So I just asked my roommate who is currently in ABOLC and ADSO for a post and this is what he said, you should be finding out if the ADSO was approved around when your orders for BOLC are cut which will be like April for spring grads if its anything like last year. However since IBOLC and ABOLC are PCS insteady of a TDY, they will not have your final duty station on them. Those orders are cut about halfway though BOLC and untill those orders have been written your ADSO has not offically gone though and is still subject to change. Those who did not ADSO did not find out their duty location till about halfway though BOLC (however they went though during the government shutdown and that might have dealyed the results). If you are not armor or infantry your BOLC orders will have your duty location on them.
