U.S. Citizen Marrying Canadian on N-1 Visa

[AgnesBurdell]

I am a U.S. citizen by birth. My fiance is from Canada and has lived in the states legally for over a decade. We are planning a large wedding for May of next year, but his NAFTA visa expires in June.

My understanding is:
1) We cannot start the paperwork for his marriage-based green card until we are already married.
2) The paperwork takes 3-6 months to be processed.
3) He will be ineligible to renew his NAFTA visa once we start the process for his marriage-based green card.

First off, is my understanding correct? Secondly, how do we ensure that his green card is approved before his visa expires?

Thanks
A.B.

Your understanding is correct.

If you start the adjustment of status process in May and want things wrapped up by June... I don't see it happening.
