(b) Cancellation must be requested by the insured individual and cannot be requested by a representative acting on the individual's behalf.

(c) An individual who cancels the insurance under this section cannot obtain the insurance again, unless the U.S. Department of State determines that it would be against equity and good conscience not to allow the individual to be insured.
