This article explores the social relevance of the nationalization of foreign migrants in Chilean society. In particular, we explore the extent to which the naturalization of immigrants, as an administrative-legal capitalization given the recognition of rights, is also associated with social capitalization that goes beyond the formal scope, the individual level and, eventually, beneficial aspects, both for the Group as well as for the host society. For this, the associative and social practices of nationalized and non-nationalized migrants were analyzed from a subsample of the CASEN survey (2015). The results obtained show that among the nationalized migrants, given their levels and patterns of social participation, there is a greater social capitalization with respect to non-nationalized migrants.
