State & Regional College Tuition Discounts - National Association of Student Financial Aid Administrators

Many states have programs that allow residents to attend university in another state, without having to pay out-of-state tuition. Check with your state, or with universities that you're interested in, about available tuition exchange or reciprocity programs, and ask about how to sign up. The FAFSA is not required for these programs, generally.

I'm sure this has been posted somewhere before and honestly not sure how helpful this will. My state is the ONLY state in the South, of course, that has opted out (eye roll) so hopefully this will help someone else.
