The bigger picture is that many IMGs are just as competent of physicians as are their US counterparts, and in some respects excel often them. Granted, there are also IMGs who are less competent than them.
Even so, to broadbrush a whole class of individuals on the basis of some less competent ones in their class is not only erroneous in logic and communication, but irresponsible and a displaying of what in reality is largely fickle bias apart from knowledge.
The assertion that SGU, Ross, and Saba sell diplomas has at this point absolutely no basis whatsoever in fact. I know of not one official contention in this count of a graduate of one of those schools not making it honestly through the curriculum there amidst much hard work--in some cases, with actually more hard work and perserverance than at a U.S. school.
~10 years ago there were three schools that more or less were diploma mills in the Dominican Republic who were shut down by CONES, the educational authority there. And only a very small figure of people who were already PAs, DPMs and the like were able to make passage of the USMLEs after getting advanced standing from them on the basis of former coursework at PA or DPM school. Which brings me to another point.
How can the assertion be made, more or less, that IMGs are not even worthy to be seen when each one has had to pass the exact same tests that any US medical graduate has had to pass, the USMLEs. Granted, these are only tests, but they are nonetheless whoppers as tests go. So those IMGs who do not make it honestly through a real medical curriculum have a BIG problem awaiting them the USMLEs. And how can one make passage of these without true knowledge of the subject matter?
