<p>You need to get a green card in order to be able to apply as a US student and be eligible for FA and merit scholarships at most US colleges. Ask you parents what their plans are for becoming US citizens.
That said, there are a few colleges that give out a few International student scholarships, such as USC. If you do extraordinarily well in HS, [and you seem to be off to a good start already], then you might have a chance to land one of those rare international merit scholarships. But, your odds of acceptances at good colleges as well as landing merit or need based $$ are going to be MUCH better if your parents can get green cards in the next 2-3 years.</p>
