Which state? there are two dozen Jefferson County's

In some cases like most county jail, you only need an ID. If you are going to state or federal inmate visitation you will need to fill out an application and gain approval before being allowed to visit. 

Sadly, it probably does. Criminal history plays a big part whether prison time is included in a sentence and for how long.

Parole is only available if the judge stated so in the Judgment and Commitment Order. Normally, two year sentences are not ones with parole attached, but you could call the counselor and ask if there is a possibility of parole.

You might be able to get away with a county visit if their vetting procedures are not as strict. We don't know the facility you are going to, so we cannot offer anything further. If you are not permitted to visit in the prison, why would they let you visit in the county jail? Unless they don't know why you are being denied, you could try and see what happens.

They might, every county is different. If you suspect that you have a warrant, we would not risk it. You could send someone you know to visit first and then ask them the procedure. Just a thought, why not clear up the warrant with a phone call and arrange to clear your name?

If you are saying your inmate assaulted a guard to keep him from finding their hidden cellphone, they have a huge problem. Cell phone possession by an inmate carries a five-year federal charge. They do not often up the charges, they usually throw the inmate in the SHU for 6 months to a year then transfer them to a higher security facility. But, the assault of an officer changes everything.

Yes, if he says they have email they probably do. If it is a federal inmate, the website is Corrlinks.com, but he has to send you an invitation first.

Depends on who he pissed off. They could see him the next day or he could sit for weeks if he did comething that really made the judge or the prosecutor angry.

This depends on the charge. It certainly shows poor judgment violating with one time left... it's almost as if they were doing it on purpose.
