i just went through a little of this myself, when moving from NJ to Texas.
I think the bottom line is students get a little more of a break as far has
how long they are allowed to wait until these things start expiring. I think, when you move, in most
cases you have like 30-90 day to get your license switch over. Essentially though it will
all come down to proving your residency. For this you will usually need 2 or 3 anchoring documents,
like a utility bill, deed or lease, pay stub, bank statement, etc, etc. For a student, especially on campus,
it might be a bit tricky gathering all the paperwork. I think for the Health Insurance I worry the most,
God forbid you need a hospital and they wont cover you, out of state!! For my daughter, it's really twisted,
because, she goes to school in NC, and since I just moved from NJ to TX, her official residence has appeared
to disappear from underneath her.
