terrorism

bar a person engages in terrorist activity when “[he] commit[s] an act that [he]

knows, or reasonably should know, affords material support . . . to a [Tier III terrorist

organization], or to any member of such an organization.”

§ 1182(a)(3)(B)(iv)(VI)(dd). USCIS determined that Mr. Islam had provided

material support to the BNP by using his tea shop as a BNP meeting place,

distributing BNP flyers, and putting up posters of local BNP events.

Under § 1159(b)(5), USCIS’ determination that Mr. Islam was inadmissible

under the terrorism bar resulted in his ineligibility for adjustment of status.

III

On appeal, Mr. Islam argues that the district court erred in granting summary

judgment in favor of the government. Our review is, except where noted, plenary.

See Salmeron-Salmeron v. Spivey, 926 F.3d 1283, 1286 (11th Cir. 2019).

11
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 12 of 29

IV

Mr. Islam first argues that issue preclusion barred USCIS from determining

that he was inadmissible under the INA’s terrorism bar. The district court concluded

that this issue had not been “actually litigated” in the asylum proceeding because it

had not been contested, debated, or raised there. As a result, issue preclusion did not

bar USCIS from adjudicating the application of the terrorism bar. We agree with the

district court.

As noted above, we generally review de novo a district court’s grant of

summary judgment. See, e.g., Barnett v. MacArthur, 956 F.3d 1291, 1296 (11th Cir.

2020). But where the summary judgment order addressed issue preclusion, we

review for clear error the court’s factual determination as to whether an issue was

“actually litigated” in a prior proceeding. See Vazquez v. Metropolitan Dade

County, 968 F.2d 1101, 1106 (11th Cir. 1992).

“A final decision by an immigration judge has a preclusive effect on future

litigation and agency decisions.” Amrollah v. Napolitano, 710 F.3d 568, 571 (5th

Cir. 2013). See also Astoria v. Fed. Sav. & Loan Ass’n v. Solimino, 501 U.S. 104,

108 (1991) (“[W]here a common-law principle is well established, as are the rules

of preclusion, the courts may take it as given that Congress has legislated with an

expectation that the principle will apply except when a statutory purpose to the

contrary is evident.”) (citations and internal quotation marks omitted). The federal

12
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 13 of 29

doctrine of issue preclusion “forecloses relitigation of an issue of fact or law that has

been litigated and decided in a prior suit.” CSX Transp., Inc. v. Brotherhood of

Maint. of Way Emps., 327 F.3d 1309, 1317 (11th Cir. 2003) (internal quotation

marks omitted). For federal issue preclusion to bar relitigation of a particular issue,

(1) the relevant issue must be identical to the one involved in the prior proceeding,

(2) the issue must have been actually litigated in the prior proceeding, (3) the

determination of the issue must have been a critical and necessary part of the

judgment in the prior proceeding, and (4) the party against whom the earlier decision

is asserted must have had a full and fair opportunity to litigate the issue in the prior

proceeding. See id.

Mr. Islam argues that whether the BNP is a Tier III terrorist organization—

and thus whether he is a member of, or provided material support to, such an

organization—was actually litigated in the asylum proceeding. In support, he points

to statements he made in his asylum application, affidavit, and credible fear

interview, as well as to the asylum officer’s finding that there did not appear to be a

bar to asylum. According to Mr. Islam, that evidence “amounted to ‘litigation.’”

Appellant’s Br. at 18. We are not persuaded.

A matter is actually litigated for purposes of issue preclusion when it is

“properly raised, by the pleadings or otherwise, and is submitted for determination,

and is determined.” Pleming v. Universal-Rundle Corp., 142 F.3d 1354, 1359 (11th

13
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 14 of 29

Cir. 1998) (quoting Restatement (Second) of Judgments § 27 cmt. d (1982)). Accord

Janjua v. Neufeld, 933 F.3d 1061, 1066 (9th Cir. 2019); Raspanti v. Keaty (In re

Keaty), 397 F.3d 264, 272 (5th Cir. 2005); McLaughlin v. Bradlee, 803 F.2d 1197,

1202 (D.C. Cir. 1986). In analyzing whether Mr. Islam’s inadmissibility under the

terrorism bar was actually litigated in the asylum proceeding, we find the Ninth

Circuit’s reasoning in Janjua persuasive.

In Janjua, an alien sought asylum due to persecution he had suffered in

Pakistan because of his membership in a particular organization. See Janjua, 933

F.3d at 1063. At one point during the asylum hearing, the government asked about

the organization’s reputation for violence and cited to some supporting documents.

See id. But the issue of whether the organization qualified as a terrorist organization

was never raised or discussed. See id. The immigration judge granted the alien

asylum, but when he applied for adjustment of status, USCIS declared him

inadmissible for having provided material support to a terrorist organization. See id.

at 1064. The alien argued that whether he was inadmissible under the terrorism bar

had been decided in his asylum proceeding, and that the doctrine of issue preclusion

therefore barred USCIS from re-adjudicating the issue. See id.

The Ninth Circuit, however, held that issue preclusion did not apply because

the alien’s inadmissibility under the terrorism bar had not been actually litigated in

the asylum proceeding. See id. at 1068–69. Neither of the critical issues—whether

14
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 15 of 29

the organization qualified as a terrorist organization or whether the alien had

engaged in terrorist activity—had been raised or submitted for determination by the

parties in his asylum proceeding. See id. at 1067. Additionally, although the alien’s

membership in and work for the organization (including whether he had used

violence to further the organization’s goals) had been discussed at the asylum

hearing, these topics had been explored to determine fear of persecution as opposed

to inadmissibility under the terrorism bar. See id. at 1067–68. Indeed, “no one raised,

or even hinted at, these topics as potential grounds for inadmissibility under [the

terrorism bar].” Id. at 1067.

As in Janjua, no one raised or submitted for determination at Mr. Islam’s

asylum hearing whether the BNP qualified as a Tier III terrorist organization, let

alone whether Mr. Islam had provided material support to such an organization. Mr.

Islam, moreover, points to nothing in the record indicating that evidence relevant to

those subjects was discussed during the asylum hearing. Instead, the statements that

he relies on were ones he or the asylum officer made prior to the hearing. To the

extent that the immigration judge considered those statements during the asylum

proceeding, he did so only to determine whether Mr. Islam had a credible fear of

persecution.

Mr. Islam cites to Amrollah v. Napolitano, 710 F.3d at 571, where the Fifth

Circuit held that an alien’s inadmissibility under the terrorism bar had been actually

15
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 16 of 29

litigated in a prior asylum proceeding. The case, however, is distinguishable on its

facts. In Amrollah, the Fifth Circuit concluded that the “actually litigated” element

of issue preclusion was satisfied as to the terrorism bar because “[t]he government

cross-examined [the alien] extensively about his support of the mujahedeen

movement and [the relevant organization] during the asylum proceeding.” Id.

Additionally, the immigration judge had explicitly found that the alien’s testimony

confirmed that he had not supported any acts of violence that would make him

ineligible for asylum, in spite of the government’s suggestion otherwise. See id. at

570. That record is different than the one before us. Mr. Islam was not cross-

examined on his BNP membership or whether he provided material support to the

BNP. Nor did the government suggest during the asylum proceeding that he might

be inadmissible under the terrorism bar. Finally, unlike the immigration judge in

Amrollah, the immigration judge here made no mention of the terrorism bar in his

one-page order granting asylum.

We discern no clear error in the district court’s determination that Mr. Islam’s

inadmissibility under the terrorism bar was not actually litigated during the asylum

proceeding, and reject the issue preclusion claim. Given our conclusion, we do not

address the other requirements of issue preclusion.

16
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 17 of 29

V

Mr. Islam next argues that, in violation of his due process rights under the

Fifth Amendment, the definition of a Tier III terrorist organization under

§ 1182(a)(3)(B)(vi)(III) and the definition of “terrorist activity” under

§ 1182(a)(3)(B)(iii)(V)(b) & (VI) are unconstitutionally overbroad and vague. We

address each of these arguments below.

A

It is unclear whether Mr. Islam is asserting that the statutory provisions in

question are unconstitutional under the First Amendment overbreadth doctrine, or

whether he is simply using the words “broad” and “overbroad” to buttress his

vagueness argument. If it is the former, Mr. Islam’s overbreadth arguments fail at

the threshold.

For starters, Mr. Islam has abandoned any argument that the definition of a

Tier III terrorist organization fails under overbreadth principles. He mentions the

supposed overbreadth of § 1182(a)(3)(B)(vi)(III) in his initial brief only in passing,

without developing any substantive arguments. And he does not quote or discuss the

First Amendment overbreadth standard, which is that “a law may be invalidated as

overbroad if ‘a substantial number of its applications are unconstitutional, judged in

relation to the statute’s plainly legitimate sweep.’” United States v. Stevens, 559

U.S. 460, 473 (2010) (citation omitted).

17
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 18 of 29

“We have long held that an appellant abandons a claim when he either makes

only passing references to it or raises it in a perfunctory manner without supporting

arguments and authority.” Sapuppo v. Allstate Floridian Ins. Co., 739 F.3d 678, 681

(11th Cir. 2014). Mr. Islam’s fleeting references to § 1182(a)(3)(B)(vi)(III) being

“broad” and “overbroad” constitute abandonment of any overbreadth claim.

In addition, Mr. Islam has waived any challenge to the definition of “terrorist

activity” under § 1182(a)(3)(B)(iii)(V)(b) & (VI), because he intentionally

relinquished it in the district court. See United States v. Gonzalez, 834 F.3d 1206,

1217 (11th Cir. 2016) (“[W]aiver is the intentional relinquishment or abandonment

of a known right. If a party waives an argument in the district court, we will not

review it on appeal.”) (citations and internal quotation marks omitted). In his

objections to the magistrate judge’s report and recommendation, Mr. Islam told the

district court that he was not challenging the definition of “terrorist activity” and

confirmed that the definition of a Tier III terrorist organization under

§ 1182(a)(3)(B)(vi)(III) “[was] the only part of the statute in dispute.” D.E. 29 at 9.

In doing so, he waived any overbreadth challenge to § 1182(a)(3)(B)(iii)(V)(b) &

(VI).

B

Mr. Islam asserts that the definitions of a Tier III terrorist organization, see

§ 1182(a)(3)(B)(vi)(III), and “terrorist activity,” see § 1182(a)(3)(B)(iii)(V)(b) &

18
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 19 of 29

(VI), are unconstitutionally vague. We reject the first argument on the merits, and

conclude that the second argument has been waived.

1

A claim that a statute is vague, and therefore unconstitutional, presents a

question of law subject to plenary review. See Wilson v. State Bar of Ga., 132 F.3d

1422, 1427 (11th Cir. 1998). A law is unconstitutionally vague when “it fails to

give ordinary people fair notice of the conduct it punishes, or [is] so standardless

that it invites arbitrary enforcement.” Johnson v. United States, 576 U.S. 591, 595

(2015). Where, as here, a vagueness challenge does not involve the First

Amendment, the statute in question is generally analyzed on an as-applied basis. See

Maynard v. Cartwright, 486 U.S. 356, 361 (1988); Village of Hoffman Estates v.

Flipside, Hoffman Ests., Inc., 455 U.S. 489, 495 n.7 (1982). The questions for us,

then, are whether §§ 1182(a)(3)(B)(vi)(III) and 1182(a)(3)(B)(iii)(V)(b) & (VI) are

sufficiently clear in their application to Mr. Islam’s case. See Holder v.

Humanitarian L. Project, 561 U.S. 1, 21 (2010).

As to the definition of a Tier III terrorist organization, Mr. Islam claims that

it is unconstitutionally vague because it does not indicate how an organization

itself—as opposed to its members or leaders—engages in the prohibited conduct.

To recall, a Tier III terrorist organization is defined as “an organization . . . that is a

group of two or more individuals, whether organized or not, which engages in, or

19
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 20 of 29

has a subgroup which engages in [certain activities, including ‘terrorist activity.’]”

§ 1182(a)(3)(B)(vi)(III). Because that provision requires an entity itself to have

engaged in terrorist activity but does not indicate how the entity can do so, Mr. Islam

says that it is vague and therefore void.

We hold that an organization engages in terrorist activity for the purposes of

§ 1182(a)(3)(B)(vi)(III) when its members perpetrate terrorist activity and its

leadership authorizes such conduct expressly or tacitly. The text of

§ 1182(a)(3)(B)(vi)(III) “speaks to concerted actions of a group, not uncoordinated

activities by individual members: an organization receives Tier III status only if a

group itself engages in terrorist activity.” Uddin, 870 F.3d at 290. Thus, “[a] rule that

there must be evidence of authorization from party leaders is most faithful to that

statutory text.” Id. “If an activity is not authorized, ratified, or otherwise approved

or condoned by the organization, then the organization is not the actor.” Hussain v.

Mukasey, 518 F.3d 534, 538 (7th Cir. 2008). Authorization must be determined on

a case-by-case basis, and may be inferred from, among other things, “the fact that

most of an organization’s members commit terrorist activity or from a failure of a

20
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 21 of 29

group’s leadership to condemn or curtail its members’ terrorist acts.” Uddin, 870

F.3d at 292 (internal quotation marks omitted).3

Our holding does not mean that an organization qualifies as a Tier III terrorist

organization if it fails to prevent one or a few terrorist acts by its members or fails

to stop a single member from committing terrorist acts. Indeed, “[i]f a single member

of the Democratic or Republican Party committed a terrorist act, we would not

impute terrorist status to the entire group, absent some showing that party leadership

authorized the act.” Id. at 290. See also Khan v. Holder, 766 F.3d 689, 699 (7th Cir.

2014) (“An entire organization does not automatically become a terrorist

organization just because some members of the group commit terrorist acts. The

question is one of authorization.”). But when the terrorist activity of its members is

recurrent and extends over a prolonged period, and leadership’s failure to curtail that

activity is likewise consistent, a trier of fact can reasonably infer that the

organization authorized its members’ terrorist activity.

As applied to Mr. Islam and the BNP, § 1182(a)(3)(B)(vi)(III) is not

unconstitutionally vague. “[T]he vagueness doctrine bars enforcement of a statute

which either forbids or requires the doing of an act in terms so vague that men of

In his initial brief, Mr. Islam recognizes this case law but argues against it because interpreting
and applying an authorization requirement would be problematic. He does not, however, raise a
convincing substantive challenge to the analyses of the Third and Seventh Circuits.

 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 22 of 29

common intelligence must necessarily guess at its meaning and differ as to its

application.” United States v. Lanier, 520 U.S. 259, 266 (1997) (internal quotation

marks omitted). Here, USCIS found that BNP members had repeatedly and for a

prolonged period—from the mid-1990s to 2015—engaged in conduct that

constituted terrorist activity, and that BNP leadership had consistently and

systematically failed to curtail such activity. A person of common intelligence would

have been on fair notice that the BNP could meet the definition of a Tier III terrorist

organization. And even if, in the abstract, § 1182(a)(3)(B)(vi)(III) suffers from some

ambiguity, see Hussain, 518 F.3d at 538, the decisions of our sister circuits provided

fair warning that the BNP falls within the scope of the terrorism bar. See Uddin, 870

F.3d at 290; Khan, 766 F.3d at 699; Hussain, 518 F.3d at 538. See also Lanier, 520

U.S. at 266 (“clarity at the requisite level may be supplied by judicial gloss on an

otherwise uncertain statute”).4

Mr. Islam argues in his reply brief that “only direct authorization, such as

verbal or written permission, orders, or instructions to carry out terrorist activity,”

can lead to a Tier III terrorist organization classification because “[s]uch [a]

definition is clear; it is just; it is rational; and it can be proved or disproved.”

Appellant’s Reply Br. at 14–15. Establishing the existence (or lack thereof) of

Our general statements about the BNP should not be read as suggesting that Tier III status can
be determined on anything other than a case-by-case basis.
22
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 23 of 29

explicit authorization may be more straightforward than establishing the existence

(or lack thereof) of tacit authorization, but this does not make

§ 1182(a)(3)(B)(vi)(III), as construed, unconstitutionally vague. Difficulty in proof

does not equate to unconstitutional vagueness. Indeed, in some contexts we consider

entities which tacitly authorize or ratify conduct to themselves be at fault, and that

cuts against Mr. Islam’s contention that a tacit authorization requirement is unclear,

irrational, and unconstitutional. Cf. Brooks v. Scheib, 813 F.2d 1191, 1193 (11th Cir.

1987) (“A municipality’s failure to correct the constitutionally offensive actions of

its police department may rise to the level of a custom or policy [under 42 U.S.C.

§ 1983] if the municipality tacitly authorizes these actions[.]”) (internal quotation

marks omitted).

2
That leaves Mr. Islam’s vagueness challenge to the definition of “terrorist

activity.” That, term, again, is defined as “any activity which is unlawful” and which

involves the use of explosives, firearms, weapons, or dangerous devices—“other

than for mere personal monetary gain”—“with intent to endanger, directly or

indirectly, the safety of one or more individuals or to cause substantial damage to

property,” as well as a “threat, attempt, or conspiracy” to do any of these acts. See

§ 1182(a)(3)(B)(iii)(V)(b) & (VI).

23
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 24 of 29

This definition is problematic, says Mr. Islam, because it encompasses actions

that no reasonable person would define as terrorist activities. He argues, for

example, that there is no self-defense exception. And he insists that it is irrational

to use such a broad definition when someone in his position may be associated with

a terrorist organization just because others in the organization may have committed

prohibited acts. See Appellant’s Br. at 31.

Mr. Islam’s vagueness challenge to § 1182(a)(3)(B)(iii)(V)(b) & (VI) fails at

the outset. As we explained earlier, he intentionally relinquished any challenge to

the definition of “terrorist activity” in the district court. See Gonzalez, 834 F.3d at

1217. He therefore cannot present the vagueness challenge on appeal.

VI

As to USCIS’ substantive determination that the BNP qualified as a Tier III

terrorist organization, Mr. Islam argues that there is no evidence that BNP leaders

authorized terrorist activity that may have been carried out by its members.

According to Mr. Islam, USCIS’ decision is arbitrary and capricious. We disagree.

In conducting de novo review of the district court’s grant of summary

judgment, we apply the same underlying standard used by the district court. See

Gerling Glob. Reinsurance Corp. of Am. v. Gallagher, 267 F.3d 1228, 1233 (11th

Cir. 2001). The relevant provision of the Administrative Procedure Act, 5 U.S.C.

§ 706(2)(A), authorizes a court to set aside an agency’s action if it is “arbitrary,

24
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 25 of 29

capricious, an abuse of discretion, or otherwise not in accordance with law.” Under

that deferential standard, we assess whether the agency’s decision demonstrates a

“rational connection between the facts found and the choice made.” Motor Vehicle

Mfrs. Ass’n of U.S., Inc. v. State Farm Mut. Auto. Ins. Co., 463 U.S. 29, 43 (1983)

(internal quotation marks omitted). See also BBX Cap. v. Fed. Deposit Ins. Corp,

956 F.3d 1304, 1314 (11th Cir. 2020). Our role “is to ensure that the agency came

to a rational conclusion, not to conduct [our] own investigation and substitute [our]

own judgment for the administrative agency’s decision.” Sierra Club v. Van

Antwerp, 526 F.3d 1353, 1360 (11th Cir. 2008) (internal quotation marks omitted).5

USCIS determined that the BNP qualified as a Tier III terrorist organization,

finding (1) that over many years BNP members had engaged in frequent and

widespread conduct that constituted terrorist activity, (2) that BNP leadership

sometimes participated in or threatened the use of violence, and (3) that there was

no evidence that BNP leadership took steps to prevent members from engaging in

terrorist activity or routinely sanctioned members for doing so. Consequently,

5
Under § 706(2) of the APA, courts can set aside agency actions in six circumstances. We
understand Mr. Islam to argue that USCIS’ decision is arbitrary and capricious in violation of
§ 706(2)(A) because he cites only the standard of review for that provision, argues that USCIS’
determinations are not rational, and concludes that “USCIS violated the APA in making the
irrational, arbitrary, and capricious finding that the BNP meets the definition of a Tier III terrorist
group.” Appellant’s Br. at 34. Mr. Islam summarily mentions that USCIS’ findings and
conclusions are not supported by substantial evidence, see § 706(2)(E), but does not cite or discuss
that standard. We therefore do not address it. See Sapuppo, 739 F.3d at 681.
25
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 26 of 29

USCIS determined that the BNP had at least tacitly authorized its members’ terrorist

activity, thereby itself engaging in terrorist activity.

We conclude that USCIS rationally found that BNP members had engaged in

conduct that constituted “terrorist activity” under § 1182(a)(3)(B)(iii)(V)(b) & (VI).

For example, a Human Rights Watch report on Bangladesh’s 1996 elections

explained that BNP members had engaged in wanton acts of violence and

intimidation. Specifically, BNP and AL members “ha[d] used crude ‘cocktail’

bombs, knives, and guns against one another and the police, causing scores of

casualties.” D.E. 18-3 at 4. Reuters further reported that a 1997 strike called by the

BNP had been enforced by strikers who set off dozens of homemade bombs. The

Committee to Protect Journalists reported that, in 1999, a group of BNP

demonstrators stormed an office building housing a local newspaper. Armed with

explosives, guns, rocks, and sticks, the demonstrators injured eighteen newspaper

staffers and damaged fourteen newspaper vehicles. A Jane’s Sentinel Security

Assessment reported that BNP protests leading up to the 2014 elections resulted in

hundreds of deaths, and that protesters threw rocks and Molotov cocktails at

government property. That evidence was sufficient for USCIS to rationally conclude

that BNP members had engaged in conduct that constituted terrorist activity under

§ 1182(a)(3)(B)(iii)(V)(b) & (VI).

26
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 27 of 29

USCIS’ determination that BNP leaders had tacitly authorized its members’

terrorist activity was also rational. Here too, the 1996 Human Rights Watch report

explained that, after that year’s election, “neither the BNP nor the [AL] ha[d] taken

affirmative steps to ensure that their supporters and party cadres desist[ed] from the

kind of violence that characterized their earlier political feuding.” D.E. 18-3 at 4.

After the 1999 attack on a local newspaper, the newspaper’s editor stated that the

attack had been spearheaded by the BNP’s press advisor. In addition, other

journalists had reported being threatened by local BNP leaders to not publish reports

critical of the BNP. Against this backdrop, USCIS explained that there was no

evidence in the record that BNP leadership had routinely or systematically

sanctioned members for engaging in terrorist activity. Given the frequent and

widespread nature of the terrorist activity perpetrated by BNP members, all of this

evidence was sufficient to render rational USCIS’ determination that the BNP had

tacitly authorized its members’ terrorist activity.

Mr. Islam presents a series of factual arguments that, while individually

accurate, do not change the outcome. For example, he correctly points out that the

BNP has denied involvement in intimidation and violence. Yet if we were to re-

weigh that fact (and others) along with the evidence supporting USCIS’ tacit

authorization finding, we would be engaging in precisely the type of investigation

and substitution of judgment that we cannot undertake under § 706(2)(A). See Sierra

27
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 28 of 29

Club, 526 F.3d at 1360. We are limited to considering whether an agency’s

determination bears a rational connection to the facts found. See State Farm, 463

U.S. at 43.

We recognize that there is evidence demonstrating that the AL, when in

power, persecuted the BNP and its members. But though that evidence may suggest

that the AL is itself a Tier III terrorist organization, it does not exempt the BNP from

such classification.

Mr. Islam also contends that USCIS and the district court failed to fully

address his argument that he did not know and should not reasonably have known

that the BNP qualified as a Tier III terrorist organization. We agree with the

government, however, that Mr. Islam has forfeited his lack-of-knowledge argument

by not raising it in the district court. See Access Now, Inc. v. Sw. Airlines Co., 385

F.3d 1324, 1331 (11th Cir. 2004). In any event, USCIS did explain its conclusion

that Mr. Islam had not met his burden of proving that he did not know and should

not reasonably have known that the BNP qualified as a Tier III terrorist organization.

See D.E. 18-1 at 9. Mr. Islam’s argument on appeal—which does not identify any

substantive error in USCIS’ analysis—is perfunctory and therefore insufficient. See

Sapuppo, 739 F.3d at 681. Thus, we leave for another day what a person must show

to establish that he “did not know, and should not reasonably have known, that the

organization was a terrorist organization.” § 1182(a)(3)(B)(iv)(VI)(dd).

28
 USCA11 Case: 19-13287 Date Filed: 05/20/2021 Page: 29 of 29

Applying the “exceedingly deferential” standard of review under § 706(2)(A)

of the APA, see Sierra Club, 526 F.3d at 1360, we hold that USCIS’ conclusion that

the BNP authorized its members’ terrorist activity—and thus qualified as a Tier III

terrorist organization—is not arbitrary and capricious. Mr. Islam’s APA challenge

therefore fails.6

VII

We affirm the district court’s grant of summary judgment in favor of the

government on Mr. Islam’s claims.

AFFIRMED.

6
As indicated earlier, USCIS found Mr. Islam inadmissible on two grounds—that he is a member
of a Tier III terrorist organization and that he engaged in terrorist activity by providing material
support to a Tier III terrorist organization. See § 1182(a)(3)(B)(i)(VI) & (iv)(VI)(dd). Both grounds
depend on the BNP qualifying as a Tier III terrorist organization, and it is that determination by
USCIS that Mr. Islam challenges on appeal. He does not contest USCIS’ finding that he provided
material support to the BNP. Hence, our affirmance under § 706(2)(A) of USCIS’ finding that the
BNP qualifies as a Tier III terrorist organization is dispositive as to both grounds of inadmissibility.
