    Sec. 5-9. Except as herein provided, no person shall be registered unless he applies in person to 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 Deputy Registrars, the Judge of Registration, or an Officer of Registration, 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 place of residence, name, 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 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 in writing notify such applicant to appear before the County Clerk to furnish further proof of his qualifications. 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 in such township, city, village or incorporated town and whose registration 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 ........ ward of the City of .... or of the ......... District ......... Town of .......... (or to the County Clerk of .............) and ............ County; that said Board or Clerk refused to complete my registration as a qualified voter in said precinct, that I reside in said precinct (or that I intend to reside in said precinct), am a duly qualified voter and entitled to vote in said precinct at the next election.

    All such applications shall be presented to the County Clerk by the applicant, in person between the hours of nine o'clock a.m. and five o'clock p.m., on Monday and Tuesday of the third week subsequent to the weeks in which the 1961 and 1962 precinct re-registrations are to be held, and thereafter for the registration provided in Section 5-17 of this Article, all such applications shall be presented to the County Clerk by the applicant in person between the hours of nine o'clock a.m. and nine o'clock p.m. on Monday and Tuesday of the third week prior to the date on which such election is to be held.
