Based on an analysis of in-depth interviews carried out with immigrant domestic workers - Dominican women in Madrid and Mexican women in New York - this article seeks to highlight patterns of interaction in three key analytical dimensions of transnational family life: domestic reproduction, motherhood and caregiving, and emotional relationships. Despite important similarities in the patterns of interaction, certain key differences emerge as a result of different family structures in the two countries of origin, patterns of international migration, and the migration policies of Spain and the United States as host countries.
