The written notice shall be in English and in the primary language of the pupil.

(b) Any parent or guardian whose child or ward has been or will be enrolled in programs authorized pursuant to subdivision (a), (b), (c), or (d) of Section 52163 shall have the right, either at the time of the original notification of enrollment or at the close of any semester thereafter, to withdraw his or her child or ward from the program, by written notice to the principal of the school in which his or her child or ward is enrolled.
