Chance me at T20 for 1510 SAT & Low-income

You have good stats and good extracurriculars, but they’re not so great that you’re a shoe-in at any of these schools. Since most US colleges are not need-blind for foreign applicants, the fact that you need substantial financial aid further reduces your admissions chances. I would add a few match and safety schools to your list, and make sure that you can definitely afford at least one school you’re applying to. Good luck!
