Being off the PSP registry when your time is done allows you to go anywhere you desire.
But if the PSP review your case and decide to do a voluntary cessation due to your review – they put a detriment statement on the letter saying that you are only off the PSP registry – if you visit another state and you plan to stay more than their SO registration requires – you would have to register in the visited state.
There is a case that where the PSP reviewed J.J.M. and he visited another state and did not register with the other state and he thought he was off all state requirements to register.
The PSP puts on the letter they give you instructions to warn about visiting other states. If you don’t plan to visit other states it is not a big issue.
