Hello,
I understand that traditionally that is the way it works, but it seems according to VA law (linked in my original post), I do in fact have to file as a 'resident' of Virginia:
"Students are subject to the same rules for residency and filing requirements as all other filers. For example, if you lived in Virginia for more than 183 days during the taxable year, you are classified as an actual resident, and must file Form 760 even if you maintained your legal residency in another state"
