The Federal Public Defender appointed to represent Uriel Valencia-Torres has moved for leave to withdraw and has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and United States v. Flores, 632 F.3d 229 (5th Cir. 2011). Valencia-Torres has filed a response. The record is not sufficiently developed 'to allow us to make a fair evaluation of Valencia-Torres’s claims of ineffective assistance *295 of counsel; we therefore decline to consider the claims without prejudice to collateral review. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir.), cert. denied, — U.S.-, 135 S.Ct. 123, 190 L.Ed.2d 94 (2014).

We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Valencia-Torres’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, the motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
