Background

Serviço de Estrangeiros e Fronteiras (SEF) was Portugal's national immigration and border police service until its dissolution on 1 October 2023, part of a wider reorganisation of the country's migration architecture. Its migration and asylum functions, along with a substantial unresolved caseload, were transferred to a new civilian body, Agência para a Integração, Migrações e Asilo (AIMA), while border and criminal-investigation duties moved to other security services.

SEF's most consequential legacy is administrative rather than operational: AIMA absorbed between 40,000 and 60,000 unresolved residency cases from the dissolved service, a backlog that has continued to shape Portugal's immigration bureaucracy years after SEF itself ceased to exist. Reporting through 2026 on AIMA's strikes, case-clearance rates and court reforms traces back, in part, to this inherited load.

As a defunct organisation, SEF no longer takes actions, issues rulings or accrues new events in its own right. Its relevance today is historical: it is the predecessor whose unfinished caseload explains why its successor agency remains under sustained pressure.

Recently resolved

Has Portugal cleared the immigration backlog it inherited from SEF?
Not fully. AIMA reported 525,000 files decided, 763,000 appointments completed and 473,000 positive outcomes by 2 June 2026, but immigration lawyers still call the government's end-2026 clearance pledge offensive, with no separate breakdown for D8 digital nomad visa cases.Source: AIMA / immigration lawyers
Did Portugal create specialised courts for immigration cases?
Yes. Portugal's Council of Ministers approved diplomas on 23 July 2026 creating specialised immigration and asylum Administrative Courts and proposed ending Lisbon's exclusive jurisdiction over lawsuits against AIMA.Source: Portugal Council of Ministers
How many immigration cases are pending in Portugal's courts?
As of July 2026, Portugal's Council of Ministers cited 152,000 pending cases in first-instance administrative and fiscal courts, a 34 per cent resolution rate, and a 216 per cent rise in case volume between 2023 and 2024.Source: Portugal Council of Ministers
