Chances at Notre Dame, Northwestern, etc....?

I wanted to know what my chances were for schools like Notre Dame, Northwestern and even some of the ivy leagues. I am a minority (immigrant parents) and a 1320 SAT (hoping to raise it up). My gpa is about the same but of course each school looks at it differently. I have done a lot of community service and two different sports for two years with other clubs and a few other extracurriculars. Also I believe I will write a good essay.
