I'm an IMG... I had no prob at all- and i know lots of IMGs who are working in the field- I wouldn't worry about it. Just work hard make a goal and aim for it.
When i was applying I noticed 3 levels for residency prgms: 1st level was way up there, and they were looking for scores in the 90's and research experience and other crap- and yes, they prefered AMGs- from what I could see- for example u'd see that 99% of current and past residents are AMGs, and the trend not likely to change. There were exceptions of course. Apply early if you want one of these places.
The next level- and this is the majority: have a cutoff point of 85, and this is both IMG/AMG friendly- and u'd prob find a mixture of both grads in these programs, and these are good programs, and worth the effort. If your not an absolute star I'd focus on these.
The last level- have no cutoff at all, as long as u passed- these are in underserved areas/ programs on probation/ not that great programs/ in the middle of nowhere, and these take both IMG and AMG, just anyone who'll go.
So, there's something for everyone.
How to know: visit the websites of programs, see the residents profiles, attendings profiles too, talk to someone there if you can, ask the secretary what their cutoff scores are and if you are the type of applicant they would look at, and... ask for an interview!
Good luck.
