Help! I'm international. Do I have a chance to get to Brown?

<p>Hello!
I am currently an exchange student, junior, at selective private high school. Next year I am coming back as an international student and I will try to apply to colleges. My GPA is 4.0, I’m taking just one honors class this year because my school has a huuuuge list of classes I need to take in order to graduate. Next year I am taking 2 AP classes and one honors. All APs and honors are in science. I have awesome letters of recommendation, also my essay is outstanding. Unfortunately, I wanted to volunteer in various hospitals but all of them told me that I can’t volunteer there because I am not a citizen. My EC is a creative writing class. I used to do ski racing. Both my parents didn’t get their high school diploma. I come from the Czech republic. I am taking my SATs in May, aiming for high score. Also I’ll be taking the Subject tests in June. Do you think I have at least a little chance to get to Brown? What would you work on? Thanks!</p>
