Just to comment on the IMG portion of UPMC:
There are 5-6 each year, and they put them in a separate track and have them do a very similar curriculum of that of Shadyside program (which is a community program in one of the UPMC teaching hospitals).
Those IMGs are not part of the categorical program, in fact, residents of the categorical program seem not to like them. Even interview process for IMGs is different: they don't get invited for a pre-interview dinner with the residents, unlike AMGs, and they dont get any interaction with (categorical) residents during the day (other than the chief resident that does the hospital tour).
UPMC presby. is an amazing hospital, and the program is very big on teaching, in fact some people described it as the perfect program (Pitt is a great city, no comparison to cleveland or rochester for example).
However, if you are an IMG, think twice before going there: It was noticed that residents and most staff really hate them. I couldnt understand the reason behind this comment, and I have got it from many trusted people.
When you want to recruit IMGs who are really the creme de la creme (or at least supposed to be), the least you want to do is to integrate them with your regular program, and not ascribe some tag to them. Many of the people that I know (really smart people, many with nature publications and so forth) opted to go to a lesser known university just because they wanted to be treated equally.
In a nutshell, if you are an AMG, this program IS the place to be! if you are an IMG, think twice before choosing it.
