A Pardon is a process that can get your criminal conviction erased from your record. I.e., a severe misdemeanor or felony from your record. This is based on the Pennsylvania Board of Pardons recommendation. The Governor is the one who grants a pardon. Pardons can remove obstacles that are keeping you from improving your life.
An Expungement refers to the method of sealing arrest and conviction records. Pennsylvania laws allow people to expunge arrests and convictions from their records. State laws provide that when an arrest or conviction has been expunged, it does not need to be disclosed, including any potential employers or landlords.
