In migratory circulations, migrants' social position is changed with each mobilization in the societies of departure and arrival. This chapter outlines the contours of a sociology of inequalities and migrations. It deals with the conditions of migrant workers in subaltern situations in international cities, based on the ethnicization of labor markets, the globalization of care and platform capitalism. The chapter shows how inequalities in migratory paths accumulate, grow or are maintained in a multisituated process, where migrants' resource repertoires are constantly recomposed, giving rise to a cosmopolitization and a social differentiation of biographies. It discusses the grammars of social and moral recognition that migrants must learn in each place to “take their place” with their experiences, skills and qualifications. The chapter shows how “forced migrants” can be confronted with this extreme test of inequality, namely expulsion.
