The Immigrant Access to Health and Human Services project maps and describes the legal and policy contexts that govern and affect immigrant access to health and human services. Through a synthesis of existing information, supplemented by in-depth visits to purposively selected sites, the study aims to identify and describe federal, state, and local program eligibility provisions related to immigrants, major barriers (such as language and family structure) to immigrants’ access to health and human services for which they are legally eligible, and innovative or promising practices that can help states manage their programs.
