It does vary by every college. Some colleges offer financial aid from the Financial Aid office others offer the aid through the specific department. I would first talk with a Financial Aid Counselor from the school(s) that you might interest you. They would be able to give you a more definite answer as to what you will qualify for and certain scholarships they might have.
Usually, the formula for applying for aid goes as follows: FAFSA (federal Aid); School Aid (check with a counselor), Community aid (scholarships/loans in the area), private loans (must exhaust all options first). I would always apply for aid with FAFSA (which needs to be done every year) and then you can go from there.
