This article relations international migration and citizenship using a case study: the Argentine migration in Madrid (Spain) across the last three decades. The qualitative analysis of interviews with political and economic migrants offers the possibility to approach two migration flows that responses to diverging political and social contexts in origin (1976 dictatorship and 2001 crisis) and, at the same time, to show the transformation of receptions contexts. It is assumed that the migration responds to a deficit of citizenship in Argentina that is tried to get back in the receiving country. To investigate this, it focuses (i) the experiences of the interviewee before migration and (ii) the adaptation process in Spain; (iii) it thinks about the conformation of new forms of citizenship.
