16 Del. Admin. Code § 14000-14380
As a condition of eligibility under section 1137(d) of the Act, an applicant must sign a written declaration under penalty of perjury stating if he or she is a citizen or national of the U.S. or an alien in satisfactory immigration status (qualified alien or alien in lawful status). This declaration is obtained as part of the application for Medicaid. In the case of a child or incompetent applicant, an adult must sign on the applicant's behalf.
If the applicant is not a citizen or national of the United States, qualified alien, or an alien in lawful status, the declaration of citizenship or satisfactory immigration status and verification of such status is not required. If the applicant will not sign the declaration, he or she may be found eligible for coverage of emergency services and labor and delivery only.
