I have a documented in-service event while in the reserves. It has also been listed as a Favorable Finding on multiple claims. No LOD. When I filed a claim it came back as no in-service event. I believe this is because the time has not been converted to Active Duty by a VA Form 21-6789. Does this have to happen for the VA to recognize the time, even though it has been found previously as an in-service event while Active Duty? I do have other time that was converted with a VA 21-6789 but I did not initiate it, the VA did. If it is a requirement, how do I get it done?
