I have received an appointment to usafa, but have been waitlisted at usna, which is my top choice. I am wondering if usafa allows appointees to defer their appointment to next year (in order to do a year of civilian college and reapply to usna) without having to reapply to usafa. If not, is it frowned upon to decline an offer of appointment to usafa and reapply the following year (as a backup to usna)?
