You should immediately hire an immigration attorney. Your DUI, if it was a deportable offense may render you ineligible to get a green card. I hasten to add that a waiver of the DUI may be available to you. But my main concern is that if you did indeed agreed to a voluntary departure, and then did not leave the U.S. as you promised, you likely now have a warrant of arrest and order of deportation on file. If you now come in contact with DHS, you may be physically removed from this country without further ado based on the outstanding order of removal. I advise you not to file any paperwork with CIS without first hiring an experienced attorney
