In recent years, research has documented a growing feminization of migration, with focus on those specific forms of migration, such as the commercialized migration of women as domestic workers and care givers, that often result in the trafficking of women for labour and sexual exploitation. Many women who migrate lack residence permits and, thereby, receive the status of undocumented migrants. Undocumented female migrants are without any substantial legal or social protection in their host societies and, therefore, are highly subject to exploitation, violence, and health and social problems; this is a situation that obviously harms them as individuals attempting to live in a new country, but that extends beyond national boundaries in its effects, to also harm members of their families in their countries of origin. Current nationalized legal and social policy frameworks need to be sensitive to the complex and transnational nature of the living conditions of undocumented migrant women. This chapter draws attention to the precarious living conditions and complex socio-legal challenges that impact the everyday lives of undocumented migrant women in the Nordic countries, with particular emphasis on Sweden. Based on comprehensive research review of undocumented migrant women’s living conditions in Sweden, the study explores the current role of legal and social policy frameworks for providing protection to this vulnerable group. The authors argue that there is an urgent need for interdisciplinary (socio-legal) and intersectional perspectives, for studying and understanding the complexity of the intersection of power relations influencing the living conditions of undocumented women. The findings of this study, and its gender-based intersectional approach, aim to encourage further research, as well as to sensitize legal and social policy professions in their endeavours to reduce and eliminate the racialized and gender-based oppression and discrimination of undocumented female migrants in Sweden.
