A Long Time.
Actually, In your case should be about 6 months to a year. you will need to compose a Aeronautical review Board Waiver package, consisting of about every piece of Navy training you ever did, to include your ATJ Summary, every checkride, every promotion order, Every thing in your Natops jacket, copy of your Logbook, etc. Find another guy who has gone thru the process in the unit you're going to and ask to see his, and put it together just like it. If not, find another unit with someone who has crossed into the blue, and call them up. There is an AF instruction about this, your unit should know about this.
You'll also need a AF physical from a AF force Flight surgeon, but it will be more like a NAMI whammi, rather than the gentleman's senior o-3 physical you're getting now. Lower your cholesterol now, if its high, the AF has a hard on for the stuff. Polichosanal and Red Yeast Rice work, with a no red meat diet.
Other wise I'd say you're making a good choice. No up or out, Reserves and guard is almost like the Navy, and way less politics than Active duty.
