Maria Nicolasa Salinas appeals the sentence imposed following her guilty plea to transporting an illegal alien for private financial gain. Citing United States v. Booker, - U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), Salinas argues that the six-level increase she received pursuant to U.S.S.G. § 2K2.1(b)(5) violated her Sixth Amendment rights. As Salinas did not raise this claim in the district court, our review is for plain error. See United States v. Mares, 402 F.3d 511, 520 (5th Cir. 2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517). Salinas’s argument fails to survive review under this standard because she has not shown that any Booker error affected her substantial rights. See id. at 522.

AFFIRMED.
