(Authority: 38 U.S.C. 3202, 5303A)

If he or she wishes to receive educational assistance based upon this service, the veteran must elect the chapter under which he or she will receive benefits.
(2) If a veteran elects to receive educational assistance under 38 U.S.C.

Negotiation of an educational assistance check provided under either 38 U.S.C. chapter 32 or 10 U.S.C. chapter 1606, but based upon a period of service which preceded the period for which an election was made, will not serve to make the election irrevocable.
