The complex dynamics between the states and the immigrant influxes led to the ongoing transformation of identity and security structures. The threats of terrorism and trans-national organized crime aggravated fears of immigration, while the prospect of Turkey and other Western Balkans states’ accession to the EU highlighted the importance of identity securitization and led to a permanent employment of identity in the migration-security logic.This paper deals with some of the key issues on how identity innovates the migration-insecurity causality relation, conferring it flexibility and referential value both at a sub- and a supranational level. In this paper, our attention is retained by the actual and potential political, social and security implications arising from the transformation of identity into a referent object of security, while identifying ways to address these consequences at a national or community level.
