I was pro-rec in Feb, took new prt that week and had everything ready to be sent. Kinda tweddling thumbs with my OR the last almost two months just waiting to hear back, then...
I'm assuming that since you took the prt that you passed meps (and what exactly is the 'new' prt?) Did you sign more papers for them to do the security clearance? That will take a lil bit to get going. Any med waivers that you're waiting on? Those can all hold you back.
And don't sweat waiting a long time - got my PR in Oct08 and I'm still waiting for that FS letter... damn being med down.
