Karen Guidi, Eve Hoffman, Merrill Kramer, and Lois Kramer (“Plaintiffs”) sued Inter-Continental Hotels Corporation and other defendants (collectively “IHC”) on personal injury and wrongful death claims arising from a shooting in an Egyptian hotel managed by IHC. The United States District Court for the Southern District of New York, Loretta A. Preska, Judge, dismissed Plaintiffs’ action on the ground of forum non conveniens, concluding that Egypt was the better forum for their suit. Plaintiffs now appeal this dismissal, arguing that the District Court applied the wrong legal standard for determining the proper forum in this case and mistakenly relied on the existence of related litigation in favor of the Egyptian forum. Because we agree with Plaintiffs that the District Court erred in concluding *182that their action should be heard in Egypt, we reverse.
BACKGROUND
In October 1993, Robert Guidi, Coby Hoffman, and Merrill Kramer were in Egypt on business. While eating dinner in the restaurant of the Semiramis InterContinental Hotel, which at the time was managed by IHC, all three men were shot by an Egyptian gunman named Farahat who had entered the hotel without triggering the suspicions of hotel security. In addition to the three Americans, Farahat shot a Syrian lawyer, a French lawyer, and an Italian judge. Of his six victims, four died, including Robert Guidi and Coby Hoffman.
Immediately after the shooting, Farahat surrendered to hotel security and the Egyptian police. His claimed motivation for the shootings was religious extremism directed against foreigners. In the criminal prosecution that followed, Farahat was adjudged insane and committed to a government hospital in January 1994. He escaped from the hospital in September 1997 and the same day, with the help of at least one other person, killed ten more people in an attack on a tour bus.
Plaintiffs filed suit against IHC on October 20, 1995, joining the wrongful death claims of' Guidi’s and Hoffman’s widows with the personal injury claims of Kramer and his wife. At the time of suit, Mrs. Guidi and Mrs. Hoffman were residents of New Jersey and the Kramers resided in Maryland. Because IHC is a Delaware company with its principal place of business in New York City and diversity existed between the parties, Plaintiffs elected to bring their action in the Southern District of New York. On July 7, 1996, IHC moved for dismissal on the ground of forum non conveniens, arguing that information critical to its defense could be obtained only in Egypt, that the cost of defending itself in New York would be prohibitive, that it would be unable to im-plead Egyptian third parties, and that an Egyptian court would better be able to apply Egyptian tort law. Plaintiffs opposed IHC’s motion on several fronts, including that American plaintiffs should not be compelled to sue an American defendant in a foreign country and that Plaintiffs were emotionally unable to travel to Egypt for a trial.
In January 1997, IHC submitted supplemental information to the District Court which indicated that the families of the Italian judge and the French lawyer, whom Farahat had killed in the same incident that gave rise to this case, had commenced wrongful death actions in the Egyptian courts.
On July 17, 1997, the District Court granted IHC’s motion to dismiss.1 Applying the forum non conveniens balancing test outlined by the Supreme Court in Gulf Oil Corp. v. Gilbert, 330 U.S. 501, 67 S.Ct. 839, 91 L.Ed. 1055 (1947), the court found that with respect to the private interests of the litigants, the balance slightly favored the Egyptian forum because a viewing of the premises would be possible there and because IHC would be able to implead the Egyptian government as a third party. Turning to the public interest factors presented by the case, the court found that (1) the Southern District of New York has an overburdened docket; (2) Egypt has a greater interest in the litigation than New York because it is committed to protecting its tourist industry; (3) an Egyptian court would be more familiar with Egyptian law and have a greater interest in its application; and (4) most significantly, there were two related lawsuits pending in Egypt at *183the time of dismissal. The court concluded that these public interest factors decisively favored the Egyptian forum, and dismissed the case on that basis.
In November 1997, Plaintiffs filed for relief from the district court’s dismissal under Fed.R.Civ.P. 60(b)(6), providing evidence of increasing terrorist activity against tourists in Egypt since the time of the dismissal. Plaintiffs’ evidence included the escape and subsequent killing of nine tourists by Farahat in September 1997, as well as the terrible attack at Luxor in November 1997 that resulted in the deaths of more than 50 foreigners. Plaintiffs’ motion was denied by an order dated April 16,1999.
Plaintiffs challenge both the dismissal of their action and the denial of relief under Rule 60(b)(6) in this consolidated appeal. Plaintiffs argue primarily that the district court applied an incorrect legal standard for cases in which an American plaintiff seeks an American forum and relied excessively on the existence of related litigation in Egypt. Plaintiffs also question the district court’s failure to give proper weight to the emotional toll and threats to personal safety faced by Plaintiffs if forced to bring their action in Egypt.
DISCUSSION
We have recognized that our review of a forum non conveniens dismissal is limited to whether a district court abused its broad discretion to dismiss on such grounds. Peregrine Myanmar Ltd. v. Segal, 89 F.3d 41, 46 (2d Cir.1996); Scottish Air Int’l, Inc. v. British Caledonian Group, PLC, 81 F.3d 1224, 1232 (2d Cir.1996). Our limited review, however, encompasses “the right to determine whether the district court reached an erroneous conclusion on either the facts or the law.” R. Maganlal & Co. v. M.G. Chem. Co., 942 F.2d 164, 167 (2d Cir.1991) (internal quotation omitted).
Plaintiffs believe that the district court abused its discretion in at least two ways by deciding that Egypt was the better forum for this case. First, Plaintiffs argue that the district court failed to apply the forum non conveniens standard articulated in Roster v. Lumbermens Mut. Cds. Co., 330 U.S. 518, 524, 67 S.Ct. 828, 91 L.Ed. 1067 (1947), which Plaintiffs assert should control in a case such as theirs in which an American plaintiff has chosen to sue in his home forum. Second, Plaintiffs contest the significance given by the district court to the related wrongful death cases pending in Egypt at the time of its decision, and argue that the district court confused forum non conveniens with transfer to another federal court under 28 U.S.C. § 1404(a). We agree with Plaintiffs on both points. Moreover, we believe that the special circumstances presented by this case—specifically, the emotional burden on Plaintiffs of returning to the country where they or their loved ones were shot in an act of religious terrorism—provide additional weight for favoring Plaintiffs’ choice of their home forum for this litigation.
I. Home Forum under Roster
In 1947, the Supreme Court decided the companion cases Roster, 330 U.S. 518, 67 S.Ct. 828, 91 L.Ed. 1067 (1947), and Gilbert, 330 U.S. 501, 67 S.Ct. 839, 91 L.Ed. 1055 (1947). In these two cases, the Court laid out the approach to forum non conveniens that is still followed in federal courts today.2 See, e.g., Piper Aircraft Co. v. Reyno, 454 U.S. 235, 241, 102 S.Ct. 252, 70 L.Ed.2d 419 (1981); Scottish Air Int’l, 81 F.3d at 1232. In Gilbert, which involved a plaintiff who brought suit outside his home forum, see 330 U.S. at 502, 67 *184S.Ct. 839, the Court set forth a balancing test of private and public interests to guide courts’ discretion in determining whether a more convenient forum exists. See id. at 508-09, 67 S.Ct. 839. While Gilbert acknowledged generally that “the plaintiffs choice of forum should rarely be disturbed,” id. at 508, 67 S.Ct. 839, Koster, which involved a plaintiff who had chosen to sue in his home forum, more explicitly stated that:
Where there are only two parties to a dispute, there is good reason why it should be tried in the plaintiffs home forum if that has been his choice. He should not be deprived of the presumed advantages of his home jurisdiction except upon a clear showing of facts which either (1) establish such oppressiveness and vexation to a defendant as to be out of all proportion to plaintiffs convenience, which may be shown to be slight or nonexistent, or (2) make trial in the chosen forum inappropriate because of considerations affecting the court’s own administrative and legal problems. In any balancing of conveniences, a real showing of convenience by a plaintiff who has sued in his home forum will normally outweigh the inconvenience the defendant may have shown.
330 U.S. at 524, 67 S.Ct. 828. Thus, where a plaintiff sues in his or her home forum, a court is required to keep the ease in the home forum unless the defendant can “establish such oppressiveness and vexation ... as to be out of all proportion to plaintiffs convenience.” Id.; see also American Dredging Co., 510 U.S. at 447-48, 114 S.Ct. 981.
In this case, Plaintiffs argue— and we agree — that their “home forum” as American citizens is a United States court, such as the courts of the Southern District of New York.3 Although a citizen’s choice of forum is not “dispositive” for the purposes of forum non conveniens, Piper Aircraft, 454 U.S. at 255 n. 23, 102 S.Ct. 252, the choice of an American court over a foreign court should be given the heightened deference detailed in Roster. Here, the district court did not apply the Roster standard, but rather relied exclusively on a discussion of the Gilbert private and public interest factors. This omission and consequent failure to grant Plaintiffs’ choice of an American forum significant deference was unsound.
Under the standard articulated in Roster, Plaintiffs’ decision to sue in New York should not be disturbed if that forum is not so oppressive and vexatious to IHC as to overwhelm the convenience to Plaintiffs of suing in their home forum. See 330 U.S. at 524, 67 S.Ct. 828. Additionally, the convenience of the New York forum to Plaintiffs must be real and substantial, as opposed to slight or nonexistent.4 See id. These criteria are easily met in this case: IHC is a corporate defendant with its principal place of business in New York and is being sued for a relatively simple tort violation. Plaintiffs, in contrast, are ordinary American citizens for whom litigating in Egypt presents an obvious and significant inconvenience, especially considering their adverse experience with that country to *185date. This is not a case where the plaintiff is a corporation doing business abroad and can expect to litigate in foreign courts. See Reid-Walen, 933 F.2d at 1395 (courts partially discount citizenship when plaintiff does extensive foreign business); Contact Lumber Co. v. P.T. Moges Shipping Co., 918 F.2d 1446, 1449-50 (9th Cir.1990) (same) (citing Mizokami Bros, of Ariz., Inc. v. Baychem Corp., 556 F.2d 975, 978 (9th Cir.1977)). Under the circumstances presented here, we can see, no reason to make an exception to the holding in Koster that “a real showing of convenience by a plaintiff who has sued in his home forum will normally outweigh the inconvenience the defendant may have shown.” See 330 U.S., at 524, 67 S.Ct. 828.
Indeed, the district court, in its analysis of the private interest factors under Gilbert, concluded that the degree of inconvenience to IHC of litigating in the United States did not offer a basis for dismissing the case. After considering IHC’s arguments regarding its need to implead Egypt as a third party, the availability of witnesses and evidence, the cost of obtaining depositions, and the possibility of a jury view in Egypt, the district court found that these factors “d[id] not strongly favor” the Egyptian forum. See Guidi v. Inter-Continental Hotels Corp., No. 95 CIV. 9006(LAP), 1997 WL 411469, at *3 (S.D.N.Y. July 18, 1997). IHC therefore did not carry its burden under Koster to demonstrate that New York was such an oppressive and vexatious forum as to be “out of all proportion” to its demonstrated convenience to Plaintiffs.
Because the district court failed to apply the Koster standard and gave inadequate significance to Plaintiffs’ choice of forum as American citizens, we find that its determination that Egypt was the better forum for this litigation was erroneous. Plaintiffs’ decision to bring their suit in New York rather than in a foreign country should not be disturbed.
II. The Related Litigation
In its weighing of the Gilbert public interest factors to determine the best forum for this case, the district court stated that the strongest public interest factor in favor of the Egyptian forum was the related litigation pending there at the time of its decision. The district court found that because the families of two other hotel guests who were killed by Farahat had brought suit in Egypt, although not against IHC, it would be most efficient if Plaintiffs’ claims were heard in Egypt as well. To support its finding, the district court cited several cases based on 28 U.S.C. § 1404(a) which hold that related litigation -in the transferee forum weighs heavily in favor of transfer.
The district court’s reliance on 28 U.S.C. § 1404(a), which controls the transfer of cases among the federal courts within the United States, was not correct. As the Supreme Court recognized in Piper Aircraft, “§ 1404(a) transfers are different than dismissals on the ground of forum non conveniens. ... District courts [a]re given more discretion to transfer under § 1404(a) ... [because] [t]he statute was designed as a ‘federal housekeeping measure,’ allowing easy change of venue within a unified federal system.” 454 U.S. at 253-54, 102 S.Ct. 252 (quoting Van Dusen v. Barrack, 376 U.S. 612, 613, 84 S.Ct. 805, 11 L.Ed.2d 945 (1964)). When, as here, the alternative forum is the court of a foreign country, the law of § 1404(a) has no application because “the differences between trial in an American court and a foreign court will almost inevitably be greater than those between trial in two federal courts- in the United States.” Nalls v. Rolls-Royce Ltd., 702 F.2d 255, 261 (D.C.Cir.1983).
The existence of related litigation, while of major significance in § 1404(a) cases, is not listed as a relevant factor in the forum non conveniens analysis laid out in Gilbert. 330 U.S. 518-19, 67 S.Ct. 828. Moreover, we can find no case that gives such litigation the significance accorded by the dis-*186triet court here, when the parties in the related action are completely different from the parties at bar. In the two forum non conveniens cases cited by the district court to support its decision, the parties to the American and foreign actions were identical and there was the likelihood of “significant duplication of legal efforts on behalf of all the parties.” C-Cure Chem. Co. v. Secure Adhesives Corp., 571 F.Supp. 808, 822 (W.D.N.Y.1983); see also Ocean Shelf Trading, Inc. v. Flota Mercante Grancolombiana S.A., 638 F.Supp. 249, 253 (S.D.N.Y.1986). The private interests of the litigants — relevant under Gilbert— were therefore implicated in these cases in a manner not present here. We are not persuaded that such cases, in the absence of more apposite authority, require us to uphold the reasoning of the district court that Plaintiffs’ case would be more efficiently heard in Egypt.
Although we are unwilling to say that the existence of related litigation in another country should never be considered for the purposes of forum non conveniens, we conclude that it was unsound for the district court to rely on § 1404(a) in giving the Egyptian litigation such decisive weight in this case.
III. Plaintiffs’ Emotional Burden
Having found that the district court abused its discretion in dismissing Plaintiffs’ action in favor of the Egyptian forum, we need no further basis for reversing the decision below. However, we believe that the substantial and unusual emotional burden on Plaintiffs if they were required to travel to Egypt provides additional support for keeping the case in their chosen forum of New York.
Plaintiffs are atypical in that they are either the widows or the victim of a murderous act directed specifically against foreigners. Understandably, they are strongly adverse to litigating in a country where foreigners have been the target of hostile attacks, and have concerns for their own safety if required to travel there to bring their suit. Plaintiffs have supplied us with ample evidence of terrorist attacks occurring after the events giving rise to their action — including the subsequent killing of nine foreign tourists by the very man who attacked Plaintiffs — which give credence to Plaintiffs’ uncertainty as to the safety of American visitors to Egypt insofar as fear of religious extremism is concerned.
In its forum non conveniens analysis, the district court did not even mention, much less give any weight to, the emotional burden faced by Plaintiffs if the case were to be heard in Egypt. In the subsequent Fed.R.Civ.P. 60(b) motion filed by Plaintiffs on this specific point, the district court affirmed its decision to dismiss the case in favor of the Egyptian forum, and rejected the argument that Plaintiffs’ concerns tilted the balance in favor of keeping the case in New York. Roster, however, dictates that for the purposes of forum non conveniens, “the ultimate inquiry is where trial will best serve the convenience of the parties and the ends of justice.” 330 U.S. at 527, 67 S.Ct. 828 (emphasis added); see also Maganlal, 942 F.2d at 167. We believe that justice is best served in this case by acknowledging the unique and heavy burden placed on Plaintiffs if they are required to litigate in Egypt. In balancing the interests at stake for the purposes of forum non conveniens, the district court should have taken into account the unusual circumstances of Plaintiffs that weigh strongly in favor of the New York forum.
CONCLUSION
For the foregoing reasons, we find that the district court abused its discretion in deciding that Egypt was the better forum for this litigation. We therefore reverse its dismissal and return the case to the Southern District of New York.
. The Background section of the District Court's Memorandum and Order identifies the basis for IHC’s motion as 28 U.S.C. § 1404, the statute which governs transfers of venue between federal courts within the United States. Because this case does not involve a transfer to another federal court, § 1404 has no application here. The court, however, did not analyze the case under the law of § 1404, but correctly looked to the law of forum non conveniens on all but one point. We address that point in Section II.
. As the Supreme Court has noted, the enactment of 28 XJ.S.C. § 1404 (1998), which controls interstate transfers of cases in federal courts, had the effect of limiting forum non conveniens analyses to cases such as this one where the alternative forum is the court of another country. See American Dredging Co. v. Miller, 510 U.S. 443, 449 n. 2, 114 S.Ct. 981, 127 L.Ed.2d 285 (1994).
. The district court noted in a footnote to its decision that Plaintiffs were not citizens of New York and that the presumption in favor of their choice of the Southern District of New York was therefore weakened. Although the district court did not rely heavily on this fact in concluding that Egypt was the better forum, we find that the states where Plaintiffs reside are not relevant to the forum non con-veniens analysis in this case. See Reid-Walen v. Hansen, 933 F.2d 1390, 1394 (8th Cir.1991) (in a forum non conveniens case involving a foreign court, "the ‘home forum’ for the plaintiff is any federal district in the United States, not the particular district where the plaintiff lives.”).
. The Koster criterion regarding the administrative and legal problems of the chosen court has no application here. Although the district court noted that the Southern District of New York is "heavily overburdened,” the recent filling of all judicial vacancies and the resulting full complement of judges for the District makes this concern of little or no present significance.
