FAA... if you want it to fly commercially you'll have a 6 month to 18 month wait to start flying for airlines unless you were born in the USA. You'll need 1500TT 100 night 75 intrument with 50 of that in actual IFR conditions. Then its a theory exam. (pretty easy) and a check ride...similar to an IFR rating or renewal. Even a green card won't get you an airline job without an extended wait. Plus you've got close to 10,000 unemployed United US Air and American pilots to compete with. It just ain't good.
