OPINION
LUTTIG, Circuit Judge:Defendant-appellant Harold Owen challenges the district court’s dismissal of his section 2255 motion, which alleged that he was denied the assistance of counsel at his federal arraignment in violation of the Sixth Amendment. Because we conclude that Owen validly waived his right to counsel at the arraignment, and because he suffered no prejudice from his lack of counsel in any event, we affirm the judgment of the district court.
*224I.
Owen was indicted for drug offenses in late 1990. He attended his initial appearance without counsel before a magistrate judge on January 23, 1991. S.J.A. 3. There, he was advised of the charges against him and of his right to counsel. 5.J.A. 3. He alleged that he was financially unable to employ counsel and requested court-appointed counsel, but he executed a financial affidavit that estimated his net worth at $146,900 (mostly in real property) with a monthly income of $2200. 2d S.J.A. 6. The court found him ineligible for court-appointed counsel, but granted him temporary counsel for his imminent detention hearing. 2d S.J.A. 6-7.
On February 4 and February 14, Owen was mailed notice of a hearing for arraignment and for status of counsel. S.J.A. 3. This hearing was held on February 21 before the district judge, and Owen appeared without counsel. J.A. 412-23. The district judge confirmed that Owen had been instructed that he was financially ineligible for a court-appointed attorney, and told him that “given the value of your property there’s no way the tax payers can be asked to foot the bill for your defense,” to which Owen replied, “I understand and appreciate that.” J.A. 415-17, 419-20. The district judge proceeded to arraign Owen, who pleaded not guilty and requested a jury trial. J.A. 420.
Subsequently, the magistrate judge held two status-of-counsel hearings on March 15 and March 25, at which Owen claimed that he was still seeking unsuccessfully to hire counsel and insisted that he should be eligible for a court-appointed attorney. 2d S.J.A. 7. At the second hearing, Owen contended that “his financial condition was not as he had initially reported.” 2d S.J.A. 7.The magistrate judge permitted him to execute a second financial affidavit, which estimated Owen’s net worth at $54,200 with a monthly income of $2278.* 2d S.J.A. 7-8. On that basis, the judge found that Owen was “not financially unable to employ counsel.” 2d S.J.A. 8. The magistrate judge nevertheless appointed counsel for Owen, but he required Owen to reimburse the government for the costs. 2d S.J.A. 8. Owen’s counsel was appointed effective April 9. S.J.A. 4.
At the arraignment on February 21, the district judge had entered a pre-trial order requiring all pre-trial motions to be filed within fifteen days. 2d S.J.A. 18. Prior to appointment of counsel, Owen filed a pro se motion for discovery on March 8 and a pro se motion for a speedy trial on March 22. S.J.A. 3-4. The magistrate judge ruled on the motion for discovery with a standard discovery order on March 25. J.A. 445-57.
Once appointed, Owen’s counsel also filed motions, including a motion for a continuance on April 26, which the district court granted on April 29; and a motion to dismiss on April 26, which the district court denied on April 29. S.J.A. 4. The district judge denied Owen’s motion to dismiss as untimely in light of the fifteen-day deadline for motions in the February 21 pre-trial order, but he considered the merits of the motion in full and made his decision not to excuse its untimeliness in light of his conclusion that it was also legally meritless. 2d S.J.A. 19-21.
Represented by counsel, Owen was tried and convicted on multiple counts on July 23-31. S.J.A. 4-6. His conviction and sentence were upheld on direct appeal. United States v. Owen, 966 F.2d 1445 (4th Cir.1992) (table). In 1997, he *225filed a section 2255 motion in the district court, alleging inter alia that he was unconstitutionally deprived of counsel at his arraignment. J.A. 72. The district court denied his motion, holding that Owen waived his right to counsel at arraignment and that Owen was not prejudiced by lack of counsel in any event. J.A. 376-80. Owen timely appealed. We granted a certificate of appealability only on the issue of Owen’s arraignment without counsel.
II.
As an initial matter, the government does not dispute that Owen was entitled to counsel at his federal arraignment, and so we assume without deciding that Owen’s federal arraignment was a “critical stage” of the criminal proceedings against him, such that his Sixth Amendment right to counsel was applicable. See United States v. Wade, 388 U.S. 218, 227, 87 S.Ct. 1926, 18 L.Ed.2d 1149 (1967) (holding that the Sixth Amendment right to counsel attaches at “critical stages” of criminal process in which “potential substantial prejudice to defendant’s rights inheres”); United States v. Davis, 958 F.2d 47, 48 (4th Cir.1992) (assuming without deciding that federal arraignment is a critical stage implicating the right to counsel).
Assuming that the right to counsel attached, then, we address first the issue of whether Owen waived his right to counsel at his February 21 arraignment hearing. Determination of a waiver of the right to counsel is a question of law, which we review de novo. United States v. Singleton, 107 F.3d 1091, 1097 n. 3 (4th Cir.1997).
The district court’s determination that Owen waived his right to counsel at arraignment was correct. We have held that, when a defendant who is advised of his right to counsel has failed to show that he cannot afford counsel, he impliedly waives his right to counsel by not procuring such from his own resources in a timely fashion. See United States v. Kaufman, 452 F.2d 1202, 1202 (4th Cir.1971) (rejecting the defendant’s claim that he was im-permissibly tried without counsel when he had not submitted financial affidavits establishing his inability to pay and there was “no evidence in the record that Kaufman lacked sufficient funds to retain an attorney to represent him”); Davis, 958 F.2d at 49 (“Having failed to establish ... that he was ever entitled to court appointed counsel, Davis cannot complain that he was arraigned without counsel.”). Moreover, the Sixth Amendment guarantees to a defendant with financial means only “a fair opportunity to secure counsel of his own choice” — not an indefinite series of continuances during which to conduct a leisurely search for counsel on his own schedule. Sampley v. Att’y Gen., 786 F.2d 610, 612 (4th Cir.1986) (emphasis added); see also United States v. Wright, 797 F.2d 171, 174 (4th Cir.1986) (“A defendant may be required to go to trial without an attorney when he has had a fair opportunity to obtain counsel and does not do so.”).
Here, Owen was advised of his right to counsel and his ineligibility for court-appointed counsel at his initial appearance on January 23, and he was arraigned on February 21. He thus had twenty-nine days in which to employ counsel prior to his arraignment. Plainly, this constituted a “fair opportunity” to employ counsel. See Sampley, 786 F.2d at 615 (two two-week continuances between withdrawal of counsel and trial constituted a “fair opportunity” to secure new counsel); see also Davis, 958 F.2d at 47-48 (upholding the defendant’s arraignment without counsel when only nine days had passed between the defendant’s initial appearance, where he was instructed of his right to counsel, *226and his arraignment without counsel). Moreover, there were no exceptional circumstances inhibiting Owen’s search for counsel, cf. Sampley, 786 F.2d at 615 (defendant alleged that the political nature of his case made it impossible to find willing counsel); on the contrary, the arraignment transcript showed that Owen’s failure to obtain counsel was due to his decision to contact only a single attorney who charged an unreasonably high retainer, despite the opportunity to contact other attorneys during those twenty-nine days. See J.A. 415-16.
Owen contends that he was in fact financially unable to secure counsel for himself, relying on the fact that the magistrate judge eventually did provide him with court-appointed counsel. But, in doing so, the magistrate judge explicitly found that Owen was not financially unable to employ counsel, and required Owen to reimburse the court for counsel’s costs. 2d S.J.A. 8. In light of Owen’s affidavits estimating his net worth at $146,000 and $52,000, and the later pre-sentence report placing his net worth at $82,000, it is evident that the magistrate judge did not clearly err in either of his successive determinations that Owen could afford to employ counsel on his own. And even if Owen could now show that he was in fact unable to pay for counsel, contrary to his own affidavits executed at the time, he bore the burden of proving his eligibility for appointed counsel; thus, the district court was entitled to rely on his affidavits in its determination of his eligibility. See Davis, 958 F.2d at 48-49 (“To qualify for court appointed counsel, however, the defendant bears the burden of proving that he lacks financial means to retain counsel.... By blocking legitimate inquiry into his financial condition, a defendant impliedly waives his right to counsel.”). Therefore, Owen effectively waived any right to counsel at his arraignment, and he cannot now complain of a constitutional violation.
III.
Even if Owen had not waived his right to counsel at the arraignment, he would not be entitled to relief because his arraignment without counsel was harmless error, as the district court correctly concluded. We review de novo the district court’s determination that the lack of counsel did not prejudice Owen. Barnes v. Thompson, 58 F.3d 971, 987 (4th Cir.1995).
Assuming, again without deciding, that the arraignment is a critical stage of federal criminal proceedings involving “potential substantial prejudice to defendant’s rights” in the absence of counsel, we must decide whether the absence of counsel at such is subject to harmless-error analysis. We have held that harmless-error analysis applies to the denial of the Sixth Amendment right to counsel at all stages of the criminal process, except for those where such denial “affects and contaminates” the entire subsequent proceeding: “[o]nly in cases where the deprivation of the right to counsel affected — and contaminated — the entire criminal proceeding is reversal automatic.” Arnold v. Evatt, 113 F.3d 1352, 1361 (4th Cir.1997) (internal quotation marks omitted) (quoting Satterwhite v. Texas, 486 U.S. 249, 258, 108 S.Ct. 1792, 100 L.Ed.2d 284 (1988)); see also Arizona v. Fulminante, 499 U.S. 279, 309-10, 111 S.Ct. 1246, 113 L.Ed.2d 302 (1991) (Rehnquist, C.J.) (holding that harmless-error analysis is inapplicable only to “structural defects in the constitution of the trial mechanism,” which affect “[t]he entire conduct of trial from beginning to end”). In particular, with respect to arraignments, the Supreme Court has held that the denial of counsel at an arraignment required automatic reversal, without any harmless-*227error analysis, in two situations: when defenses not pleaded at arraignment were irretrievably lost, Hamilton v. Alabama, 368 U.S. 52, 53-54, 82 S.Ct. 157, 7 L.Ed.2d 114 (1961); and when a Ml admission of guilt entered at an arraignment without counsel was later used against the defendant at trial, despite its subsequent withdrawal, White v. Maryland, 373 U.S. 59, 60, 83 S.Ct. 1050, 10 L.Ed.2d 193 (1963) (per curiam). As the Supreme Court has noted with respect to Hamilton and White, the denial of counsel under such circumstances “east[s] so much doubt on the fairness of the trial process that, as a matter of law, [it] can never be considered harmless.” Satterwhite, 486 U.S. at 256, 108 S.Ct. 1792.
Here, by contrast, Owen’s arraignment without counsel involved no such “structural defect” or “contamination” of the entire trial process. At arraignment, Owen merely entered a plea of not guilty and asserted his right to a jury trial. Unlike the defendants in Hamilton and White, he did not irrevocably waive any defenses or make any irreversible admissions of guilt, nor was he presented with the opportunity to execute any such irrevocable waiver or irreversible admission. On the contrary, Owen preserved every right that he possessed pre-arraignment. He left open the possibility of withdrawing his not-guilty plea; in fact, at arraignment, the government indicated its willingness to engage in plea negotiations with him. J.A. 420-21. In such circumstances, where the arraignment involved no necessary or inevitable impact on the subsequent criminal proceedings, the denial of counsel at arraignment was not “structural error” and is subject to harmless-error analysis.
Our conclusion that Owen’s arraignment without counsel is subject to harmless-error analysis is abundantly supported by Supreme Court cases applying harmless-error analysis to the denial of the Sixth Amendment right to counsel at various “critical stages” of criminal process. For example, in Coleman v. Alabama, the Supreme Court held that an Alabama preliminary hearing was a “critical stage” at which the right to counsel applied, and also held that “[t]he test to be applied is whether the denial of counsel at the preliminary hearing was harmless error under Chapman v. California.’’ Coleman v. Alabama, 399 U.S. 1, 11, 90 S.Ct. 1999, 26 L.Ed.2d 387 (1970). Likewise, in United States v. Wade, the case in which the Supreme Court defined the governing test for determining whether a proceeding is a “critical stage” at which the right to counsel applies, the Court remanded for a determination of whether the error in question was harmless. See Wade, 388 U.S. at 239-40, 87 S.Ct. 1926. And on subsequent occasions, the Court has held that the denial of counsel at various other “critical stages” implicating the Sixth Amendment was subject to harmless-error analysis. See, e.g., Satterwhite, 486 U.S. at 258, 108 S.Ct. 1792 (admission of psychiatric examinations conducted in violation of the Sixth Amendment); Moore v. Illinois, 434 U.S. 220, 232, 98 S.Ct. 458, 54 L.Ed.2d 424 (1977) (denial of counsel at a pre-indictment hearing involving eyewitness identification); Fulminante, 499 U.S. at 310-11, 111 S.Ct. 1246 (admission of a confession elicited in violation of the Sixth Amendment); Milton v. Wainwright, 407 U.S. 371, 372, 92 S.Ct. 2174, 33 L.Ed.2d 1 (1972) (same); see also Sullivan v. Louisiana, 508 U.S. 275, 282-83, 113 S.Ct. 2078, 124 L.Ed.2d 182 (1993) (Rehnquist, C.J., concurring) (“We of course have long since rejected the argument that, as a general matter, the Sixth Amendment prohibits the application of harmless-error analysis in determining whether constitutional error had a prejudicial impact on the outcome of a case.”).
*228In the same vein, we too have held that the list of “critical stages” at which the right to counsel attaches, but at which the denial of counsel does not entail automatic reversal, includes unsupervised and supervised juror visits to the crime scene. See Arnold, 113 F.3d at 1361; Sherman v. Smith, 89 F.3d 1134, 1137 (4th Cir.1996) (en banc). As in all of these cases, the error of which Owen complains did not cast systematic doubt on the subsequent proceedings and did not “affect and contaminate” the entire trial by placing Owen at any ineradicable unfair disadvantage. Accordingly, under both Supreme Court and circuit authority, any error here is subject to review for harmlessness.
Nevertheless, contrary to this extensive authority, Owen contends that denial of counsel at any “critical stage” of the trial process requires automatic reversal. He relies principally on dicta from three Supreme Court opinions suggesting that the denial of counsel at a “critical stage” is not subject to harmless-error analysis. See Bell v. Cone, 535 U.S. 685, 695-96, 122 S.Ct. 1843, 152 L.Ed.2d 914 (2002); Roe v. Flores-Ortega, 528 U.S. 470, 483, 120 S.Ct. 1029, 145 L.Ed.2d 985 (2000); United States v. Cronic, 466 U.S. 648, 659 & n. 25, 104 S.Ct. 2039, 80 L.Ed.2d 657 (1984). For example, in Bell v. Cone, the Supreme Court remarked:
A trial would be presumptively unfair, we said, where the accused is denied the presence of counsel at “a critical stage,” a phrase we used in Hamilton v. Alabama and White v. Maryland to denote a step of a criminal proceeding, such as arraignment, that held significant consequences for the accused.
Bell, 535 U.S. at 695-96, 122 S.Ct. 1843; see also Cronic, 466 U.S. at 659 n. 25, 104 S.Ct. 2039 (“The Court has uniformly found constitutional error without any showing of prejudice when counsel was either totally absent, or prevented from assisting the accused during a critical stage of the proceeding.” (citing Hamilton and White)). However, these statements do not avail Owen’s argument, because they rely on the Supreme Court’s earlier usage of the phrase “critical stage,” in cases such as Hamilton and White, to refer narrowly to those proceedings both at which the Sixth Amendment right to counsel attaches and at which denial of counsel necessarily undermines the reliability of the entire criminal proceeding. See, e.g., Hamilton, 368 U.S. at 53, 82 S.Ct. 157 (holding that Alabama arraignment was a “critical stage” because “[i]t is there that the defense of insanity [and other pleas and motions] must be pleaded, or the opportunity is lost”). As indicated above, the Supreme Court has subsequently used the phrase “critical stage,” in cases such as Wade and Coleman, in a broader sense, to refer to all proceedings at which the Sixth Amendment right to counsel attaches — including those at which the denial of such is admittedly subject to harmless-error analysis. Our unchallenged assumption in this case, namely that Owen’s federal arraignment was a “critical stage” within the meaning of Wade, thus does not commit us to the conclusion that the denial of counsel herein requires automatic reversal. Here, the government has not conceded that harmless-error analysis is inapplicable; on the contrary, the government contends that any error at Owen’s arraignment was evidently harmless. See Br. of Appellee at 11-14. We assume that the right to counsel applied at Owen’s arraignment because the government does not dispute that assumption. But we do not assume that his lack of counsel was structural error — i.e., that his arraignment was a “critical stage” within the narrow meaning of Hamilton and Cronic — because, under our governing law, the error Owen alleges can and must *229be subject to harmless-error analysis. See Satterwhite, 486 U.S. at 256, 108 S.Ct. 1792 (holding that only those “Sixth Amendment violations that pervade the entire proceeding” can “never be considered harmless” (emphasis added)).
Thus, we must determine whether the denial of counsel at arraignment inflicted any prejudice on Owen. In the context of a section 2255 motion alleging constitutional error, such as Owen’s, the Fourth Circuit has not decided whether the harmless-beyond-a-reasonable-doubt standard- of Chapman applies, as it would on direct appeal, see Coleman, 399 U.S. at 11, 90 S.Ct. 1999 (“The test to be applied is whether the denial of counsel at the preliminary hearing was harmless error under Chapman v. California.”), or whether the less stringent test of Brecht v. Ahrahamson applies, as it would on review of a section 2254 petition. See Brecht v. Abrahamson, 507 U.S. 619, 637, 113 S.Ct. 1710, 123 L.Ed.2d 353 (1993) (requiring a section 2254 petitioner alleging constitutional error to show “substantial and injurious effect or influence in determining the jury’s verdict”); see also Griffin v. United States, 330 F.3d 733, 736 (6th Cir.2003) (adopting the Brecht standard for section 2255 motions); United States v. Montalvo, 331 F.3d 1052, 1057 (9th Cir.2003) (same); Peck v. United States, 106 F.3d 450, 456 (2d Cir.1997) (same).
We need not decide this issue here, however, because Owen is not entitled to relief under either standard. Owen’s lack of counsel at his arraignment was plainly harmless beyond a reasonable doubt. As noted above, because Owen pleaded not guilty and requested a jury trial, he did not waive any rights at the arraignment, and he was left free to enter into subsequent plea negotiations if he so desired. J.A. 420-21. And, once appointed, Owen’s counsel had over three months to prepare for trial, because the district court granted his motion for a continuance. S.J.A. 4. Owen’s sole plausible contention of prejudice is that his counsel’s pre-trial motion to dismiss was denied as untimely, because the fifteen-day deadline for pre-trial motions imposed at arraignment had lapsed before counsel was appointed. S.J.A. 4. However, Owen suffered no prejudice from the untimely filing of this motion, because the district court fully examined the merits of the motion and explicitly grounded its decision to deny the motion on its conclusion that the motion was legally meritless. 2d S.J.A. 19 (“In some other context, it might be necessary to relax the 15-day limitation period mandated by the Pretrial Order for a Defendant proceeding pro se during the 15-day period in question. Where, as here, Defendant’s motion is unfounded as a matter of law ... such relaxation is ill-advised.”). Owen has made no other showing that his counsel’s ability to file motions or present his case was in any way hampered by his lack of counsel at arraignment. As the government urges, Owen’s lack of counsel and the subsequent delay before the appointment of his counsel thus had no discernible influence whatsoever on the proceedings. Therefore, the denial of counsel here was harmless beyond a reasonable doubt, and the district court correctly denied Owen’s section 2255 motion on this issue.
CONCLUSION
The judgment of the district court is affirmed.
AFFIRMED.
A presentence report prepared after Owen's conviction calculated his actual net worth at $81,300 and his monthly income at $2278. J.A. 345.
