Reposting this in a slightly different version. Last year, several of us also referred to this limbo status as being bubble-sitters. Everyone who has received a TWE at this point knows where they're not going to be come June 24th.
This waiting time on the bubble is harder, because you just want to know something with a level of certainty. USAFA wants to fill the class too. You're on the bubble now because USAFA is waiting for answers to previously made offers or for them to expire. You're in a group of candidates they like. There are a finite number of slots, they want to fill them all, hopefully you'll see the offer in your portal soon. Remember the same four possibilities currently exist that existed once you became a 3Q candidate - an appointment, USAFAPS, FFS or TWE. One of these will show up no later than June 22nd or 23rd.
Keep in mind just being here is a testament to you being an excellent candidate. You've demonstrated the work ethic, leadership, interview/personal skills and perseverance to have come this far. No matter the result, you have great things ahead in your life. You're in a good spot, you just have to wait a little longer, and yes that is disappointing. Continue to work on plans B,C,D, etc. and check portal every couple of days. You'll be off the bubble soon enough. Good luck!
