I made the mistake of using 4 psych LORs for ERAS. Will there be any issue with that? I do have an IM letter, but I didn't utilize it and it doesn't appear there is a way to undo it.
I'd look at the websites for the specific programs you applied to. Some programs say things like "at least 3 letters, 2 of which must be from psychiatrists;" or "at least one letter must be from a specialty other than psychiatry." I think even some just say "at least 3 letters" and don't specify further.

I would call ERAS and see if you are able to switch assignments. I'm not sure why you would ask 4 people in psychiatry to write you a letter AND get others to do it as well.
Why are you worried? I am an IMG, applied with 4 psych LORs, had 15+ IVs. I am not sure if its different for US MDs, but I cannot see the problem with using only psych LORs.
