I attended an international school(Concordia International School Shanghai to be exact) for my first two years in high school, but since I have spent two years in America I will apply as a domestic student. How much weight and impact will attending an international school such as CISS have on my chances of being accepted into higher-caliber schools(but not Ivys) such as NYU, BU, and UC Berkeley?
I can't think of anything that would impact you negatively. I don't know much about international schools but if you are going to apply as domestic it might actually help you as an interesting experience you can talk about. As long as you took and continue to take higher level classes like AP you should have good chances to get into selective schools. If your international school didn't have anything equivalent to AP classes you should still be fine as they look at what was offered by your school when seeing if you made use of all the opportunities available to you. The main problems international students face is that they usually have higher standards for admissions for them, they aren't eligible for most aid, and that depending on the country they are required to take a English proficiency test.
