So my husband is a college student and we are WA state residents. Now I am thinking of pursuing higher education in Idaho. It would be vastly cheaper if, after a year of living in Idaho, I could apply as an Idaho resident, but obviously, as my husband is going to continue to go to school in WA, it would help for him to keep his Washington state residency. Let me try to clarify what I'm trying to figure out: Scenario 1: We move to Idaho, I go to school there and husband drives across the border everyday to go to school in Washington state. We would not count as Idaho residents during this first year, so would my husband still count as a WA resident? Or would we be residents of nowhere and both have to pay out of state tuition? Scenario 2: Same as above, except my husband uses the address of a relative that lives in Washington state as his address with the college while actually residing in Idaho so there is no reason for anyone to suspect that he's not physically residing in the state. Would this be committing a serious legal or ethical violation? He would still keep his WA state voters reg, driver's license, etc, but I would have to switch mine over to being in Idaho to prove that I'm really a resident and I'd have to switch our car registration over there as well. So in addition to the questions about my husband's resident status, if anyone has any general experience in establishing residency in a state that you moved there to go to college for and how easy or difficult it is, that would be interesting to hear.
