Hi,

I'm not an immigration attorney but I am a Canadian citizen who moved to the US to marry my wife. I would suggest looking into the K-1 visa if you are sure that you want to go this route. Don't get married in the meantime; the K-1 is a fiance(e) visa that allows you to move to the US, get married within three months of entry, and then immediately adjust status to permanent resident. This avoids the appearance that the marriage was purely for immigration convenience, since everything is above-board and approved first.

Getting married first would require you to apply for a CR-1 immigration visa, which is a similar process, but neither is exactly "quick" (I would expect a year or more on average).

I would take a look at http://www.visajourney.com/ as they have a ton of good advice for family class immigration. Good luck!

Depending on what she does for work she could come to the US immediately on a TN visa. If she does a fiance visa or a marriage visa it will take 6-12 months before getting work authorization.
