I think this is going to be tough. First it is harder for an international to get aid, second it is hard for a transfer student to get aid. I don’t think re-taking the SATs will help a whole lot as standardized test scores for students with over a year of college and these tests are meant for HS students so how you do after some college may not be especially relevant… This isn’t what you want to hear but I’d look hard at the options in your home country.
