I don't know. The intent I think is for the Air Force to accept only
"current" active duty.
I emailed a LtCol who is in the "know" r/t Air Force CRNA programs and he said they might eventually have to look at a direct commisioning CRNA program similar to the Army. My interpretation of that comment is "but, not now".
As far as the Navy, they have 100% percent of their slots filled. They aren't even looking for anyone other than active duty Navy.
This is all subject to change at the discretion of the military.
Good luck
