JEFFERSON B. SESSIONS III, Attorney

                Respondent.

                     On Petition for Review of an Order of the
                         Board of Immigration Appeals

                              Submitted August 15, 2018**

Before:      FARRIS, BYBEE, and N.R. SMITH, Circuit Judges.

      Miguel Guttierez-Ruiz, 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 application for asylum, withholding of

removal, and relief under the Convention Against Torture (“CAT”). Our

             The panel unanimously concludes this case is suitable for decision
without oral argument. See Fed. R. App. P. 34(a)(2).
jurisdiction is governed by 8 U.S.C. § 1252. We review de novo questions of law

and constitutional claims. Roman-Suaste v. Holder, 766 F.3d 1035, 1038 (9th Cir.

2014). We deny in part and dismiss in part the petition for review.

      In his opening brief, Guttierez-Ruiz fails to challenge the agency’s denial of

CAT relief. See Corro-Barragan v. Holder, 718 F.3d 1174, 1177 n.5 (9th Cir.

2013) (failure to contest issue in opening brief resulted in waiver).

      We lack jurisdiction to consider Guttierez-Ruiz’s contentions as to the

validity of his criminal conviction because these claims are impermissible

collateral attacks upon his state court conviction. See Ramirez-Villalpando v.

Holder, 645 F.3d 1035, 1041 (9th Cir. 2011) (holding that petitioner could not

collaterally attack his state court conviction on a petition for review of a BIA

decision).

      We also lack jurisdiction to consider Guttierez-Ruiz’s contentions as to his

eligibility for a U-visa and whether his conviction constitutes a particularly serious

crime because Guttierez-Ruiz failed to raise these issues to the BIA. See Barron v.

Ashcroft, 358 F.3d 674, 677-78 (9th Cir. 2004) (court lacks jurisdiction to review

claims not presented to the agency).

      PETITION FOR REVIEW DENIED in part; DISMISSED in part.
