I should have also added that once he knew he was within the allotted timeframe (which was mid-March, for him) he gathered all supporting med docs and sent them to his DODMERB case manager. He did not wait for an AMI request to come for them. He said he knew what they would be asking for because there was a way to look it up somehow using the single disqualification code. Once he knew exactly what that was, he requested such documents from his doctor and sent them in to DODMERB. His case manager responded within a day and said they had received them and would have them available for the waiver authority to view. Navy must have viewed them within the next week and his portal changed to waiver granted.
So, in his case, he knew he had met the criteria and took it upon himself to supply to documents that were needed. I'm sure each waiver case is different. But, if you think you'll need to supply AMI that you already have, you might want to send it to your case manager.
