Pakehaboy,
Are you referring to the US or elsewhere ?

c100driver,
I doubt you'll see much if any animosity. The expats who fly here are relatively few percentage-wise and do so legally via green card, dual citizenship, visa, etc. The process is a bit involved under the best circumstances. If you can jump the hurdles, welcome aboard.
We have a HUGE freakin' aviation industry here...room for lots of people.
