This article examines how three major French cities designed their immigrant incorporation policies in the early twenty-first century. While political and administrative structures are similar in these cities, the favoured approaches - integration, equality, diversity - and the importance assigned to the issue of migration differed. Four factors explain the local shape of immigrant incorporation policies: the relationship with national authorities, the mobilization of European opportunities, the capacities of civil society, and the career paths of policy officers. This qualitative research provides insights into the “local turn” of migration policy in practice. It further illustrates how French cities may overcome a national model, although their fight against ethno-racial inequalities remains weak and inconsequent.
