It is true that there are alot of foreign medical graduates in the USA. Probably up to 50% of doctors in many Cardiology Fellowships (as one example, since I am a cardiologist) graduated from foreign medical schools. Many graduated in India, Pakistan, and other third world countries and came to the USA for a much higher living standard.
On the other hand, very few Americans who grew up here will go that route, since many foreign medical schools would not be acknowledged in the same way as an American medical school.
