chrtrplt,
We've just hired a bunch of American pilots.
Personally, I think it would be harder being here as an American than other nationalities, but that would be up to you. Most people I talk to hate George W, but not all Americans. If you keep your Republican membership card safely tucked away, you should be fine.
Bottom line is if you are open minded and a decent bloke, you should not have any problems.
Not sure if that answers your questions or not...
