I'm a US citizen getting married to a Canadian, and because she has job obligations in Canada until June, I'd like to move to Ontario until that time. However, I'd have to commute at least several days per week to my job in the US. After June we'd be moving to the US. I need to find out if this is possible to do this without any special visa. It seems pointless to apply for permanent residency, since the application would not even get processed before we move to the US. Can I live in Canada temporarily and commute to the US with just a passport?
