First, did you change your permanent residence to VA? What is your long-term intent? Did you change your domicile?
I recently found that the PA tax web site has a very thorough discussion of domicile.

It's possible to change primary residences for a long period of time without changing your domicile. Determining your domicile is the first step to determine how to file.
