This research examines how EU externalisation migration policies construct masculinity. Through a critical analysis of EU externalisation policies and an empirical investigation of the experiences of single migrant men of colour, the study aims to uncover the legal and practical implications of gendered policies on asylum rights. By using an intersectional masculinity lens, the research seeks to understand how gender and other social characteristics, such as race, shape the vulnerability of single migrant men of colour and how this vulnerability is reflected in policy and case law. These results are compared with the lived experiences of masculinity and vulnerability of single migrant men of colour. The project aims to make an important contribution to legal scholarship by filling the existing gap in research on masculinity within migration law and offering insights into the experience of single migrant men of colour with the construction of their masculinity in relation to EU externalisation policies.
