You posted a similar question a couple of months ago. As a US citizen, you qualify for the federal student loan. Your parents aren’t US citizens, so I’m not sure if you qualify for a Pell grant. They can only pay $5k/year, so you need to find a school that offers tuition grants for your ~1200 SAT/3.6 GPA.
The best aid comes from the colleges. Most outside scholarships are only for a few hundred dollars and many schools subtract those awards from the grants they offer, so unless you find a large (renewable) scholarship and a school that stacks aid you’re better off focusing on schools that offer merit for your stats. Have you applied to any financial safeties (either in the US or Brazil)?
