Methodological nationalism as an obstacle in sociological research on international migration

Globalization has evidenced the necessity to question the "methodological nationalism" as fundamental assumption of the first modernity. This question breaks the assumption that the contours of the society coincide with those of the nation-state, and it supposes an epistemological challenge for the Sociology that adopted an outline of classification of the social space that could be denominated, from its birth, state-society isomorphism. In this paper we carry out some considerations on the epistemological and methodological challenges that the international migrations suppose for the Sociology and the main practices of social empirical research that generally drag inertias and epistemological assumptions anchored in the features of the societies of the first modernity.
