I have spent the last year in the usa after moving there upon completion of my degree in australia. I am now flight instructing for an aviation college in the northeast, and am really glad i made the move.
It was hard starting out, the biggest obstacle being the big financial side of converting all my licenses over to the us standard.
I completed a us instructor rating over here which was relatively simple, and the us is in such an economic boom at the moment that you can almost pick and choose a flight instructor position anywhere, seriously.
The majors are hiring the most pilots they ever have, which is spilling down to the regionals and the flying schools. All regionals are hiring alot of pilots to make up for those going to the majors. People are being picked up with around 1000hrs total time and 150-200 multi, some going straight into Embraers and Canadairs.
So long as you have the right to work in the usa, i.e green card or working permit, i'd say go for it, the bullet, you won't be dissapointed. Alot of flying work around,(twin work is very sought after, as you'd expect, so that will be a little more difficult to find), and alot of progression to the regionals/majors.
Just make sure you have some savings behind you to start out!
If you've got any more questions, let me know
