High schools in the USA for international Students

<p>Hey, i am an international, straight A, student. I am about to go to grade 11 this Fall. I wanted to know whether it is possible or not that i can attend grade 11 and 12 in High schools in the USA. What schools can give me an f1 visa ( or any other way of going, living and studying there till i finish high school )? Is there any kind of financial aid? i can't afford high priced tuition fees. So is there any high school suitable for me? I don't care in which state as long as it is in the USA. Any help would be highly appreciated, thanks a lot.

That is a good way to experience life in a different country.</p>
