PRESENT: JON O. NEWMAN, ROBERT D. SACK, and DEBRA ANN LIVINGSTON, Circuit Judges.
SUMMARY ORDER
Moribine Kourouma, a native and citizen of Guinea, seeks review of an October 23, 2008 order of the BIA, affirming the April 16, 2007 decision of Immigration Judge *168 (“IJ”) Sandy Horn, which denied his application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). In re Moribine Kourouma, No. A073 697 669 (B.I.A. Oct. 23, 2008), aff'g No. A073 697 669 (Immig. Ct. N.Y. City Apr. 16, 2007). We assume the parties’ familiarity with the underlying facts and procedural history in this case.
Because the BIA adopted and supplemented the IJ’s decision, we review both decisions. See Yan Chen v. Gonzales, 417 F.3d 268, 271 (2d Cir.2005). The applicable standards of review are well-settled. 8 U.S.C. § 1252(b)(4)(B); see also Corovic v. Mukasey, 519 F.3d 90, 95 (2d Cir.2008).
Substantial evidence supports the agency’s adverse credibility determination. In his initial application, Kourouma stated only “I have been [sic] object of many threatened [sic] and was once arrested.” In an amended asylum application he submitted prior to his merits hearing, however, he stated that he had been detained for almost two years, during which time he was beaten and tortured with electric shocks. The agency reasonably found that Kourouma’s omission of these material allegations undermined his credibility. See Dong v. Ashcroft, 406 F.3d 110 (2d Cir.2005). Moreover, no reasonable fact-finder would have been compelled to accept Kourouma’s explanation that this omission was a simple oversight. See Majidi v. Gonzales, 430 F.3d 77, 81 (2d Cir.2005). The IJ also reasonably relied on his observations of Kourouma’s demeanor during his merits hearing to find that he was not credible. See id. at 81 n. 1. Having called Kourouma’s credibility into question, the IJ was entitled to note the absence of corroborating evidence that could have rehabilitated his testimony. See Biao Yang v. Gonzales, 496 F.3d 268, 274 (2d Cir.2007).
Ultimately, substantial evidence supports the agency’s adverse credibility determination. See Shu Wen Sun v. BIA, 510 F.3d 377, 379 (2d Cir.2007). Thus, we find no error in the agency’s denial of Kourouma’s application for asylum, withholding of removal, and CAT relief. See Paul v. Gonzales, 444 F.3d 148, 156 (2d Cir.2006); Xue Hong Yang v. U.S. Dep’t of Justice, 426 F.3d 520, 523 (2d Cir.2005).
For 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).
