Yawo Elesesi Amenuvor, a citizen of Togo, petitions for review of an order of the Board of Immigration Appeals (BIA), which affirmed without opinion an Immigration Judge’s (IJ’s) denial of asylum and related relief.1 Amenuvor challenges the IJ’s adverse credibility determination and argues that his case was not appropriate for an affirmance without opinion.
Initially, we note that Amenuvor’s argument regarding the BIA’s decision to affirm his case without opinion is unreviewable. See Ngure v. Ashcroft, 367 F.3d 975, 981-88 (8th Cir.2004) (finding that BIA’s decision whether to employ affirmancewithout-opinion procedure in particular case is committed to agency discretion and not subject to judicial review).
After careful review of the record, we conclude that the IJ’s decision on Amenuvor’s asylum application is supported by substantial evidence on the record as a whole. See Menendez-Donis v. Ashcroft, 360 F.3d 915, 917-19 (8th Cir.2004) (standard of review). Specifically, the IJ discredited Amenuvor’s testimony about past persecution he suffered, and we defer to that credibility finding because it was supported by specific, cogent reasons for disbelief. See Nyama v. Ashcroft, 357 F.3d 812, 817 (8th Cir.2004) (per curiam) (deference standard). In addition, because Amenuvor failed to meet the burden of proof on his asylum claim, he failed to meet the higher burden for withholding of removal. See Kratchmarov v. Heston, 172 F.3d 551, 555 (8th Cir.1999).
Accordingly, we deny the petition. Amenuvor moved for a stay of deportation before his voluntary-departure period expired, and we therefore deem this court’s grant of his unopposed motion to include a stay of his voluntary-departure period as well. See Rife v. Ashcroft, 374 F.3d 606, 616 (8th Cir.2004).
