Carlos Lorenzo Chacon-Arviso challenges the substantive reasonableness of his 60-month sentence, imposed after he pleaded guilty to illegally reentering the United States after deportation, in violation of 8 U.S.C. § 1326. Although post- Booker, the Sentencing Guidelines are advisory only, and a properly preserved objection to an ultimate sentence is reviewed for reasonableness under an abuse-of-discretion standard, the district court must still properly calculate the advisory Guidelines-sentencing range for use in deciding on the sentence to impose. Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). In that respect, for issues preserved in district court, its application of the Guidelines is reviewed de novo; its factual findings, only for clear error. E.g., United States v. Cisneros-Gutierrez, 517 F.3d 751, 764 (5th Cir. 2008). Chacon does not claim procedural error. Instead, he challenges only the substantive reasonableness of his sentence.

And, because he did not raise in district court the issues presented here, review is only for plain error. E.g., United States v. Peltier, 505 F.3d 389, 391-92 (5th Cir. 2007). Under that standard, he must show a forfeited plain (clear or obvious) error that affected his substantial rights. Puckett v. United States, 556 U.S. 129, 135, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009). If he does so, we have the discretion to correct the error, but should do so only if it seriously affects the fairness, integrity, or public reputation of the proceedings. Id. (Chacon maintains he was not required to object regarding the substantive reasonableness of his sentence but acknowledges our precedent required an objection. He makes this assertion to preserve it for possible future review.)

Chacon contends his sentence is substantively unreasonable because it is greater than necessary to achieve the § 3553(a) sentencing goals, such as claiming illegal reentry is merely “an international trespass” and the sentence “fails to properly reflect Chacon’s personal history and characteristics”. As in this instance, sentences within the properly calculated advisory *949 Guideline sentencing range are presumed reasonable. E.g., United States v. Alonzo, 435 F.3d 551, 554 (5th Cir. 2006).

Chacon claims this presumption should not apply, maintaining the illegal-reentry Guidelines lack an empirical basis. He acknowledges his contention is foreclosed by our precedent, e.g., United States v. Mondragon-Santiago, 564 F.3d 357, 366-67 (5th Cir. 2009), but raises it to preserve it for possible future review. Chacon’s claim otherwise amounts to disagreeing with the court’s assessment of the § 3553(a) sentencing factors; therefore, he fails to rebut the presumption of reasonableness. See, e.g., United States v. Ruiz, 621 F.3d 390, 398 (5th Cir. 2010).

AFFIRMED.
