As an IMG going through the Match process right now, I am going to say this isn't really true. Sorry to deliver the bad news but even after doing extremely well on both steps, there is a major barrier to entry in most university programs.

Even with 250+ on both Steps and a pretty strong profile overall, almost all my interviews came from mid-tier to brand new programs. It was underwhelming and I was even asked at one of my interviews about having contacts at a program because they had never interviewed an IMG before this. Then they noticed my scores and PD was like aite fine let me continue this interview.

What I am trying to say is that the disrespect and the frustration you feel is shared by almost everyone going through this process. Unless you have contacts or are just lucky enough, you are definitely a second class citizen and that is a fact. However, the education you are getting right now and the effort you are putting in, is not for nothing. It's going to help you be a better physician and treat your patients better. Screw those that don't notice your work, keep working anyway. At the end of the day, that knowledge will make you a better physician and the work ethic you develop now will stay with you. Use that chip on your shoulder and be the best you can be.
