To file an appeal, you start by filing a notice of appeal with the clerk of the court where the case was tried. This should be done within ten days after the district court enters the judgment of conviction or after the government files a notice of appeal. The ten-day time limit is strict and jurisdictional. If you miss this deadline, you may, within thirty days after the ten-day period, file a motion for leave to file a late notice of appeal based on excusable neglect.
