Just published in Racial and Ethnic Studies, this article co-authored by Bloch, Sigona and Zetter explores the entry strategies used by young people in relation to the UK immigration system and their undocumented status. Against a brief account of Britain’s regime, the paper first examines why and how these migrants come to the UK and the ways in which they entered the country. Second, it explores strategies in relation to immigration status and considers: the use of different immigration statuses; the role of the asylum system in their strategies including as an attempt to regularize status or as a route to becoming undocumented when refused asylum. Finally, the paper discusses the extent to which these young migrants have agency in their efforts to negotiate the complex and exclusionary immigration and asylum regime.
