Enlisted Sailors must remain on active duty throughout the duration of the term of the TA funded course(s). If you are nearing your End of Active Obligated Service (EAOS) and need to have it updated, submit a copy of your reenlistment contract and/or a signed page13 (https://www.navycollege.navy.mil/docs/PG13_active_duty.doc) to the NCVEC. Submit the required documentation if your enlistment contract and EAOS will expire before the course completion date and cannot be updated in time via normal procedures.
