A few jobs ago when I was working for a regional, we did some quick hiring and were getting down to the lower end of the TT pool hiring CFI's etc. I heard in the crew room we had hired a "bunch of foreigners" to fill a class. I flew with the "foreigners" and found out there were actually two people who were both born overseas... and had been citizens for 5+ years before they started flying. They did have strong accents but their english was better than a lot of the the "Amuricans" I know. I doubt the situation would be any different. NOBODY is getting the right to train from the TSA unless they are legal to be here.
