This depends on the PO's recommendation to the court and how and the violation was written up. The problem is that the original judge will decide and they are normally not happy to see the defendant back in front of them, violating the leniency previously provided. It could be a few months or the balance of the original sentence.

If he violated probation there won't be a bond, he'll have to wait to appear before the judge that issued the warrant.

Violation of parole is dumb. You put yourself at the mercy of the judge that had leniency for you. The penalty could be as stiff as having to finish the remaining months on the original sentence with no possibility of an early release. Anything less than that, he should consider himself lucky.

This has everything to do with his record while incarcerated and how well his interview goes. There are no ways to estimate how the outcome will turn out, but if he's been a model inmate and followed all the programming recommendations then he has the best possible chance at a successful result. 

Restitution means paying back the money that was "lost during the commission of the crime". If the restitution is $6,000, it sounds like she is getting a VERY good deal to avoid doing more time. Her PO seems like a reasonable, decent person. Most POs show zero tolerance for violators. We strongly recommend taking this offer and doing whatever she can to paying the fee and then keep her nose clean.

Yes, 100%. The probation was her leniency. By breaching the generosity provided by the court, she has no other options but to finish out the remaining days left incarcerated.

Once the parole is revoked, there are no more options for early release.

You will need to get permission from the Office of Probation to communicate with another felon

You will have to get permission for that. It is not a normal request, but if your boyfriend has a good job and your residence appears clean and free of drugs, alcohol and firearms you might get special approval.

We don't think so. He will most likely have to complete the remainder of the original sentence without the benefit of any relief or early release (again). It would appear he used up his chances that the judge offered at sentencing.
