Keep in mind: just having the Mitchell in the [former] cadet's records ain't enough.
You have to fill out a CAPF 11 for Foundations completion/waiver due to Mitchell. Be sure to annotate that. Send it to HQ as dictated on the form/reg (IIRC, firstname.lastname@example.org
, but I could be wrong).
It will take a few days for it to get entered. *poof* [former] cadet now has Foundations.
Then you've got the ability to submit a CAPF 2 (not via eServices) for a Special Appointment UP para 3.7. I always recommend putting the justification in the remarks block, just in case you get someone in the intervening echelon(s) who missed the boat on Special Appointments, Mission Related Skills, and such. Don't make them have to go back to eServices, and say "OK, what is this guy's quals?" Make it clear: "SM Bagofdonuts is qualified for 1st Lt as a former Earhart cadet under the provisions of CAPR 35-5, para 3.7."
When I get a CAPF2 in for a special, I always look to see if the Personnel Officer or commander at the previous echelon helped me out (and helped out the echelon above) with extra info.
It never hurts to do what you can to avoid having a promotion sit for a day or two on someones [virtual] desk because they're not 100% sure what you're trying to do.
