You probably could, though forget this year. Shoot for applying this fall/winter for admission in fall of 2017. But we need to know more: Targeted part of the country? Budget? (50% tells us nothing: 50% of what?) Also, estimated SATs are sort of silly. Hard to help someone who has theoretical stats only. As you probably know, there is little financial aid for international students, so you will have to dig deep and apply to a lot of schools to increase your chances. You should also look at schools where your stats place you in the top 25% of incoming students, and be open to all kinds of universities, not just the well known “good colleges” where everyone applies.
