Understanding AIMA Portugal
What is the role of AIMA?
AIMA is the Portuguese government body responsible for all matters related to the legal residency of non-EU/EEA/Swiss nationals (and for EU/EEA/Swiss citizens after five years of legal residency).
If you fall into this category, AIMA controls whether you can live in Portugal long-term. Their responsibilities include:
- Issuing Residence Permits: AIMA decides who qualifies for an initial residence permit.
- Renewing Residence Permits: These permits are not permanent; AIMA approves or denies renewals (although, as detailed below, the IRN now handles most renewals).
- Family Reunification: AIMA processes applications for legal residents to bring their families (spouses, children, and dependent parents) to Portugal.
Essentially, if you are not a citizen of an EU/EEA country or Switzerland, and you intend to live in Portugal, you must obtain a visa to move to Portugal, and when arriving in Portugal, a residence permit, and your journey will involve AIMA, directly.
What services does AIMA provide?
AIMA Portugal provides (and coordinates) services in three main areas: immigration administration, asylum/international protection, and migrant integration, i.e., the “administrative side” of what SEF Portugal used to do, plus integration functions that previously sat with the High Commission for Migration.
Immigration and residency administration (the main “AIMA” work)
AIMA is responsible for managing foreigners’ legal stay in Portugal, including:
- Entry-and-stay control (administrative) and extensions of stay.
- Granting/processing residence permits and handling residence cards, including:
- Residence cards and permanent residence cards for non-EU family members of EU citizens
- Permanent residence certificates for EU citizens
- Residence permits for UK nationals covered by Brexit arrangements
- Online and in-person service channels, including contact center support and service counters (“Lojas”), plus digital forms/requests that AIMA publishes on its site.
Residence-permit renewals (how it works in practice)
Renewals have been shifting between channels as the system is reorganized. As of the Justice Ministry’s service guidance, online renewal is routed through AIMA’s Renewals Portal (Portal das Renovações), and (importantly) the same guidance states that from 1 August 2025 the IRN no longer has competence to conduct in-person appointments for residence-permit renewals.
Asylum and international protection
AIMA is also the competent body for international protection/asylum processes, and the government has described a dedicated multidisciplinary approach for managing and monitoring these cases through to integration.
Integration and inclusion services (beyond paperwork)
AIMA also absorbed many integration functions, including work aimed at:
- Reception and integration of migrants, including coordination with local integration support structures.
- Combating racism and discrimination, promoting intercultural/inter-religious dialogue, and broader social-cohesion initiatives.
- Practical public-facing initiatives on AIMA’s site such as Portuguese-language learning resources and other integration-oriented information hubs.
Equality-of-rights requests (specific legal status workflows)
AIMA also notes that requests related to granting “equal rights and duties” status (and certain political-rights recognitions) are initiated via AIMA central/regional services, with final granting tied to the relevant government area.
What AIMA does not do anymore (boundary lines after SEF Portugal)
To avoid wasted effort, it helps to know what moved elsewhere:
- Border control/law enforcement at borders: transferred to GNR (land/sea) and PSP (airports).
- Investigations into illegal immigration/trafficking: Polícia Judiciária (PJ).
- Passports for foreign citizens (and related issuance): assigned to IRN in the government’s restructuring plan.
When was AIMA created?
AIMA was created in law on 2 June 2023, by Decree-Law no. 41/2023.
It began operating / started its functions on 29 October 2023, when the SEF transition took effect.
What was SEF Portugal?
SEF Portugal was the Serviço de Estrangeiros e Fronteiras (Foreigners and Borders Service), Portugal’s former immigration-and-borders police authority.
In practical terms, SEF combined two roles:
- Border control and enforcement: monitoring entry/exit at borders and carrying out immigration inspections and enforcement actions.
- Immigration administration: handling key “in-country” immigration processes such as issuing residence permits (and related procedures) for foreign nationals living legally in Portugal.
What happened to SEF?
Portugal extinguished/abolished SEF as part of an immigration reform, with the transition taking effect on 29 October 2023.
A new body, AIMA Portugal (Agência para a Integração, Migrações e Asilo), took over SEF’s administrative/immigration and asylum competences (and also absorbed integration functions that were previously elsewhere).
Where SEF functions went?
After the reform, responsibilities were redistributed, generally separating “service/administration” from “policing/enforcement”:
- Administrative immigration and asylum → AIMA
- Border policing (by location/type of border) → security forces such as PSP and GNR (with later institutional developments inside PSP for foreigners/borders).
- Criminal investigations related to serious immigration crime (e.g., trafficking) → criminal police structures (commonly referenced as moving away from SEF as part of the separation model).
Why SEF was reformed?
The reform was widely linked to long-standing criticism of delays and inefficiencies, and it was accelerated by public outrage following the death of an Ukrainian citizen in SEF custody in 2020, which intensified calls for structural change.
