I have a friend who flies in the Alaskan bush. It is hard to get work there even for Americans. You have to have quite a bit of time actually flying in Alaska. My friend got hired because she did all her training from 0 hrs in Alaska and started out as the telephone receptionist for a flying outfit.
There is also African bush flying (I currently know a Brit in Botswana), and I've met a couple guys flying in Latin America but that was more missionary work.
