This article discusses the effects of the 24 year-old rule in Denmark utilising Foucault’s understanding of the ‘subject’ within a governmentality framework. The 24 year-old rule is a good example of how a gendered knowledge about immigration becomes a reality that steers biopolitics, enables practices of normalisation and subjectifies immigrants in various ways. The article foregrounds the subjectivity of immigrant women through a narrative analysis of the constitution of the subject within discourses and in an asymmetrical relationship to power in governance. This analysis reveals the complexity of empirical interactions between the ideational structure of legislative measures and personal meanings expressed by immigrant subjectivities. While I illustrate certain modes of subjectification in relation to the 24 year-old rule, I emphasise the ways subjects employ certain identity strategies by resisting, reworking or contributing to the practices of normalisation.
