Entering Canada with a DUI from the USAJonathan Rands
If you've had a DUI conviction and tried to enter Canada you may have encountered some difficulties in crossing the border.
Canada looks at past criminal history and translates the foreign crime to the Canadian equivalent. In the case of a US DUI conviction then, it's translated to the Canadian offense, with a maximum punishment of 10 years in prison. Even if the DUI conviction is from years ago, it could still give you some problems.
In their article, Entering Canada with a DUI from the USA from CIC News, authors Matt Hendler and Michael Schwartz outline some options for overcoming inadmissibility including Temporary Resident Permits (TRP), Criminal Rehabilitation, and a Legal Opinion Letter and why you need an immigration lawyer to help you do so.
