Check out the match rates for residency and you'll get an idea on the stigma. the order of success of matching goes as follows:
US grads>Osteopaths>canadians>UScitizens who are IMG's>foreign IMG's.
I do know that the US IMG's have like a 54% match rate, and the foreign IMG's have like a 45% match rate. US grads are like 97%, and osteo's are like 70%
