I am a graduate student living full time out-of-state (in VA). However, my license & registration is in my home state (WV). What do I put for my state of residence?

I lived full time in Virginia in 2016 and made all income in VA. However, I am from WV and my license and car registration are in WV (my parents' address). I consider Virginia my home but have not yet transferred items like my car registration over yet. What do I claim as my state of residence on my taxes?
