Wow. You beat me to it.
I was discussing this on a thread before Obamacare became the law of the land. We were talking about all the restrictions on doctors and that we would have a shortage of doctors because nobody would aspire to be one any more.
And then someone mentioned that it would be like the UK. All the doctors would eventually be foreign born.
And here we are.
Most people are not aware that the Immigration Act of 1965 (Ted Kennedy's handiwork) allows UNLIMITED annual Green Cards for foreign born MDs.
