   MEMORANDUM

Luis Aurelio Perez-Romero, a native and citizen of Mexico, petitions for review of the Board of Immigration Appeals’ (“BIA”) order dismissing his appeal from an immigration judge’s decision denying his motion to suppress evidence and terminate proceedings, and ordering him removed. We have jurisdiction under 8 U.S.C. § 1252. We review de novo questions of law, and review for substantial evidence the agency’s factual findings. Aguilar Gonzalez v. Mukasey, 534 F.3d 1204, 1208 (9th Cir.2008). We deny the petition for review.

The agency did not err in denying Perez-Romero’s motion to suppress his statements in the Form 1-213 and videotaped interview. Contrary to Perez-Romero’s contention, the agency was not required to suppress his statements on the ground that he was not given Miranda warnings before being questioned. See Trias-Hernandez v. INS, 528 F.2d 366, 368-69 (9th Cir.1975) (Miranda warnings are not required in the removal context). Perez-Romero has waived any challenge to the agency’s determination that the questioning officers committed no regulatory violations that would require suppression. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir.1996) (issues not raised in the opening brief are waived).

Substantial evidence supports the agency’s finding that Perez-Romero is removable due to alien smuggling, where the record reflects that he engaged in affirmative acts in aid of a smuggling attempt. See 8 U.S.C. § 1182(a)(6)(E)(i); Aguilar Gonzalez, 534 F.3d at 1208-09. Perez-Romero’s contention that the agency was required to accept his testimony as true in the absence of an explicit adverse credibility determination is foreclosed by Abufayad v. Holder, 632 F.3d 623, 631 (9th Cir.2011).

Perez-Romero’s contention that the BIA failed to address his motion to remand in light of Aguilar Gonzalez is not supported by the record.

PETITION FOR REVIEW DENIED.
