I received a nomination from Senator Frist in TN for USNA. I didn't think anything was happening, so I called Frist's office and asked for a nomination to USMMA too. They said sure, and added it on.
Well a couple of weeks later I also received a nomination from Rep. Clement's office to USMMA (and maybe USNA, although now, 12 years later I can't remember). I had interviewed with both offices but assumed that because I hadn't heard anything from the Congressman's office, I wasn't going to get a nomination.
If you want it, don't be afraid to ask for it. Or, if you are more patient than I was, it could also just happen and it's just stuck in paperwork.
Now, looking back, not sure if it was right for me to call, but then, in the end, you are advocating for yourself before you're part of "the team."
