Yeah, if you talk to people who are working in custodial work, you'll find their lives in other countries were very interesting.
There is a way to evaluate/test doctors who come to the US, and a lot of the ones who pass are working as residents in teaching hospitals. But it's very difficult for them to remain in the US after they finish. Many are in specialities that are already well-served, or they don't want to move out to rural areas where they're needed.
Not a lot of Eastern European doctors end up credentialed. Some foreign medical schools are as good or better than those in the US, but others don't seem to teach what people need to know. Iranian doctors used to be great (I met a doc who came to the US after he stole an ambulance in Khomeini's Iran and got out of the country by driving across the border with the lights flashing), but I don't know if that's still the case.
@AlphaCentauri I am not surprised. This was many years ago and I can think of one doctor from Romania, specifically who had a very difficult time but who did eventually go back to obtain the degrees he needed. I doubt he is still living, now. He was well into his fifties at the time.
