Hi! MS3 at SIU here!
"If you are not an immigrant..." -> I don't see how this would matter if you're a resident of IL. Anyway, not true, we have an immigrant in our class.
"If you are a URM..." -> Blatantly not true, plenty of URM here.
"If you are NOT living in the south of IL..." -> Kind of true, but also plenty from central Illinois. Plus, we also have some students from the Chicago suburbs, and a few from out-of-state.
I don't really know what you're trying to imply by your next statements, nor do I know if your claim about lawyers running the admissions office is valid... I'm pretty sure it's medical faculty
