Except as herein provided, no person shall be registered, unless he applies in person to a registration officer, answers such relevant questions as may be asked of him by the registration officer, and executes the affidavit of registration. The registration officer shall require the applicant to furnish two forms of identification, and except in the case of a homeless individual, one of which must include his or her residence address. These forms of identification shall include, but not be limited to, any of the following: driver's license, social security card, public aid identification card, utility bill, employee or student identification card, lease or contract for a residence, credit card, or a civic, union or professional association membership card. The registration officer shall require a homeless individual to furnish evidence of his or her use of the mailing address stated. This use may be demonstrated by a piece of mail addressed to that individual and received at that address or by a statement from a person authorizing use of the mailing address. The registration officer shall require each applicant for registration to read or have read to him the affidavit of registration before permitting him to execute the affidavit.
One of the registration officers or a deputy registration officer, county clerk, or clerk in the office of the county clerk, shall administer to all persons who shall personally apply to register the following oath or affirmation:
"You do solemnly swear (or affirm) that you will fully and truly answer all such questions as shall be put to you touching your name, place of residence, place of birth, your qualifications as an elector and your right as such to register and vote under the laws of the State of Illinois."
The registration officer shall satisfy himself that each applicant for registration is qualified to register before registering him. If the registration officer has reason to believe that the applicant is a resident of a Soldiers' and Sailors' Home or any facility which is licensed or certified pursuant to the Nursing Home Care Act, the Specialized Mental Health Rehabilitation Act of 2013, the ID/DD Community Care Act, or the MC/DD Act, the following question shall be put, "When you entered the home which is your present address, was it your bona fide intention to become a resident thereof?" Any voter of a township, city, village or incorporated town in which such applicant resides, shall be permitted to be present at the place of any precinct registration and shall have the right to challenge any applicant who applies to be registered.
In case the officer is not satisfied that the applicant is qualified he shall forthwith notify such applicant in writing to appear before the county clerk to complete his registration. Upon the card of such applicant shall be written the word "incomplete" and no such applicant shall be permitted to vote unless such registration is satisfactorily completed as hereinafter provided. No registration shall be taken and marked as incomplete if information to complete it can be furnished on the date of the original application.
Any person claiming to be an elector in any election precinct and whose registration card is marked "Incomplete" may make and sign an application in writing, under oath, to the county clerk in substance in the following form:
"I do solemnly swear that I,...., did on (insert date) make application to the board of registry of the.... precinct of the township of.... (or to the county clerk of.... county) and that said board or clerk refused to complete my registration as a qualified voter in said precinct. That I reside in said precinct, that I intend to reside in said precinct, and am a duly qualified voter of said precinct and am entitled to be registered to vote in said precinct at the next election.
(Signature of applicant)............................. "
All such applications shall be presented to the county clerk or to his duly authorized representative by the applicant, in person between the hours of 9:00 a.m. and 5:00 p.m. on any day after the days on which the 1969 and 1970 precinct re-registrations are held but not on any day within 27 days preceding the ensuing general election and thereafter for the registration provided in Section 4-7 all such applications shall be presented to the county clerk or his duly authorized representative by the applicant in person between the hours of 9:00 a.m. and 5:00 p.m. on any day prior to 27 days preceding the ensuing general election. Such application shall be heard by the county clerk or his duly authorized representative at the time the application is presented. If the applicant for registration has registered with the county clerk, such application may be presented to and heard by the county clerk or by his duly authorized representative upon the dates specified above or at any time prior thereto designated by the county clerk.
Any otherwise qualified person who is absent from his county of residence either due to business of the United States or because he is temporarily outside the territorial limits of the United States may become registered by mailing an application to the county clerk within the periods of registration provided for in this Article, or by simultaneous application for registration by mail and vote by mail ballot as provided in Article 20 of this Code.
