Local agencies participating in the program under this section shall notify persons of their eligibility or ineligibility for the program within twenty days of the date that the household, during office hours of a local agency, personally makes an oral or written request to participate in the program. The Secretary shall establish a shorter notification period for categories of persons who, due to special nutritional risk conditions, must receive benefits more expeditiously.

State agencies may provide for the delivery of vouchers to any participant who is not scheduled for nutrition education and breastfeeding counseling or a recertification interview through means, such as mailing, that do not require the participant to travel to the local agency to obtain vouchers. The State agency shall describe any plans for issuance of vouchers by mail in its plan submitted under paragraph (1). The Secretary may disapprove a State plan with respect to the issuance of vouchers by mail in any specified jurisdiction or part of a jurisdiction within a State only if the Secretary finds that such issuance would pose a significant threat to the integrity of the program under this section in such jurisdiction or part of a jurisdiction.
