Marriages that involve the migration of at least one of the spouses challenge two intersecting facets of the politics of belonging: the making of the 'good and legitimate citizens' and the 'acceptable family'. In Europe, cross-border marriages have been the target of increasing state controls, an issue of public concern and the object of scholarly research. The study of cross-border marriages and the ways these marriages are framed is inevitably affected by states' concerns and priorities. There is a need for a reflexive assessment of how the categories employed by state institutions and agents have impacted the study of cross-border marriages. This collection of essays analyses what is at stake in the regulation of cross-border marriages and how European states use particular categories (e.g., 'sham', 'forced' and 'mixed' marriages) to differentiate between acceptable and non-acceptable marriages. When researchers use these categories unreflexively, they risk reproducing nation-centred epistemologies and reinforcing state-informed hierarchies and forms of exclusion. The chapters in this book offer new insights into a timely topic and suggest ways to avoid these pitfalls: differentiating between categories of analysis and categories of practice, adopting methodologies that do not mirror nation-states' logic and engaging with general social theory outside migration studies. This book will be of interest to researchers and academics of Sociology, Politics, International Relations, Social and Cultural Anthropology, Human Geography, Social Work, and Public Policy. Barring one, all the chapters in this book were originally published as a special issue in the Journal of Ethnic and Migration Studies.

Based on a qualitative study on migrants of Somali origin who have settled in Europe for at least a decade, this open access book offers a ground-breaking exploration of the idea of mobility, both empirically and theoretically. It draws a comprehensive typology of the varied "post-migration mobility practices" developed by these migrants from their country of residence after having settled there. It argues that cross-border mobility may, under certain conditions, become a form of capital that can be employed to pursue advantages in transnational social fields. Anchored in rich empirical data, the book constitutes an innovative and successful attempt at theoretically linking the emerging field of "mobilities studies" with studies of migration, transnationalism and integration. It emphasises how the ability to be mobile may become a significant marker of social differentiation, alongside other social hierarchies. The "mobility capital" accumulated by some migrants is the cornerstone of strategies intended to negotiate inconsistent social positions in transnational social fields, challenging sedentarist and state-centred visions of social inequality. The migrants in the study are able to diversify the geographic and social fields in which they accumulate and circulate resources, and to benefit from this circulation by reinvesting them where they can best be valorised.The study sheds a different light on migrants who are often considered passive or problematic migrants/refugees in Europe, and demonstrates that mobility capital is not the prerogative of highly qualified elites: less privileged migrants also circulate in a globalised world, benefiting from being embedded in transnational social fields and from mobility practices over which they have gained some control.
