Sorry no one has responded to you. Sometimes questions get overlook or people may not know how to respond.
A return to duty finding will be based on how well you can do your job, as well as your Commander and doctor's recommendations. Unfortunately, some PEBLOs are overworked and not able to reply right away. Even more unfortunate, some PEBLOs just don't care and never respond. The PEBLO will usually notify you by e-mail or phone. You can always call or stop in and try to talk to your PEBLO to get an update. Just be respectful and remember they're just trying to do their job, and don't need 15 people nagging them for a status update everyday.
