There seems to be some confusion, you don't "request your final select" once a person is pro rec Y there is a list of things must be completed or met, once those are done then the FS paperwork is automatically processed by NRC, now if you are waiting on a board then yes you do have to let your recruiter know that you wish to forgo the other boards and be processed for what you were already pro rec for.
The status "awaiting FS, or awaiting FS signature" is just that a status, a person can sit in that status for days, weeks, months, or in one case years (IP), just because one person goes to that status and then has the letter arrive at the NRD in a week doesn't mean everyones will.
Ahh this is what I figured, ive done all the other paperwork. After looking through this though I thought maybe my FS was taking so long because I hadn't officially requested it, thanks for clearing that up.
