Have you tried an Infopass appointment? That might be the best next step. You could also contact your Congressman's office and see if they can help you get some more information. Sometimes the Congressman's office gets results and other times not. It depends on who, what, when and where, but after this length of time waiting, I'd be wanting to try anything.

Infopass or get the ball rolling with your congressperson or Senator Mikulski's office is in order. You should be at the Baltimore office or the National Benefits Center if being waived, and the last I saw, that office should have finished April 2015 a while ago. We sent ours off in November and thought we were doomed to keep on waiting for the Baltimore timeline. USCIS just kept telling us that it was at the local office, but guess what? It wasn't and never was. The case was sent to a field office in a state we didn't even live in. We didn't find out until we received an RFE.
If I had to guess, it was either sent somewhere it doesn't belong.. or it's been misplaced. Don't be surprised either, if after all this time has elapsed, and they find the case, that they want you to get a new medical.

We responded to the RFE (completely unnecessary one) that they sent us and the approval came within days. I was happy that we got results of course, but they never could quite explain why it was there. In our case it was sent by the New Hampshire office. If you have a response from Milwaukee, then I can only imagine that you will also be waived, whenever they decide to start working on it. At least this may prompt them to get looking at it. The NH office was even further backed up than Baltimore.
I'd actually like to know if more people have experienced this issue recently.. perhaps it's some policy change they don't want to tell the public about.
