Does a presidential pardon expunge or erase the conviction for which the pardon was granted?
No. Expungement is a judicial remedy that is rarely granted by the court and cannot be granted within the Department of Justice or by the President. Please also be aware that if you were to be granted a presidential pardon, the pardoned offense would not be removed from your criminal record. Instead, both the federal conviction as well as the pardon would both appear on your record. However, a pardon will facilitate removal of legal disabilities imposed because of the conviction, and should lessen to some extent the stigma arising from the conviction. In addition, a pardon may be helpful in obtaining licenses, bonding, or employment. If you are seeking expungement of a federal offense, please contact the court of conviction. If you are seeking expungement of a state conviction, which the Office of the Pardon Attorney also does not have authority to handle, states have different procedures for "expunging" a conviction or "clearing" the record of a criminal conviction. To pursue relief of a state conviction, you should contact the Governor or state Attorney General in the state in which you were convicted for assistance.

Take my advice fishpap. Quit being morons and stop spreading your false BS on this site.
