Anyway, coming at this as an inverse gunner, I hope to elicit discussion that focuses on actual programs. What are the easiest programs to get into (having just scraped by at a US med school) that still have good training?
I don't think there are any stats or rankings on the lower end of competitiveness, and "good training" is somewhat subjective. Your best indicator is probably to look at the program's website and see if they list the med schools for their recent residents to help you gauge competitiveness.
*In general*, most residency programs' preferences seems to be:
American MD > American DO > Caribbean grad > Foreign grad.
I also agree with billypilgrim that geography is a huge factor too, with midwest/southern programs typically being less sought after. Even the crappiest program in California will still be pretty competitive just because so many people desperately want to live in Cali.
If you're applying to a program that is mostly FMGs, you do run the risk that the program may in fact truly prefer IMGs/FMGs for some reason and actually doesn't *want* AMGs (for example, some programs prefer FMGs because many of them were attendings in their home countries and the program appreciates that they already have a lot of experience/knowledge from that; sometimes if the PD is an FMG him/herself they may prefer their fellow FMGs, etc.).
A program may also reject you if they think you're "out of their league" or not the kind of person who sincerely wants to be at their program.
But you have to start somewhere right?
So, with all that being said, here are a few programs that I'd probably try investigating if I were you. By that I mean, based on what I've heard, I think these are programs where you'd have a shot at being seriously considered. You'll have to decide for yourself if you think the training there would be good for you.
