You are a Canadian citizen visiting US Do you need to return to Canada to marry a US Citizen?

If you are talking about getting married in Canada, then no paperwork is needed. In the US a fiancee's visa, which takes four months to get, is required.  

Answer

nope.. you can get married but you won't be able to work. I AM LEGALLY married to an American man and i am Canadian. I got married to him on a visit last fall... right now, however we are living apart dealing with some of our own issues as to where to live. You can be married but you may not be able to work. As a Canadian you can visit up to 181 days without losing your medical plan back in Canada. Think about all the old ladies that live in Canada during the summer, and Florida in the winter....... they can visit, they just can't work legally.
