How possible is it to do a second residency in the Air Force (in a very competitive field)? I have gradually come to the conclusion that I hate the field I am currently in residency for, and wish that I had gone with the other field that was lingering in the back of my mind when applying (although there were actually no slots for it that year to apply for). I have every intention of finishing my current residency, but I was wondering if programs really dislike having people do second residencies.
