Moving on probation while in Pennsylvania can be a complicated consideration. If a person needs to move, they would, of course, have to notify their probation officer. Issues can arise if a person is trying to move to a different County or to a different state. That's most often when the issue as to where a person lives would become an issue with respect to probation.
Transferring a case from one County to another in Pennsylvania is not an overly complicated process, but it is a process people when they're trying to move out of state can find themselves facing issues because, for various reasons the state where the person is seeking to move would need to approve the transfer of the case and the originating state, Pennsylvania would need to put in the request. It's through the interstate compact, and it can take 45 to 60 days. There could be instances where a person is forced to remain in Pennsylvania when it may not be to the best of their circumstances when they actually, in fact, need to get to that next state.
It can be a complicated consideration. Having an experienced Pennsylvania criminal defense attorney will help you best understand both your obligations and your rights while on probation, and they should be involved if you have any issue with respect to probation.
