The best way to examine this question is precisely to stratify by immigration category.
I am sure that programs dont "discriminate" on the basis of visa status - but it is also a surrogate for medical schools abroad, perhaps community based programs , lack of research or access to top faculty in the field who can write letters or call up programs.
anyway. should be an interesting experiment... if one chooses to do so.
I started the process of differentiating the ivs based on visa category in the GI forum and feel obligated to give the basis of doing it as three lists.
1. It is definitely not a level playing field. Many programs do not sponsor visas, at least in the GI world. Although some of them have NIH sponsored spots that cannot be given to visa requiring candidates, majority of programs are ACGME sponsored and have capability of giving visas. I was told by many seniors that the program has to explain to the administration about why they are ranking visa requiring IMGs higher than AMGs and get approval of the bosses. If this is new to you, then you probably aren't aware of the match statistics from ERAS 2013. Please see page 66 of the link below.

As you can very well see, non US IMGs who matched in that cycle required higher mean step 1, 2 scores, more abstracts, more work experience than AMGs who matched in the same cycle. Page 69 shows you how many AMGs applied and matched vs how many visa requiring IMGs applied and matched. This is actual reality in the real world. IMGs in this forum are not fighting that this is wrong but just to write it off that IMGs are in equal level playing field as AMGs is a wrong assumption
2. Why should the list be differentiated into 3 categories? One is for peer to peer comparison. AMG wont know which programs he has a stronger chance and same applies to IMG when looking at an unified list. Some programs do prefer AMGs over IMGs and having a list that shows that will help the applicants in the future definitely. When someone is short on money, he can at least make sure he applies to all the programs that called for IVs in his category. Doing the list in 3 categories is not going to hurt anyone but actually be more beneficial for the respective groups. An IMG can look up the list and know where he stands. Unlike AMGs who can get a job instantly when they dont get interviews, for IMGs, even securing jobs are difficult. Have you guys heard about waiver jobs? Do you know how tough it is to get waiver jobs in a desired location? The application has to be filed on October 1 for starting a job next july 1 and once application is filed, the person cant participate in fellowship match. This list will help such applicants who are in a vulnerable group. Unless you had IMGs in your residency program who are on a visa, chances are that you never heard of these.
Again this reply is not to hurt anyone but inform others. Still if you do not want to have the list categorized, its upto you guys in this forum. But do understand that it will benefit someone someday and it doesnt hurt to have a list that has 3 categories.
Good luck!!
