My colleagues are correct, you need to seek the advice of an experienced immigration lawyer right away. And do him/her and yourself a favor when you set that consultation - bring all your DUI disposition paperwork, and sentencing documents, as well as all documentation relative to your current immigration status in this Country. That will help expedite things. Good luck.
Informal probation usually does not restrict travel, so the court doesn't mind if you travel. I haven't found any European country that excludes tourists due to DUI conviction or probation. Canada will be very difficult to visit.
