What universities should I aim for? 2.6 GPA from Brazilian School, US resident.

Miami Dade has a good national reputation. It is consistently ranked as one of the top, if not the very top community college. Go talk with the admissions office. Find out how soon you would be considered to be a local resident for tuition and fees purposes. Meet with the Transfer Advisor, and get specific advice about transferring from there to the Florida universities and to universities in other states. Meet with the career office about your longer-range goals. Even if you decide to move and study somewhere else, you will learn a lot from conversing with the team at Miami Dade.

Unless your parents truly are able to commit to paying the full costs of out-of-state tuition and fees for all four years, you want to think very carefully about studying in a different state from where your parents live. In some states it is not possible to establish residency on your own until you meet certain requirements (24 years old, married, US military veteran, etc.). In some states it is possible. In some states the rules are different for community colleges than for 4-year public colleges and universities. So check all of that out too.

@aquapt has made a good suggestion about identifying places that would offer provisional admission to you provided that you start out in their intensive English program. Lots of places do that. You also could consider enrolling at an ELS Language Center or other similar program that has provisional admission agreements with multiple colleges and universities. The ELS Language Center in the Miami area is located on the campus of Barry University. You could visit them and hear their sales pitch.
