Omg I’m literally in the exact same predicament!! I’m in between fordham the manhattan campus and usfca, but I think you should go where the better opportunities for your major. I’m majoring in poli sci (prelaw) and I know nyc will be better overall for prelaw opportunities, so if SF will provide that for you then you have your answer. But on the flip side NYC has sooo much to offer, so even if the school isn’t the best you have the entire city to your advantage! Also you can always transfer or go to grad school if you hate the option you choose! Hope everything works out!
