MEMORANDUM **

Hao Tuan Diep, a native and citizen of Vietnam, petitions for review of the Board of Immigration Appeals’ order dismissing his appeal from an immigration judge’s decision denying his application for protection under the Convention Against Torture (“CAT”). We have jurisdiction under 8 U.S.C. § 1252. We review for substantial evidence, Silaya v. Mukasey, 524 F.3d 1066, 1070 (9th Cir. 2008), and we deny the petition for review.

Diep did not testify to having experienced any physical harm in Vietnam. After release from prison, his father, a former officer in the South Vietnamese army, remained in Vietnam for eight years without incident. Neither his brother nor his mother experienced any harm during their visits to Vietnam. Substantial evidence supports the agency’s denial of CAT protection because Diep failed to establish it is more likely than not he will be tortured *576 if he returns to Vietnam. See Santos-Lemus v. Mukasey, 542 F.3d 738, 747-48 (9th Cir. 2008).

PETITION FOR REVIEW DENIED.
