OPINION OF THE COURT

Jonathan Berberena, pursuant to a written plea agreement, pled guilty to all five *435 counts set forth in an indictment filed against him: conspiracy to distribute and possession with intent to distribute cocaine base, possession with intent to distribute cocaine and possession with intent to distribute cocaine and cocaine base within one thousand feet of a school. After reading his presentence report, but prior to being sentenced, Berberena moved to withdraw his guilty plea. That motion was denied. He was then sentenced to 384 months imprisonment, five years of supervised release and a special assessment of $500. 1

After reviewing the record and caselaw, Berberena’s counsel now moves to withdraw pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). In Anders, the Supreme Court stated that the “constitutional requirement of substantial equality and fair process” means that appellate counsel must act as an advocate for the defendant. 386 U.S. 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. As we explained in United States v. Youla, 241 F.3d 296, 300 (3d Cir. 2001), the 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.” Accordingly, 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 nonfrivolous issues, the court “may grant counsel’s request to withdraw and dismiss the appeal.” Anders, 386 U.S. at 744, 87 S.Ct. 1396.

After considering counsel’s Anders brief, we are satisfied that she thoroughly examined the record for issues of arguable merit and fulfilled the requirements of Anders. Counsel correctly observed that Berberena’s plea of guilty limited the issues he is entitled to challenge on appeal to the District Court’s jurisdiction, the validity of the guilty plea, and the legality of the sentence. United States v. Broce, 488 U.S. 563, 570-75, 109 S.Ct. 757, 102 L.Ed.2d 927 (1989). As Berberena’s counsel noted, there is no basis for disputing the District Court’s jurisdiction.

With respect to the validity of Berberena’s guilty plea, counsel fully satisfied her obligation under Anders. She considered not only whether the guilty plea proceeding complied with the requirements of Boykin v. Alabama, 395 U.S. 238, 89 S.Ct. 1709, 23 L.Ed.2d 274 (1969), but also addressed each of the requirements of Federal Rule of Criminal Procedure 11. Berberena’s counsel also properly addressed his motion to withdraw his plea upon learning of the sentence that would result from his presentence report, and noted that the District Court properly denied that motion in light of United States v. Harris, 44 F.3d 1206, 1210 (3d Cir. 1995).

Berberena’s sentencing was also conscientiously examined by his appellate counsel. We agree that the District Court did *436 not err in calculating the criminal history score. Our review of the record confirms that the District Court had sufficient evidence to support its computation of Berberena’s criminal history score.

Counsel advised Berberena of his intention to file an Anders brief and that Berberena was entitled to file a pro se brief. 2 Berberena filed a brief pro se which conformed to the assessment of his case made by his attorney in her Anders brief. 3

In sum, we agree with counsel’s assessment of Berberena’s appeal. Our own independent review of the record fails to reveal any nonfrivolous issues for appeal.

Accordingly, we will grant counsel’s motion to withdraw and affirm the judgment of the District Court entered on May 1, 2003. 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).
