This is what I've found through my research:

Pennsylvania law provides that, subject to certain limited exceptions, no person shall possess a firearm if he or she has been convicted of:

Possessing, using, making, repairing, selling, or otherwise dealing in any “offensive weapon,” including machine guns, sawed-off shotguns, firearms with a silencer, and stun guns1;

An offense relating to organized crime;

Possessing a weapon on school property;

Murder;

Voluntary or involuntary manslaughter involving reckless use of a firearm;

Aggravated assault;

Assault by a prisoner;

Stalking;

Kidnapping or unlawful restraint;

Rape, involuntary intercourse, or aggravated indecent assault;

Luring a child into a motor vehicle;

Arson;

Causing or risking catastrophe;

Burglary;

Criminal trespass (at the level of second degree felony or higher);

Robbery or robbery of a motor vehicle;

Felony theft or felony extortion accompanied by threats of violence (if it is the second conviction for said felony);

Felony receiving stolen property;

Impersonating a law enforcement officer;

Intimidation of, or retaliation against, a witness or a victim;

Escape from “official detention”;2

Possession of weapons or implements for escape from a detention facility, correctional institution or mental hospital;

Riot;

Paramilitary training;

Possession of a firearm by a minor or corruption of minors;

An offense involving “facsimile weapons of mass destruction”; or

Unlawful sale or lease of weapons or explosives.3

Pennsylvania law also prohibits the following individuals from possessing a firearm:

A fugitive from justice;

A person who has been convicted of an offense under The Controlled Substance, Drug, Device and Cosmetic Act;4

A person who has been adjudicated as incompetent or involuntarily committed to a mental institution;

An illegal alien;

A person adjudicated delinquent under federal or state law as a result of conduct which, if committed by an adult, would constitute specified offenses under Pennsylvania law for a period of 15 years or until the person is age 30;5

A person who is the subject of an active protection from abuse order that provides for the relinquishment of firearms; or

A person who is prohibited by federal law from possessing or acquiring a firearm because of a conviction for a misdemeanor crime of domestic violence.6

A person who has been convicted of driving under the influence on three or more separate occasions within a five-year period is prohibited from purchasing but not possessing a firearm.

None of these apply to me. I was convicted of DUI twice. The first time I got ARD and it was expunged, the second time is the one mentioned in my post.

Outside of that I have no criminal record. According to everything I can find, I should have been permitted a license to carry. I also should still be able to purchase firearms, federally and within PA. I'm really just baffled. I have looked into expungement, and it's impossible outside of a governor's pardon, which is highly unlikely and uncommon. I guess it's time to speak with a lawyer. It looks like I do have an avenue of petitioning the Court of common pleas in my county.
