As per the pay sheet I received,your base pay is $13500 then your bring home is $9017.At least its good to know the US will not tax me again but I still think you will have to pay your medicare tax and your social security tax, if not you would have nothing when you retire.
I'm not against taxes but as a foreign pilot that is quite a bit to give to the state of India.I don't imagine for the 4000 plus dollars you are giving you're going to get any benefits from them. At the end you may get a note saying "its been a pleasure doing business with you and you come back anytime"
