Esteban Bygoytia-Zuniga (Bygoytia) appeals his 18-month sentence imposed following his guilty plea conviction for being found illegally in the United States following deportation. Bygoytia argues that his sentence is unreasonable, although within the advisory guidelines range, because the Guidelines overstated the seriousness of his offense and failed to take into account the mitigating nature of his cultural assimilation and his motive for returning to the United States.

We review the substantive reasonableness of a sentence for an abuse of discretion. Gall v. United States, 552 U.S. 38, 128 S.Ct. 586, 597, 169 L.Ed.2d 445 (2007). Bygoytia presented his arguments at length in his written objections and personally and through counsel at his sentencing hearing. The district court recognized the hardship of Bygoytia being separated from his family if they remained in the United States but pointed out that Bygoy-tia had lost his legal status in 1987 because he had committed a crime and that he has continued to enter this country illegally since that time. The district court’s comments reflect a familiarity with Bygoytia’s personal history and the nature of his pri- or offenses. Because the district court clearly considered Bygoytia’s argument regarding cultural assimilation, its rejection of the variance on that basis does not render the sentence unreasonable. See United States v. Gomez-Herrera, 523 F.3d 554, 565 (5th Cir.), cert. denied, — U.S. -, 129 S.Ct. 624, 172 L.Ed.2d 617 (2008). Prior to imposing the guidelines sentence, the district court stated that it *941 had considered the information provided, the circumstances of the case, and the goals of the Sentencing Guidelines and § 3553(a).

Because it is within the guidelines range, Bygoytia’s sentence is entitled to a presumption of reasonableness, see United States v. Campos-Maldonado, 531 F.3d 337, 338 (5th Cir.), cert. denied, — U.S. -, 129 S.Ct. 328, 172 L.Ed.2d 236 (2008), and Bygoytia has shown no good reason for us to disturb it. See Gall, 128 S.Ct. at 597.

Bygoytia acknowledges that the two additional arguments that he raises are foreclosed. He argues that the appellate presumption of reasonableness should not apply because U.S.S.G. § 2L1.2 lacked an empirical foundation and that the guidelines range reflected an unwarranted disparity between defendants who can participate in a fast-track program and defendants who cannot. As Bygoytia concedes, we have previously rejected such arguments. United States v. Mondragon-Santiago, 564 F.3d 357, 366 (5th Cir.), cert. denied, — U.S. -, 130 S.Ct. 192, 175 L.Ed.2d 120 (2009); Gomez-Herrera, 523 F.3d at 563.

AFFIRMED.
