Connect Unserved Americans Act of 2022 This bill modifies administration of and requirements for broadband deployment programs. Specifically, it requires the Department of the Treasury to participate in interagency activities to coordinate federally supported broadband deployment. The bill also increases the percentage (from 50% to 80%) of rural households that a project must serve in order to receive a grant or a loan to expand access to broadband for distance learning and telemedicine in rural areas.
