This article examines the importance of mobility in the historical and ongoing constitution of lesbian and gay subjectivities. While the state in the past frequently sought to restrict the movement of sexual dissidents across national borders, current developments in an array of jurisdictions suggest a more permissive attitude, particularly in the case of the ‘unification’ of same-sex couples. These legal and political developments are interrogated with respect to the construction of ‘acceptable’ homosexualities and, more broadly, in terms of cosmopolitan and communitarian visions of sexual citizenship.
