Federal student aid (FAFSA) is the same no matter where you go to school. It is not affected by whether you choose to attend an in-state or out of state college. However, a typical financial aid package includes aid from sources other than FAFSA, such as state grants and low interest loans, or scholarships from the schools own resources. In most cases, state aid can only be used if you attend a state school in the state where you are a resident. Institutional aid may, or may not, be affected. In general, if you're planning to go to a state school, you'll do better if you remain in state. If you're planning to go to a private school, it won't matter as much.
