All of the moving/getting new licence registration isn't applicable for students. As a student you can remain a resident of your home state. Or, atleast that is the case in Oregon, New York and California the three states I have dealt with this for. However, you do legally need to tell your insurance company that your primary address has changed. If you don't inform them they can deny you coverage for lieing to them. The insurance companies just want to know where the car is housed most of the time, not what state the licence or registration is for. It can get a little tricky but my insurance company, Geico, issued a registration with my CA address even though it is NY insurance. I don't think the different address thing is a huge deal, but something to be aware of.
or atleast that is my read of the laws from reading them and consulting with my dad, a real estate attorney.
