Very , very difficult to do these days , it was hard enough to do before 9/11 let alone now. Letsbe is on the money with his reply but the marriage route is not so simple as all sorts of proof and checks are now required ( joint bank accounts , rent contracts etc. ) Even if you went in as a wetback you still have to prove eligibility to work. Being a pilot is even worse considering the twin towers/aircraft connection - lets say they are somewhat jumpy about foreign pilots.
Lots of work in the US though , so I wish you luck - I think you'll need it.
