Does Having A First Offense DWI Automatically Disqualify A Person From Qualifying For US Citizenship?
No, not automatically, though it may give them the right to deny citizenship especially if there is a history of DWI. One offense, though, shouldn't disqualify you from applying. You can find out more about immigration law at uscis.gov if you go to Laws and Regulations.
