For the last time, you will remain a resident of VA. Like Erin’s Dad said, the website you’re referring to is regarding taxes and what status you have to be to file Virginia taxes. If you look under the definition of resident, it says:
“A person who lives in Virginia, or maintains a place of abode here, for more than 183 days during the year, or who is a legal (domiciliary) resident of the Commonwealth is considered a Virginia resident for income tax purposes.”
You will be a domiciliary resident, but that’s still a legal resident of Virginia. It looks like there’s not really a difference between actual and domiciliary as far as benefits go. Until you become a resident of another state (which you actively have to try to become, you won’t magically become one by living in a dorm at x state), you will remain a resident in the state of VA. Again, look at my situation–I attend college in Missouri but am still a resident of VA (because I live here on breaks, have a VA driver’s license, and vote in VA elections).
