You won’t get instate tuition simply by moving to Maryland…sorry…you won’t. Your parents would need to relocate to Maryland…and they would need to establish your family residency there. And one semester wouldn’t be long enough anyway. Your parents and family would need to be there at least 12 months before classes start.
And if there is an inkling that your residency is JUST for instate tuition purposes, it could be declined.
Your plan is a faulty one if it is counting on instate tuition for Maryland.
Are your parents on board with relocating?
And adding…you are instate for VA which has a bunch of terrific public universities.
