OPINION OF THE COURT

On March 4, 2003, Raymond Leonor pled guilty to a single count information charging him with knowingly and intentionally possessing more than five hundred grams of cocaine with the intent to distrib *967 ute, in violation of 21 U.S.C. §§ 841(a)(1) and 841(b)(1)(B). At sentencing on June 13, 2003, the District Court determined that Leonor’s guideline range was 51 to 63 months of incarceration, which was compressed to 60 to 63 months as a result of the mandatory statutory minimum of five years given the nature of the offense. Although Leonor’s counsel raised the possibility of moving for a “safety valve” downward adjustment pursuant to 18 U.S.C. § 3553(f)(l)-(5), a recent ruling by this Court foreclosed that possibility. See United States v. Boddie, 318 F.3d 491, 494 (3d Cir. Jan.28, 2003). The District Court sentenced Leonor to 60 months imprisonment and a four-year term of supervised release.

After filing a timely notice of appeal, Leonor’s counsel moved to withdraw pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). 1 In Anders, the Supreme Court held that the “constitutional requirement of substantial equality and fair process” necessitates that appellant’s counsel vigorously act as an advocate for the defendant. Id. at 744, 87 S.Ct. 1396. Thus, counsel’s

role as advocate requires that he support his client’s appeal to the best of his ability. Of course, if counsel finds his case to be wholly frivolous, after a conscientious examination of it, he should so advise the court and request permission to withdraw. That request must, however, be accompanied by a brief referring to anything in the record that might arguably support the appeal.

Id. In United States v. Youla, 241 F.3d 296, 300 (3d Cir. 2001), we reiterated that an Anders brief must demonstrate that counsel has “thoroughly examined the record in search of appealable issues,” and it must “explain why the issues are frivolous.” Thus, our inquiry is twofold: (1) whether counsel adequately fulfilled the requirements of Anders; and (2) “whether an independent review of the record presents any nonfrivolous issues.” Id. (citing United States v. Marvin, 211 F.3d 778, 780 (3d Cir. 2000)); see also Anders, 386 U.S. at 744, 87 S.Ct. 1396 (explaining that the court must proceed, “after a full examination of all the proceedings, to decide whether the case is wholly frivolous”). If review fails to reveal any non-frivolous issues, the Court “may grant counsel’s request to withdraw and dismiss the appeal.” Anders, 386 U.S. at 744, 87 S.Ct. 1396.

We conclude that counsel fulfilled the requirements of Anders with respect to Leonor’s conviction. 2 Counsel asserted that there were no deficiencies with regard to Leonor’s guilty plea colloquy. Our review of the appended plea agreement and colloquy verifies that Leonor’s plea complied with both the requirements of Federal Rule of Criminal Procedure 11 and Boykin v. Alabama, 395 U.S. 238, 89 S.Ct. 1709, 23 L.Ed.2d 274 (1969).

Our own independent review of the record reveals, however, that Leonor’s sentence was imposed before the Supreme Court’s decision in United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). At first blush, this suggests that there may be a possibility that Leonor might benefit if he were re-sentenced under an advisory sentencing scheme. Leonor, however, was sentenced to the mandatory minimum of sixty months, see 21 U.S.C. § 841(b)(1)(B), and a remand for resentencing cannot result in a *968 lighter sentence. Accordingly, there is no basis for vacating Leonor’s sentence. Indeed, Leonor may have anticipated as much as he did not respond to this Court’s inquiry regarding the applicability of Booker.

Accordingly, we will grant counsel’s motion to withdraw and we will affirm Leonor’s conviction and sentence. We certify that the issues presented in the appeal lack legal merit and thus do not require the filing of a petition for writ of certiorari with the Supreme Court.3d Cir. LAR 109.2(b).
