MEMORANDUM**

Guillermo Langarica-Rivera appeals from a 71-month sentence imposed follow*845ing his guilty plea to attempted entry after deportation, 8 U.S.C. § 1326.

Langarica-Rivera contends that the district court violated his constitutional rights in making an upward adjustment under U.S.S.G. § 2L1.2(b)(l)(A)(ii) for a crime of violence. This contention is foreclosed by this court’s case law. See United States v. Moreno-Hernandez, 419 F.3d 906, 914-15 n. 8 (9th Cir. 2005) (explaining that a district judge’s enhancement of a sentence, based on the fact of a prior conviction under U.S.S.G. § 2L1.2, does not raise any Sixth Amendment problems).

Because Langarica-Rivera was sentenced under the then-mandatory Sentencing Guidelines, and we cannot reliably determine from the record whether the sentence imposed would have been materially different had the district court known that the Guidelines were advisory, we remand to the sentencing court to answer that question, and to proceed pursuant to United States v. Ameline, 409 F.3d 1073, 1084 (9th Cir. 2005) (en banc). See Moreno-Hernandez, at 915-16 (extending Ameline’s limited remand procedure to cases involving non-constitutional Booker error).
