Hector Martinez-Hernandez (“Martinez”) appeals his conviction for possession with intent to distribute less than 50 kilograms of marijuana, a violation of 21 U.S.C. § 841.

Martinez’s sole argument on appeal is that a Border Patrol agent lacks authority to conduct a vehicle stop based on a reasonable suspicion of a non-immigration offense. This argument is foreclosed by our *335 decision in United States v. Perkins, 352 F.3d 198 (5th Cir. 2003), cert. denied, 541 U.S. 980, 124 S.Ct. 1894, 158 L.Ed.2d 480 (2004). Martinez concedes that the issue is foreclosed, but he raises it to preserve the matter for further review.

The judgment of the district court is AFFIRMED.
