In the struggle for access to political rights and full citizenship in their countries of destination, migrants are frequently faced with arguments remanding them to the traditional mechanism of nationalization or naturalization, by means of which their situation is resolved through inclusion based on a political topos defined in national terms. This article explores some subjectivation processes involved in the choice/decision of whether to become naturalized (or not) on the part of migrants who define themselves as political subjects. For this purpose, the article analyzes a series of interviews of members of a network of migrant leaders in Argentina from a post-foundational perspective, showing the nuances in their conceptions regarding the possibility of post-national citizenship, and some of the paradoxes of political identification processes in the current context of human mobility.
