You don't necessarily have to be an American citizen to work in the US. BUT, you do have to be here legally with the "right" to work, the proper VISA, etc.
Your misrepresentation of speaks for itself. Sure there are lots non-US citizens working for airlines, but they'd better damn site have the right to work here. Maybe the gentleman from Norway who claims to gleefully violated US law a while ago by flying for a commuter illegally would like to tell his current employer that he has no respect for obeying US laws. Maybe he thinks respecting FARs is beneath him also.
Thanks for the info, Ichnusa. As far as people working in the US without the "right" to work here, they'd better be looking over their shoulder. I'm going to fire off a letter to my senators and representatives today and enclose a copy of this thread. We Americans are in a very foul mood right now, especially with people who cynically abuse our hospitality and good will. To those who respect our laws and do it right, welcome. Glad to have ya flying our "shiny jets". To the rest like you Ichnusa, ******-off.
