You can apply for PC all you want.People have been released under the PC program with recommendation of dissaprove from AFPC. Its the SECAF office of personnel that makes the decision.
I got Palace chased this past June for a release in Oct. I asked for 6 months and they said no. So I asked for 2 and a half months and they said yes. Your application will be routed through your SQ/CC then your WG/CC then AFPC and then off to the secaf panel. AFPC can say no all they want, they arent the final approval authority.Maybe this has changed in the last 6 months
I was an active duty nav that went ANG and am currently waiting on UPT dates.
