sounds like you are going out of your way to sell us here, but no one in here can help you. the recruiter that told you you would be unable to go back active duty wasn't screwing you - she was telling you the truth.
getting a lawyer, a judge, etc will be of no use to you - you are done. you had your chance, you should have focused on training. btw - i can't help but think there is somehting missing. the father of a guy in my tech school class died from a heart attack, and he was able to take emergency leave to take care of matters, and he was back in training 2 weeks later, just a class behind me....
but anyhow - you're not going back AD. at least NOT in the AF. you completed basic, therefore you are now 'prior service'. The Air Force isn't real keen on accepting its own rejects either. quite honestly i am surprised you are eligible to join the reserves.
doesn't matter if you can get it changed later or not - you're not going back active duty AF. even getting it changed is almost impossible. you can ask (to get it changed), but the only way those change is if YOU can prove the DC and RE codes you received were in error, meaning the AF did something wrong and miscatagorized you. and guess who writes the rules and requirements? yep. so unless you can prove they errored (not likely) your 'code' is not going to change.
you aren't getting a runaround. you are being told as it IS. The AF has VERY LIMITED opportunities to go back to active duty, but there are strings, and you don't come close.
Here's why: Although the AF does have 'some' PS opportunities, they are usually in very hard to RETAIN (not re-TRAIN or enlistment) positions like special forces, EOD, etc - or some other highly deployed, highly stressed career field. That's not the show-stopper. This is: In order to get one of those slots, you must already be FULLY TRAINED in that career field, to include rank, time in grade, time in service. They may flex a little on SKILL level (a 7 level can occupy a 5 level slot, a 9 can occupy a 7, but a 3 cannot occupy a 7 or 9, etc). You didn't complete tech school, so you have NO skill level in a career level to even be considered. The AF does not authorize tech school or retraining in order to fill these prior service slots - so only people fully qualified can even apply. if that wasn't enough of a hurdle, you'd still have to qualify credit wise, character wise, etc to join.
so. that's where you are. I'm not trying to be a pr!ck, i am just telling you how it is RIGHT NOW in the AF, and it is not going to happen for you. Not at this time. maybe if the needs of the service change in the future, but by then you will likely be too old to join. You are done. accept that. move on.
your options are pretty much limited to the reserves or guard right now. You can try the army, but you will likely be considered prior service, and prior service opportunities in the army is pretty much limited to joining the special forces. AD Navy? forget it. they aren't taking prior service right now (not even from the navy reserve). Marines? they fall under the navy. not likely. that leaves the AF (won't happen) and the Army.
good luck. you would need a TON of waivers, and with the AF getting smaller, and record retention and record numbers of recruits that don't need ANY waivers - i wouldn't hold my breath waiting for one.
