ABSTRACT
This chapter illustrates how migration control policies worldwide contribute in the development of a differentiated citizenship. It seeks to offer a first sketch, a broad description of a differentiation rather than a normative analysis. The chapter explores the perspective of a type of 'global' citizenship, albeit one that is formally scattered across nations and perhaps rather weak from the perspective of political theory. It also explores the existence of a 'global' migration control regime, albeit one that is decentralised. Migration control is broadly presumed to be the prerogative of states, and is therefore often referred to as immigration control. Visa requirements offer a third dimension of stratification. Visas are what give states most versatility in terms of designing a migration policy. Anti-immigration sentiment often focuses on a mix of nativist – such as ethnic, religious or linguistic – considerations about the political community or socio-political cohesion being endangered.
