This article discusses the position and agency of Romani migrants. It argues that different states often irregularize the status of Romani migrants even in cases where it should be regularized due to their de jure citizenship. This irregularization is possible because of their position as semi-citizens in their ‘states of origin’. Yet, Romani migrants are not mere passive observers of these practices, but react to their irregularized migrant statuses. In doing so, they redefine their national and European citizenships. This article centres around two case studies to analyse the position and agency of Romani migrants The first is Roma with European Union (EU) citizenship and the second is post-Yugoslav Roma without EU citizenship.
