I 've had a DUI 3 years ago and after that I left the US for some family reasons. I visited the US a year later but I didn't go through customs in the city where I have the warrant. Does the warrant still exist? I understand that I cannot use my green card since I have been there for more than 2 years. Will I be able to get a visa? if yes how? If no, what shall I do to fix my status? Thanks.
