I think it does matter in some ways. I found it very interesting this year in that the people who had interviews at school like Cornel, also had them at Columbia, NYU, and Mount Sinai. I think schools tend to favor students they think would go to that school, so they tend to interview a lesser candidate from nearbye than a great candidate from far away.
I know of one person with a 27 MCAT, and goes to school in Boston, and she got an interview from Boston Univeresity. But I don't know anybody else who got that interview.
And it seemed like at the school I'm prolly going to (USC) most of the people I know of who got interviews there are from the west coast. So I would actually consider changing your status to New York, if you can. I think it would help you get into NYU, Columbia, Cornel, Einstien, and Mount Sinai. It would hurt you at IU, though.
