well, your chances of getting a work visa are slim. The rules are that only professionals who are not in abundance and are absolutely crucial for the company may get work visas for up to 3 years (no more after that). That being said, the only place were pilots are important and are not in abundance is in alaska.
The reason the US doesn't let you work (in fact, this applies for every other country too) in their country is because they wouldn't want you, the foreigner, to take a way a job position for an (lazy) american. seems reasonable enough, i guess.
What other options do you have? Green card. Well, i've lived here half my life, and they wont even give me a green card - well, i've spent my entire teen years here - but they say "Rules are rules". So how can YOU obtain a green card? easiest way is to marry a US girl

. Next "feasible" option would be to invest 1 million into the US economy and employ at least 10 americans for over 2 years. There are a few other options, but a lot tougher then the previously listed

. As you can see, i've looked into it. And let me tell you, your best bet is to win one, or marry a US girl (or man)
... looks like i said a lot more than i wanted too.. oh well
