This Inform presents an overview of the EMN Study on “Challenges and practices for establishing the identity of third-country nationals in migration procedures”. The Synthesis Report is available on the EMN website and is based on National Reports from 26 (Member) States. The aim of this Study is to present an overview of the challenges faced by national authorities in their efforts to reliably establish and verify the identity of third-country nationals within the context of various migration procedures – namely those related to asylum, return, legal migration channels (including both short-stay and long-stay visas and residence permits) – and of national practices to address those challenges. This study updates and supplements the 2013 EMN Study “Establishing Identity for International Protection: Challenges and Practices”.
