He will have to definitely submit the Curtailment paperwork through S1. he needs to ensure that he specifically states that this was a prior commitment of the branch from when he enlisted, prior to the decision to rescind the language requirement (waive for lack of a better word). Sometimes when you walk into S1 and confer with a SPC and say, "What do I need to do to file a curtailment to go to DLI?", they will take you for just that. He has to ensure that he lays it out for them in black and white and that "all four corners of the box are shaded with a dark marker" (i.e. be specific in addressing your needs.).
There is no reason why they cannot push the paperwork. If I am correct, once S-1 files the paperwork, it simply goes to G-1 anyways, and then to HRC. With everything running digital nowadays, it isn't a long process like it used to be.
Tell him to go in and readdress the issue. If he is unsuccesful on the next attempt, involve the immediate chain and go to the NCOIC of the S-1 shop. Sometimes people get caught up in these conundrums that appear to be a lot fuzzier than they are. Believe me, I am in a detachment of 20 Active Duty personnel with a HQ in MDW and administratively assigned to USARPAC. I know the pain of paperwork. Wish him the best of luck.
If you guys know anything about the 163rd MI at Hood, let me know. I am headed that way in November.
