How long does it take for a probation violation to be reported across state lines? Border to border.

Don't quite understand the question. Do you mean how long does it take for the probation office to be notified of the probationer's new arrest in another state?

First of course the person who violates is suppose to notify their PO, most people on probation get into more trouble because they don't call and notify their PO about the trouble. Often the PO finds out about it when the PO runs routine checks on their background

After a crime is done, the report goes back to the PO department ( state) and depending on many factors can take some weeks to flilter to the PO

How can I get off probation if I'm 17 and I ban on probation for 11 months and I have 7 more months to go
