DUI - Immigration Consequences and International Travel
It is a common perception that a conviction for impaired driving, over 80 (DUI) or refuse breath sample will impede your ability for international travel. Firstly, the only country where there might be a concern is the USA. However, we have been practicing law for 35 years and we have never seen a client denied entry to the United States for a first or for that matter subsequent conviction for any of the above noted charges. We obviously cannot predict what the position of Homeland Security in the United States will be going forward, but as of the time of writing traveling anywhere should not be an issue.
However, the reverse is not true. If an American is convicted of the Impaired, driving, over 80 (DUI) or fail or refuse to provide a breath sample he/she will have to wait a period of 10 years before Canadian immigration will permit entry. This causes extreme hardship for those that have family and property in Canada.
You should also be aware that a pardon (now called record suspension in Canada) is not recognized by the United States.
