I got a dui about a year ago and did not go to the court because I went to mexico and when the court date came up I was not let in by the border patrol and now I'm want to get my papers but don't know if I'm going to get denied what do you think I can do thank you

You should consult with an experienced immigration attorney, in that you likely have a judgment against you in absentia. The conviction and the possible ground of inadmissibilty must be reviewed to see if you need and qualify for a waiver.

Good luck.
