Where Should I Apply?

I’m currently a high school junior from a Detroit suburb in Michigan. I’m looking at colleges and trying to find ones I’d like to go to, but as I’ve only recently decided what (I think) I want to major in, it’s been sort of a hard task.
I currently hold a 3.7 (UW) GPA, take mostly AP and Honors courses, am currently president of two clubs (Gay Straight Alliance and Model UN) and plan on forming a Diversity club during my senior year. I take the SAT in about a week, but my projected score is in the 1300’s.
I plan on being an international relations / politics major, so that particular program in a school is very important to me. A study abroad program, especially a good one, is also important.
Financially, I need a school that provides good merit aid. I come from a high income household, but my parents have informed me that they will not assist in my college payment, and so all of my tuition will be paid through loans and merit aid scholarships.
I am also looking at going to a university in Europe, rather than going to an American university and studying abroad through the university. If anyone has recommendations for universities in Europe as well, I’d be more than grateful.
I want to go to a small or medium college, although I would not be against going to a large school. Having urban or suburban surroundings is also very important to me. Diversity on campus is also important.
Currently, I am looking at U of M Ann Arbor, Kalamazoo, Tulane, and NYU, to give you somewhat of an idea.
Thank you so much! I really appreciate it.
