The Secretary shall by letter advise each veteran at the time of the veteran’s discharge or release from active military, naval, air, or space service (or as soon as possible after such discharge or release) of all benefits and services under laws administered by the Department for which the veteran may be eligible. In carrying out this subsection, the Secretary shall ensure, through the use of veteran-student services under
section 3485 of this title, that contact, in person or by telephone, is made with those veterans who, on the basis of their military service records, do not have a high school education or equivalent at the time of discharge or release.
