When the results memo is released those are official results. Some people think the FINSEL paperwork is official and the results memo isn't, but that's a misconception. Your selection on the memo is official, the paperwork that comes later is just part of the process.Lets get it!!!
A word to the wise for everyone though, my recruiter said these are all "unofficial results" and have the potential to change. Don't 100% count your chickens before getting a final select letter!
I'm not sure why they would change something from now until the results memo but I suppose you could take the releases today with a grain of salt. Once you see your name on the results memo that's pretty set in stone unless you ruin it for yourself as mentioned previously about the clearance investigations.
