Jessica Garay appeals the sentence imposed following her guilty plea to trans *819 portation of undocumented aliens. She argues that her sentence is unreasonable as a matter of law because our post-Booker 1 rulings have effectively reinstated the mandatory sentencing guidelines regime. Garay correctly concedes that this claim is foreclosed by our precedent and raises it only to preserve its further review by the Supreme Court. See Rita v. United States, — U.S. -,---, 127 S.Ct. 2456, 2462-66, 168 L.Ed.2d 203 (2007); United States v. Alonzo, 435 F.3d 551, 554 (5th Cir. 2006).

AFFIRMED.
