From what I have read and heard, obtaining a good residency depends a whole lot more on your USMLE scores than anything else. Even I you go to a US school and screw up the USMLE's you will not get into a competitive residency.

As you have probably already read, St. Georges, AUC & Ross are considered the "Top Three" schools. Myself, I am probably headed towards SABA which is also a good choice. According to SABA, t99% of their grads got residencies in 2003. The top three probably have similar or better stats.

I don't think the problem is obtaining a residency, as this can easily be achieved by decent USMLE scores. I think the real issue you must address is where you want to get licenced. Licensure is much more difficult and not all schools are equal in this respect nor does it depend on your USMLE scores. The "Top Three" are accepted in all 50 states, but some are more tricky than others: Texas, Kansas...
