SIS use for return of illegally staying third-country nationals

This procedure aims to improve how the Schengen Information System (SIS) is used to identify and return third-country nationals who are staying in the EU illegally. By enhancing data sharing and alerts, the EU seeks to make the return process more efficient and secure across member states.

This affects non-EU citizens residing illegally in the Schengen area and the border authorities responsible for migration control and deportations.
