Internal Medicine is an exception.

From what I have heard, internal medicine is definitely an exception to CMG's. There seems no limitation of “只招医学院毕业三年以内的” to CMG's that apply to resident programs in that specialty. I even know that a CMG resident in internal medicine graduated from medical college at least 12 years ago.

This of course is in accord with the background that the US now is in great need of internal medicine physicians.
