Thank you for your follow up.
Unfortunately, while Governor can grant an official pardon for the crime, once Petition for Pardon is filed with Governor's office, any letter from Governor would simply be a personal reference / recommendation, which can help the situation, but it would not have any legal effect when it comes to the misdemeanor conviction.
So, generally, unfortunately, there would not be any way to speed up the expungement process, and the only option that person in similar situation might have, is to offer personal references / letters of recommendation from established members of the community and/or government officials and also to offer detailed explanation to any potential employer as to when and how this conviction took place.
