You'll likely have to wait in LA if/until the compact is accepted by the recipient state, this process can take weeks to months (took 3 months for me), the most important thing to them was knowing I had an actual physical address to live at if the transfer was accepted. If you are accepted, you'll have to show up to report at your destination probation office within hours of arriving to your new destination. In my case, they wanted to UA me immediately, they issued me the riot act, and explained if I screwed up one bit in their jurisdiction I would be returned to my original state to serve the remainder of my probation there. Within a month, I was reclassified under their system, and reduced to the lowest tier of offender, in which case I was only required to mail in monthly reports to my probation officer. Good luck.
