So, military service is taking me out of PA, sadly. I'll most likely be making my official residency either back home in Tennessee or in Virginia, where my next duty station is. Will my LTCF still be valid until it expires, or is it rendered invalid once I declare residency in another state?

EDIT: DOH! I just realized someone just below was asking the SAME FRICKEN QUESTION AS ME. Please forgive my lack of visual acuity...
