People v. Nguyen, 80 P.3d 903 (Colo.App., 2003), (a judge has no affirmative obligation to make an advisement regarding the immigration consequences, but once a judge chooses to engage in such an advisement, the advice given must be non-negligent and proper, if the advice lulls the defendant into a false sense of security, the plea should be withdrawn.) Thanks to Jeff D. Joseph.
