do u have to be on an inmate's visitor list to visit said inmate during visiting hours, also when r visiting hours?

You also have to call 2 days in advance or they won't let you set up a visit till the next following visit

The inmate has to put you on their list themselves. Visitation is from Wednesday 6 p.m. to 9 p.m. they are 15-minute visits. Saturday from 9 a.m. till noon 15 minute visit. For the Wednesday visit you have to call by Monday at 9 p.m. to make an appointment. For the Saturday visit you have to call by 9 p.m. Thursday. You cannot have any active warrants anywhere. Even non-extraditable warrants and you cannot be on probation and parole. If you are you have to get permission from your parole officer and they have to contact the jail Sergeant to get approval to visit.

Yes and you have to call to set up a visit.
