what exactly do you want to know? PHL....that's Philly, right? are you going to be living there for any amount of time?
some things to know about Philly:
you need a PA LTCF or other recognized permit/license, like a PA non-res or UT/FL/VA etc permit to carry openly or concealed within city limits.
Philly PD WILL stop and detain you, and might possibly confiscate your firearm, and make you fight to get it back.
LTCFs are issued by County Sheriffs in PA, except for Philly, where they are issued by the Chief of Police. if you are going to be living in Philly, be aware that they make it extremely difficult to obtain your LTCF; they use various excuses, which often violate state law, like: unpaid parking tickets, misdemeanor charges that aren't prohibitive offenses, unpaid child support, etc....anything to prevent the citizenry from legally carrying. as yet, no one has challenged them in court.
my advice is, apply for a UT/FL permit, and a PA non-res (Centre County is by far the most cooperative of the issuing authorities), and keep your VA permit. make at least two photocopies of each, keep a copy of each in your wallet, a copy in your car, and leave the originals somewhere safe. Philly PD are also known for keeping licenses illegally, after detaining citizens for open carry. many are under the impression that out-of-state permits aren't valid in PA; they're wrong, but they continue to act on incorrect information, which is propagated by the city government, and the local media.
out-of-state permits are one of the central issues in the case of Gerald Ung, a man who used a firearm in self defense some months ago in the Old City section of Philly. at the time of the shooting, he had a valid VA permit; the Philly DA insisted that he was carrying illegally, even though PA has reciprocity with VA. if the district attorney of Philly is ignorant of PA gun laws (and i'm sure it's more willful stupidity than innocent ignorance), then don't expect Philly PD to be any better.
in short, open carry in Philly is a risky business. if you're committed to doing it, i hope you're ready to lose a gun over it, at least temporarily.
