First of all, being on probation for a misdemeanor assault charge does not prevent you from applying for a firearms permit, unless it was domestic violence or you have a specific condition of your probation not to apply for firearms permits. You can get your probation terminated early, but the longer you do on probation, the more likely it will be granted. It's typical to make that motion at around the two year mark, although it can be granted earlier if there are compelling circumstances. Perhaps the court will find that you applying to the sheriff's department is a good reason to terminate your probation early. Your employer should write about how great an employee you are and how much you've grown and changed for the better and what a good guy you are. A lawyer would be helpful.
I moved you to criminal defense and out of litigation.
