Earlier this month, eight EU member states publicly called on the bloc’s leadership to tighten visa regulations for Russian citizens who served in the country’s war in Ukraine. In a letter to European Council President António Costa and European Commission President Ursula von der Leyen, leaders including German Chancellor Friedrich Merz and Polish Prime Minister Donald Tusk warned that the war was creating longer-term internal security risks for the Schengen free-movement area, and argued that once demobilised or rotated out of the war zone, Russian soldiers might attempt to travel to the EU, where they could potentially contribute to a rise in organised and violent crime.
