This study examines the often-overlooked underside of healthcare and nursing by foregrounding the socioeconomic and cultural dynamics shaped through intersections of class, ethnicity, and international boundaries. A significant proportion of migrant nurses in the Gulf and the United Kingdom belong to Kerala’s Syrian Christian community. The study argues that their circular mobility between southern India and temporary employment in the Gulf facilitates the emergence of new migration corridors to other global destinations. Drawing on anthropological and historical scholarship, the analysis situates nurses within competing pressures and aspirations across the home-host divide, framed through the figure of the cosmopolitan migrant. These dynamics shape capacities, aspirations, and tensions as nurses negotiate traditional values, modernity, expectations, duties, and altered roles. In particular, the study illuminates stepwise migration alongside emergent caste and class contestations in the Gulf and the United Kingdom.
