(b)
If any eligible person pursuing a program of education, or of special restorative training, under this chapter ceases to be an “eligible person” because—
(1)
the parent or spouse from whom eligibility is derived is found no longer to have a “total disability permanent in nature”, as defined in section
3501
(a)(8) of this title,
(2)
the parent or spouse from whom eligibility is derived based upon section
3501
(a)(1)(C) of this title is no longer listed in one of the categories specified therein,
(3)
the spouse, as an eligible person under subparagraph (D) or (E) of section
3501
(a)(1) of this title, is divorced, without fault on such person’s part, from the person upon whose disability such person’s eligibility is based, or
(4)
the parent or spouse from whom such eligibility is derived based upon subparagraph (E) of section
3501
(a)(1) of this title no longer meets a requirement under clause (i), (ii), or (iii) of that subparagraph,
then such eligible person (if such person has sufficient remaining entitlement) may, nevertheless, be afforded educational assistance under this chapter until the end of the quarter or semester for which enrolled if the educational institution in which such person is enrolled is operated on a quarter or semester system, or if the educational institution is not so operated until the end of the course, or until 12 weeks have expired, whichever first occurs.
