The only way any US air carrier would hire you would be as US citizen, or holding a green card. Your only solution is a green card, whichever way you could get it. No other solution. And if eventually you qualify for one, as an example, by marriage, it will take you a year or so to get it. Not too many airlines hire in the US nowadays with the economy as it goes... will be years before it happens again.
