Whenever possible obtain a copy of the I-94 or other United States Citizenship and Immigration Services (USCIS) document for all aliens in the household for whom assistance is requested. If the alien does provide the requested documentation, verify the documentation with the USCIS using the Systematic Alien Verification for Entitlements (SAVE) System.
If an applicant presents an expired USCIS document or is unable to present any documentation of his or her immigration status, but the alien registration number is known, accept the applicant’s statement use the USCIS SAVE System to verify their status. If the alien registration number is unknown, refer the person to the local USCIS District Office to obtain evidence of status. Refer to 1805.020.15 Documentation and Verification of Alien or Immigrant Status of the Family Healthcare Manual – MAGI for additional information on acceptable forms of verification of alien or citizenship status.
Contact the USCIS at any time if there is any reason to question the authenticity of a document presented or the information on the document is insufficient to determine whether the alien status requirement is met.
