¶1SUMMARY ORDER
¶2Chun Hui Weng, a native and citizen of the People’s Republic of China, seeks review of a October 31, 2005 order of the BIA, affirming the February 9, 2005 decision of Immigration Judge (“IJ”) Aan L. Page, which denied his application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). In re Chun Hui Weng, No. A97 391 305 (B.I.A. Oct. 31, 2005), aff'g No. A97 391 305 (Immig. Ct. N.Y. City Feb. 9, 2005). We assume the parties’ familiarity with the underlying facts and procedural history in this case.
¶3When the BIA summarily affirms the decision of the IJ without issuing an opinion, see 8 C.F.R. § 1003.1(e)(4), we review the IJ’s decision as the final agency determination. See, e.g., Twum v. INS, 411 F.3d 54, 59 (2d Cir.2005); Yu Sheng Zhang v. U.S. Dep’t of Justice, 362 F.3d 155, 159 (2d Cir.2004). We review the agency’s factual findings, including adverse credibility determinations, under the substantial evidence standard, treating them as “conclusive unless any reasonable adjudicator would be compelled to conclude to the contrary.” 8 U.S.C. § 1252(b)(4)(B); see also Shu Wen Sun v. BIA, 510 F.3d 377, 379 (2d Cir.2007). Nevertheless, “the fact that the [agency] has relied primarily on credibility grounds in dismissing an asylum application cannot insulate the decision from review.” Ramsameachire v. Ashcroft, 357 F.3d 169, 178 (2d Cir.2004). An adverse credibility determination must be based on “specific, cogent reasons” that “bear a legitimate nexus” to the finding. Secaida-Rosales v. INS, 331 F.3d 297, 307 (2d Cir.2003).
¶4Upon review of the administrative record, we find that substantial evidence supports the IJ’s adverse credibility determination. The IJ properly relied on Weng’s inconsistent accounts of his whereabouts during his father’s arrest for practicing Falun Gong. See Biao Yang v. Gonzales, 496 F.3d 268, 272 (2d Cir.2007). Indeed, during his credible fear interview, Weng claimed that he was hiding at his house watching the police arrest his father; however, in his asylum application and at his hearing he stated that he was not at home during his father’s arrest.
¶5Moreover, the agency did not err in relying on these inconsistent statements even though they arose in the context of Weng’s credible fear interview. Where an IJ rests an adverse credibility determination on statements made during such an interview,
¶6The IJ also reasonably questioned the authenticity of the certificates of Falun Gong membei’ship that Weng submitted into evidence. We will reject an IJ’s deduction “only when there is a complete absence of probative facts to support it— that is, when the speculation is ‘bald.’ ” Siewe v. Gonzales, 480 F.3d 160, 168 (2d Cir.2007). However, the “speculation that *391inheres in inference is not ‘bald’ if the inference is made available to the factfin-der by record facts, or even a single fact, viewed in the light of common sense and ordinary experience.” Id. at 168-69. Here, the IJ reasonably noted that despite Weng’s claim that his father was an advanced Falun Gong leader and that he was not an advanced practitioner, the certificates contained virtually identical language indicating that both Weng and his father had completed advanced Falun Gong work. See Siewe, 480 F.3d at 168. Moreover, no reasonable fact-finder would have been compelled to accept Weng’s ultimate explanation where he only provided said explanation after extensive questioning without explanation. See Majidi, 430 F.3d at 80-81. Finally, we note that Weng has waived any challenge to the IJ’s finding that he failed to submit sufficient corroborating evidence to rehabilitate his testimony that he is a Falun Gong practitioner. See Yueqing Zhang v. Gonzales, 426 F.3d 540, 541 n. 1, 545 n. 7 (2d Cir.2005).
¶7Ultimately, because a reasonable fact-finder would not be compelled to conclude to the contrary, and because there were no errors of sufficient importance to cast doubt on the neutrality of the factfinding process, the IJ’s adverse credibility determination was supported by substantial evidence.
¶8For the foregoing reasons, the petition for review is DENIED. As we have completed our review, any stay of removal that the Court previously granted in this petition is VACATED, and any pending motion for a stay of removal in this petition is DISMISSED as moot. Any pending request for oral argument in this petition is DENIED in accordance with Federal Rule of Appellate Procedure 34(a)(2), and Second Circuit Local Rule 34(b).
¶9. Although we recently held that the REAL ID Act, Pub.L. No. 109-13, 119 Stat. 231 (2005), abrogated significant portions of Secaida-Ro-sales for asylum petitions filed after May 11, *3902005, see Xiu Xia Lin v. Mukasey, 534 F.3d 162, 167 (2d Cir.2008), Weng's application for relief was filed in December 2003 well before the May 2005 effective date of the REAL ID Act. Moreover, the proposition that an adverse credibility determination must be based on "specific, cogent reasons" that “bear a legitimate nexus” to the credibility determination was not affected by our decision in Xiu Xia Lin. See Balachova v. Mukasey, 547 F.3d 374, 380 n. 2 (2nd Cir.2008).
¶10. Although we have not explicitly decided whether the concerns potentially present in airport interviews, which take place immediately upon the alien’s arrival in the United States, are present in equal force at credible fear interviews, which generally take place several days or weeks later, we need not determine the precise degree of caution to be afforded in evaluating such interviews in this case because a review of the record of Weng’s credible fear interview reveals that it represents a "sufficiently accurate record” of his statements under the factors assessed to determine the accuracy of the more strictly reviewed airport interview. See Diallo v. Gonzales, 445 F.3d 624, 631-32 (2d Cir.2006).
¶11. Although the IJ may have erred in relying on Weng's lack of knowledge regarding Falun Gong and further in questioning the authenticity of Weng’s national identification card, see Rizal v. Gonzales, 442 F.3d 84, 90 (2d Cir.2006) (determining that an applicant's lack of doctrinal knowledge cannot be held against an applicant who does not claim to be an expert in or have a deep understanding of the religion in question); see also Secaida-Rosales, 331 F.3d at 310 (concluding that an applicant’s ability to obtain identification documents in his home country while in hiding for fear of persecution is itself not "a valid, cogent reason for a negative credibility finding”), we find that remand is unnecessary. See Xiao Ji Chen v. U.S. Dep’t of Justice, 471 F.3d 315, 338-40 (2d Cir.2006) (holding that remand is not required where substantial evidence supports the IJ’s error-free findings supporting the adverse credibility determination and where the Court can confidently predict that the agency would make the same decision were the petition remanded).
