Schengen Information System

The Schengen Convention led to the gradual abolition of checks at the internal borders of the Schengen States, allowing free travel. To offset the security deficits resulting from the abolition of checks, the Schengen States agreed, among other things, to establish the Central Schengen Information System (SIS).

SIS contains for example data on non-EU nationals for whom an alert has been issued for the purposes of refusing entry, e.g. for having committed a criminal offence. Each Schengen state has access to this data in the form of a national information system (NSIS).

Germany’s NSIS is managed at the Federal Criminal Police Office. The Federal Criminal Police Office regularly transmits the part of the data on refusals of entry to the Federal Office of Administration which makes it available in visa procedures to authorities issuing visas and discharging responsibilities under foreigners’ law when they query the Central Register of Foreigners.
