You know, it's not necessarily making a living over there. I was thinking like, what if I want to go volunteer to help poor patients in HK, Macau, and China. The problem is, all three places have different regulations (and although you fulfill China's regulations, you still do not qualify to practice in hk or macau) even though they all belong to one country. This is what sucks, because especially in China and Macau, their healthcare system is horrible and could use some good quality US graduate physicians to volunteer once in awhile, yeh the regulations are so complicated that they discourage such practice.
