Actually Randy Quaid's wife Evi was in fact a Canadian citizen.  This was so  because her father was a Canadian citizen at the time of her birth,  She received her citizenship confirmation in 2011.

She then sponsored her husband's application for permanent residence but it was refused and he was ordered to leave Canada.  The couple were arrested at the U.S./Canada border in Vermont at the Highgate Springs port of entry on October 9, 2015 when re-entering the US.

They were released from a Vermont jail  a week after they were arrested as Superior Court Judge Alison Arms who ruled there was no probable cause to hold the couple in Vermont upon reviewing the California extradition documents and finding them deficient.
