Such application form for the admission of an elector (A) shall be subject to the approval of the Secretary of the State, (B) shall not include any provisions for the witnessing of the application, and (C) shall contain a statement that (i) specifies each eligibility requirement, (ii) contains an attestation that the applicant meets each such requirement, and (iii) requires the signature of the applicant under penalty of perjury. The Commissioner of Motor Vehicles shall accept any such completed application for admission which is submitted in person, by mail or through an electronic system pursuant to subdivision (2) of this subsection. Except as provided in said subdivision, the applicant shall state on such form, under penalty of perjury, the applicant's name, bona fide residence address, date of birth, whether the applicant is a United States citizen, party enrollment, if any, prior voting address, if registered previously, and that the applicant's privileges as an elector are not forfeited by reason of conviction of a felony. No Social Security number on any such application form for the admission of an elector filed prior to January 1, 2000, may be disclosed to the public or to any governmental agency. The commissioner shall indicate on each such form the date of receipt of such application to ensure that any eligible applicant is registered to vote in an election if it is received by the Commissioner of Motor Vehicles by the last day for registration to vote in an election. The commissioner shall provide the applicant with an application receipt, on a form approved by the Secretary of the State and on which the commissioner shall record the date that the commissioner received the application, using an official date stamp bearing the words “Department of Motor Vehicles”. The commissioner shall provide such receipt whether the application was submitted in person, by mail or through an electronic system pursuant to subdivision (2) of this subsection. The commissioner shall forthwith transmit the application to the registrars of voters of the applicant's town of residence. If a registration application is accepted within five days before the last day for registration to vote in a regular election, the application shall be transmitted to the registrars of voters of the town of voting residence of the applicant not later than five days after the date of acceptance. The procedures in subsections (c), (d), (f) and (g) of section 9-23g which are not inconsistent with the National Voter Registration Act of 1993, P.L. 103-31, as amended from time to time, shall apply to applications made under this section. The commissioner is not an admitting official and may not restore, under the provisions of section 9-46a , electoral privileges of persons convicted of a felony.
