For starters, Kenny, he would be a she.
I'm married to a UK person, so had to wait for their greencard to come through.
I agree with B2N2 on the minimum requirements. As for my experience, I took the first job I was offered upon getting the greencard, working as a shop assistant in an antique mall. Within 2 months I'd moved to a Part 135 (charter) operator, flew for them for 3 years. I now fly Part 91 and believe it is the best job I will ever have, no matter what I do in the future, I have landed fairly & squarely on my feet. But, and this is the kicker for you, I already had 5000+ hours with a couple of type ratings, so was not restricted from that perspective.
I have friends locally who are slaving away, instructing and trying to build hours to get to the 1200hr mark, and other friends who have over 1200hrs, but the charter market is so slow just now, they are getting about 1 flight every two months, and living on umeployment benefit, or anything else they can get.
On the other hand, another friend with 2500hrs already has a Citation type rating (no, he didn't pay for it himself) and has just got a job flying a King Air. He has a fantastic attitude and must have interviewed really well. It really is the luck of the draw.
I think what it boils down to, is stick tight where you are for a couple of years, build up the hours, if your wife can be patient, then come over with at least 3000hrs under your belt. That will give you a much better starting point from which to look for work.
