Following the dissolution of the Serviço de Estrangeiros e Fronteiras (SEF) in late 2023, the Polícia de Segurança Pública (PSP) has assumed responsibility for border control at Lisbon Airport. The current procedure involves document-verification software followed by interviews with trained agents to determine eligibility for entry into the Schengen Area. Travelers failing to meet criteria are held in a designated area colloquially known as the “SEF room”. In an expansion of enforcement capabilities, the PSP has entered into operational cooperation with Ireland’s national police, An Garda Síochána. During the first year of this collaboration, spanning July 1, 2025, to June 30, 2026, authorities identified 206 irregular travel cases at Humberto Delgado Airport. These cases included 113 instances of forged or counterfeit documents and 76 passengers lacking necessary visas for Ireland. The initiative includes a liaison officer from the Garda National Immigration Bureau stationed at the airport to assist with passenger analysis. ## Timeline ### 2026-08-13: Lisbon Airport: Police cooperation detects 206 irregular travel cases Police cooperation between Portugal and Ireland detected 206 irregular travel cases at Lisbon Airport in one year, primarily involving forged documents and visa irregularities. 3 sources. https://clstr.news/cluster/lisbon-airport-police-cooperation-detects-206-irregular-travel-cases ### 2026-08-07: Portugal's PSP oversees Lisbon Airport border checks amid new procedures Portugal's PSP now controls Lisbon Airport border checks, using document‑scanning software and interviews; migrants may be held for hours in a cramped “SEF room” as they await Schengen entry decisions. 2 sources. https://clstr.news/cluster/portugals-psp-oversees-lisbon-airport-border-checks-amid-new-procedures --- Cite as: Lisbon Airport immigration enforcement and border control.
