I once asked the late Dr. Claude H. Organ who was the president of the American College of Surgeons(
http://www.nlm.nih.gov/exhibition/aframsurgeons/organ.html) in a conference about the contributions of IMGs in American surgery. He started by naming the heads of several departments of Surgery who are IMGs and mentioned recognized their contributions. He then replied " I will tell you what I tell my African American residents, it is not an excuse!. You have to show me some performance." On his way out, he stopped with his entourage which included the chief of surgery at he institution he was lecturing , the head of the cancer institute and several high-profile surgeons to talk to me, at that time a lowly medical student. He asked me where I went to medical school..and when I told him..he smiled and said " it is NOT an excuse". ( words not quoted verbatim as this was many years ago)
I think this was a great peace of advice and it made such an impression on me.
Having come from a country where there is actual discrimination when it comes to promotion in the medical field. I will say that I am very grateful to the United States for giving me the opportunity to reach my goal if I pay my dues. That opportunity does not exist in other parts of the world where you can not change things EVEN if you pay your dues because you can not change your skin color or your religion. Yes, here in the US , I had to work harder or longer than my AMG counterparts to reach the same goalpost but as one of more reasonable posters said " You have to pay your dues" or as Dr. Organ said " it is not an excuse".
That being said, and as the same reasonable poster initially pointed out , this arrangement is "mutually beneficial". I would add that it is "equally" mutually beneficial. It is true that the US has a lenient visa policy when it comes to physicians as compared to countries in he EU but This is "need based" . In fact it is anticipated that in the coming years that it will be much harder for IMGs to come to the US ( see JAMA. 2012;308(21):2193-2194. doi:10.1001/jama.2012.14681 ) .The US is the great place that it is now because it has always attracted a pool of talented people from around the world who generate innovation, progress and help the economy. The US needs this pool of talent and innovation in all fields ( including medicine and science ) as much as these smart hard-working people need jobs and visas. There are no favors in this arrangement.
