Actually, the differences are usually pretty profound. At some programs, they'll get 1000 apps for 20 slots, and 900 of those apps will be FMGs. Out of those 900, you'll get some crazy high stats from a few. I was reading about a guy with a 260 Step 1/272 Step 2 that only got 3 interviews out of over 150 applications as an IMG, for instance. That gives you an idea of how hard it is for even a very, very highly scoring candidate to get an interview- the ones we do end up interviewing and keeping are often far and away above the US grads they're competing with at a given institution, if they win out. We don't need government interference in our match process, there would be massive unintended consequences that you, as a premed that likely has minimal teaching hospital experience, cannot even come close to fathoming. The process works, trust me. PDs are smarter than me, or you, or our ******ed government when it comes to picking the best doctors for their training program.
