G-845 Supplement, Document Verification Request Supplement
The Form G-845 is used to verify the immigration status of an applicant for federal state or licenses. An agency that is responsible for an applicant or sponsorship can file the Form G-845 to request immigrant status verification information and the agency also needs to be registered with the U.S. Citizenship and Immigration Services’ (USCIS) and the Systematic Alien Verification for Entitlements (SAVE).
Any agency that has completed a Memorandum of Agreement (MOA) which is a written document about a partnership, with the USCIS SAVE Program can file the Form G-845 Supplement if the agency needs additional information that is not mentioned on the Form G-845 Verification to administer some benefits. You can check with the SAVE program if you are not sure whether you can use the supplement.
