The PSP carried out dozens of immigration enforcement operations across the Lisbon region in 2025, reporting 94 operations that led to checks of 6,785 foreign nationals, 30 detentions and notices issued to nearly 100 people to voluntarily leave the country, according to police and multiple outlets. Some reports say detentions took place at Lisbon airport and other city locations. Immigrants affected or those uncertain about status should seek legal advice and support from NGOs; travellers should keep identity documents accessible during transit.
