In most circuits, convictions in criminal cases are not considered sufficiently final to permit the initiation of deportation proceedings if an appeal is pending or they are still subject to appeal. Matter of Polanco, 20 I. & N. Dec. 894 (BIA 1994). This is not true in the Fifth or Seventh Circuits. See Moosa v. INS,171 F.3d 994 (5th Cir. 1999); Renteria-Gonzales v. INS, 322 F.3d 804 (5th Cir. 2002); Montenegro v. Ashcroft, 355 F.3d 1035, 1037 (7th Cir. 2004).
