Carriers transporting third-country nationals by air, sea, or land to the Schengen area are required to take all necessary measures to ensure that these individuals hold the travel documents needed for entry into the Schengen States.

On 21 and 22 May 2025, the European Migration Network’s Return Experts Group (EMN REG) convened a two-day workshop, hosted by the Belgian Immigration Office and EMN Belgium. The event brought together 50 participants from EU Member States, EU agencies (including Frontex and the EU Asylum Agency), civil society organisations, and international organisations. The workshop focused on the development and implementation of effective alternatives to detention (ATDs) within the EU’s migration and return systems.
