Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Raymond Edward Chestnut seeks to appeal the criminal judgment entered on May 18, 2007, following his guilty to one count of conspiracy to distribute cocaine base, in violation of 21 U.S.C. § 846 (2006), and one count of using and carrying a firearm during and in relation to, and possessing a firearm in furtherance of, a drug trafficking crime, in violation of 18 U.S.C. § 924(c) (2006). 1 The Government has *231 moved to dismiss the appeal as untimely. We grant the Government’s motion and dismiss the appeal.

In criminal cases, a defendant must file his notice of appeal within fourteen days after the entry of judgment. 2 With or without a motion, upon a showing of excusable neglect or good cause, the district court may grant an extension of up to thirty days to file a notice of appeal. Fed. R.App. P. 4(b)(4); United States v. Reyes, 759 F.2d 351, 353 (4th Cir. 1985). Appeal periods are not jurisdictional in criminal cases, but are court-prescribed “claims-processing rules” that do not affect this court’s subject matter jurisdiction. See Rice v. Rivera, 617 F.3d 802, 810 (4th Cir. 2010) (stating that non-statutory claim-processing rules are not jurisdictional); United States v. Urutyan, 564 F.3d 679, 685 (4th Cir. 2009) (“[T]he non-statutory time limits in Appellate Rule 4(b) do not affect subject matter jurisdiction.”). However, we may still enforce the appeal period when the Rule 4(b) time bar is invoked by the Government or sua sponte when judicial resources or administration are implicated or the delay in noting the appeal has been inordinate. United States v. Mitchell, 518 F.3d 740, 744, 750 (10th Cir. 2008).

The district court entered the criminal judgment on May 18, 2007. Chestnut filed his notice of appeal in April 2013, nearly six years beyond the appeal period, and he failed to obtain an extension of the appeal period. Accordingly, we grant the Government’s motion to dismiss and dismiss the appeal. Chestnut’s motions for appointment of counsel, for a transcript at Government expense, for bail or release pending appeal, and to expedite are denied. We also deny Chestnut’s request to dismiss the Government’s motion to dismiss. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED.
