This article provides an overview of some of the major topical areas in the study of im/migrant health relevant for applied and practicing anthropologists. It illustrates the conceptual, methodological, and theoretical insights they have contributed to the discipline as a whole. Topics include the intersection of health care and immigration policy, access to services, charity care and free clinics, cultural competency, medical pluralism, reproductive health and citizenship, communicable disease, the acculturation concept, and “illegal” status as a form of health disparity. These issues are highlighted using both U.S. and comparative international research literature, with a special focus on unauthorized im/migrants. Finally, this article suggests an agenda for future work in the field of im/migrant health for applied and practicing anthropologists.
