How can I expunge a felony drug charge in virginia?

Hi There,   In Virginia, an expungement can only be obtained if: you are found not guilty by the court (acquittal or dismissal); the charges are withdrawn (nolle prosequi) by the Court on a motion by the Commonwealth; where an individual’s name is used in error; or the individual obtained an absolute pardon from a Virginia Governor.
