I received an LOA from USAFA in mid-November, and then in the following month on December 19th, I received the formal letter of appointment. Both of these were received on my portal, with no hard copy mailings from USAFA as of today. After lots of cross-country trips and navigating these forums, I came to my decision on February 25th and accepted my appointment to USAFA. I have received no further confirmation rather than the message on my portal saying "Welcome to the United States Air Force Academy" and just below "Offer accepted". I reached out to Team Blue on March 5th and received a generic response stating, "You will receive a certificate in the mail". There was no eta or any further information regarding when this certificate may arrive. I am wondering, when is it common to receive this certificate of acceptance? I have not denied my acceptance to other SA and universities, as I want to receive this certificate before I do so, in case anything happens.
