The airlines have started to hire again in the USA. Since you are a green card holder you will have to undergo 10 year background check by Department of Homeland security before you can fly a plane with a MTOw 12,500 or greater.
Most companies in the USA look for either part 135 minimums for Single pilot operations or 1000 hours total time and 100 in multi. It definitely helps if you have already passed the FAA ATPL exam and that you hold a Bachelor degree.
