The only entity that can lift your probation is the Court that imposed it. If this is as important to you as you indicate, do not do this half-way. Contact a local defense lawyer who will know the procedure and have the forms to request that the matter be reheard by the Court by way of a Motion for Reconsideration of the sentence. I have made such Motions here in NJ for similarly situated clients and been successful at getting the probation lifted. Typically, the Court wanrts to see the enlistment papers, or talk to your recruiter. Good luck.

A motion must be brought before your sentencing judge. You should make certain that all other conditions ordered at sentencing have been satisfied prior to the hearing. (i.e. Chemical health assessment and recommendations, MADD panel, etc...) You should contact your attorney regarding this motion. If you do not have an attorney, you should immediately begin interviewing firms. Our firm has handled this type of motion many times in the past. Feel free to contact us for a free consultation.
