MEMORANDUM ***

Tiangang Li petitions for review of the Board of Immigration Appeals’ order summarily affirming the immigration judge’s (“LJ”) denial of his application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). *768 The IJ denied relief because she found Li’s testimony not credible.

1. Substantial evidence supports the IJ’s determination that Li was not credible. See Bassene v. Holder, 737 F.3d 530, 536 (9th Cir. 2013). The IJ permissibly based her adverse credibility determination in part on Li’s testimony that he returned to China several times after his first arrest, which cast doubt on his claim that he feared he would be persecuted if he returned there. See Loho v. Mukasey, 531 F.3d 1016, 1018 (9th Cir. 2008). The IJ was not compelled to accept Li’s explanation that he lost all hope in the govern-' ment only after his second detention and interrogation. See Zamanov v. Holder, 649 F.3d 969, 974 (9th Cir. 2011).

Additionally, the IJ did not err in considering Li’s failure to corroborate certain aspects of his testimony in reaching her adverse credibility determination. See Lai v. Holder, 773 F.3d 966, 976 (9th Cir. 2014). Nor did the IJ err in disregarding Li’s copy of an email purporting to confirm his church attendance in Singapore, or in rejecting his explanations for his failure to corroborate his testimony about mailing religious literature to China or attending church in San Jose.

In the absence of credible testimony, Li fails to establish that he is eligible for asylum or withholding. See Jie Cui v. Holder, 712 F.3d 1332, 1337-38 & n. 3 (9th Cir. 2013); Farah v. Ashcroft, 348 F.3d 1153, 1156 (9th Cir. 2003).

2. The IJ also found that Li had.not presented credible testimony that he would be tortured upon his return to China. Li did not address his eligibility for CAT relief in his opening brief and therefore waived any objection to the IJ’s denial of this claim. See Me Cui, 712 F.3d at 1338 n. 3.

PETITION DENIED.
