please, don't believe some arrogant students telling there are plenty of jobs in the USA, and some airlines will sponsor you for a work permit.
if it was the case, most EU pilots would go to the USA and there would be a big shortage of EU pilots in Europe.
usually this kind of stories come from unexperimented students(0-200h) who have no commercial license, and who have been brainwashed by their flight school.
Believe the "looks too good to be true".
