[Description: This paper aims to provide a brief analysis of the Ruiz Zambrano judgment (Case C-34/09). Traditionally, the EU citizenship has been mainly construed as a status of integration into the Member States of the Union: a status of transnational integration. The basic claim developed in these pages is that, with Zambrano, the EUCJ moved away from a concept of transnational integration to one of genuine European integration, thus fostering a new vision, based on the existence of Euro-bonds.]
