Only M3s and M2s can be expunged, assuming you were found guilty. You will have to file for a governor’s pardon to get it off your record.
You cannot have M1s expunged if you were convicted. You can apply for a pardon, but you are unlikely to receive a pardon for offenses which are that recent barring unusual circumstances.
I agree with both answers above. I comment because Mr. Klein's statement is correct to a degree. A person's record will not be expunged until a person is either 1) Age 70 and crime free for 10 years, or 2) dead for 3 years. There is a new procedure in Pennsylvania that permits an individual to seek to have certain M3's and M2's expunged from prospective employers. However, your record will still remain should you be charged with any future offenses. However, an M1 cannot be expunged even under the new statute.
The proper procedure is to seek a pardon. A pardon usually takes 3 years and can be costly. However, it is not something that you will easily be able to do on your own. Some factors in granting a pardon will be the seriousness of the offense, the recency of the offense, and other pertinent factors.
I notice that you did not indicate the offense that you would be seeking a pardon for. It is highly unlikely a pardon would be granted if the offense is one of a sexual nature, an abuse of animals, a crime involving children, among certain other offenses.
I would recommend you discuss your prospects of a pardon more closely with an attorney.
