OPINION

Celso Ramirez-Anzua seeks to appeal his conviction for conspiracy to possess with intent to distribute marijuana, in violation of 21 U .S.C.A. § 846 (West 1999). Ramirez-Anzua’s counsel has filed a brief pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), asserting there are no meritorious issues for appeal. Advised of his right to file a pro se supplemental brief, Ramirez-Anzua has not done so.

Ramirez-Anzua signed a written plea agreement in which he agreed to waive his right to appeal his conviction or sentence, except for claims of ineffective assistance of counsel or prosecutorial misconduct. A waiver of appeal provision in a valid plea agreement is enforceable if it results from a knowing and intelligent decision to forgo an appeal. United States v. Attar, 38 F.3d 727, 731 (4th Cir. 1994); United States v. Wiggins, 905 F.2d 51, 53 (4th Cir. 1990). A waiver is ineffective if the district court fails to question the defendant about it, United States v. Wessells, 936 F.2d 165, 167-68 (4th Cir. 1991), unless other evidence in the record shows that the waiver was informed and voluntary, United States v. Davis, 954 F.2d 182, 186 (4th Cir. 1992). We review de novo the validity of a waiver. United States v. Marin, 961 F.2d 493, 496 (4th Cir. 1992).

Here, Ramirez-Anzua signed the plea agreement containing the waiver provision. The Government summarized the plea agreement at the Fed.R.Crim.P. 11 hearing. An interpreter was present at the hearing to translate the proceeding into Spanish, Ramirez-Anzua’s native language. In response to the magistrate judge’s inquiry, Ramirez-Anzua agreed that the right to appeal the conviction and sentence was expressly waived in the plea agreement. He said that he was happy with the services of his counsel and that he had heard and understood the Rule 11 proceeding. On this record, we conclude that Ramirez-Anzua’s waiver was knowingly and intelligently made. As the only claims counsel asserts in his brief involve sentencing, they are barred by RamirezAnzua’s valid waiver of his appeal rights and we dismiss the appeal on that basis. United States v. Brown, 232 F.3d 399, 402-03 (4th Cir. 2000).

We have examined the entire record in this cáse in accordance with the requirements of Anders, and find no meritorious issues for appeal. We therefore dismiss the appeal. This Court requires that counsel inform his client, in writing, of his right to petition the Supreme Court of the United States for further review. If the client requests that a petition be filed, but counsel believes that such a petition would *147 be frivolous, then counsel may move in this Court for leave to withdraw from representation. Counsel’s motion must state that a copy thereof was served on the client.

We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the Court and argument would not aid the decisional process.

DISMISSED.
