MEMORANDUM ***

Seryozha Khachatryan and his wife, Zoya Khachatryan, natives and citizens of Armenia, petition for review of the Board of Immigration Appeals’ (“BIA”) summary affirmance of the immigration judges’s (“IJ”) denial of their application for asylum, withholding of removal and relief under the Convention Against Torture (“CAT”). We have jurisdiction under 8 U.S.C. § 1252 and review for substantial evidence. Hasan v. Ashcroft, 380 F.3d 1114, 1119 (9th Cir. 2004).

Substantial evidence supports the IJ’s decision. Khachatryan’s asylum claim fails because his letter did not expose government corruption, but instead was directed at the corrupt individuals who did not pay for the auto repair service that he provided. See Grava v. INS, 205 F.3d 1177, 1179-81 (9th Cir. 2000). Furthermore, sub*983stantial evidence does not show that Khachatryan’s subsequent beatings and extortion were on account of a protected ground. See Kozulin v. INS, 218 F.3d 1112, 1115-17 (9th Cir. 2000).

Because petitioners do not challenge the IJ’s denial of withholding of removal and CAT relief in their opening brief, the claims are waived. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259 (9th Cir. 1996).

PETITION FOR REVIEW DENIED.
