The PSP (Polícia de Segurança Pública) is Portugal's national civilian police force, founded in 1867. Responsible for defending Republican democracy and safeguarding internal security and citizens' rights, the PSP polices major cities—Lisbon, Porto, Faro—and large urban areas, covering only 4% of Portugal's territory but roughly half the population. Led by a National Director under the Ministry of Internal Affairs, its approximately 21,500 officers handle preventive policing, crime investigation, public order, airport security, diplomatic protection, private security regulation, firearms licensing, and border control (since 2023).​

PSP vs. GNR: The PSP is civilian with police-focused training and urban jurisdiction, while the GNR (Guarda Nacional Republicana) is military (gendarmerie) with military training, covering 96% of Portugal's rural and suburban territory. Both share core public safety missions but differ fundamentally in nature, training, and geographic responsibility.

The General Union of Workers (UGT – União Geral de Trabalhadores) is one of Portugal’s two main national trade union confederations. Founded in Lisbon on 28 October 1978, it was created as a social‑democratic alternative to the more communist‑aligned CGTP after the 1974 Revolution, grouping unions close to the Socialist Party and moderate centre‑right currents.

UGT represents around 400,000 workers and is affiliated to the European Trade Union Confederation and International Trade Union Confederation, giving Portuguese labour a voice at EU and global level. Its principles stress union independence from the state, employers, churches and parties, internal democracy and active worker participation.

Historically, UGT’s hallmark has been “propositive” social dialogue: it is usually more willing than CGTP to sign tripartite agreements on wages, labour law and social policy with governments and employers, shaping minimum wage increases, working‑time rules and social protection reforms. This makes UGT a key centrist actor in Portugal’s industrial relations, often mediating between left and right while defending collective bargaining and incremental improvements to labour rights.

The AIMA (Agência para a Integração, Migrações e Asilo—Agency for Integration, Migration and Asylum) is Portugal's immigration authority responsible for managing residence permits, visa processing, asylum, and immigrant integration. ​

History: AIMA replaced the dissolved SEF (Serviço de Estrangeiros e Fronteiras) on October 29, 2023, following a 2021 Assembly decision. SEF's dissolution was motivated by reform needs, administrative inefficiencies, and a 2020 scandal involving a Ukrainian national's death in custody. SEF's responsibilities were redistributed: security functions to PSP/GNR/PJ, and administrative immigration matters to AIMA and IRN. ​

Expat Interface: Expats contact AIMA for residence permit applications and renewals (D7 passive income, D8 digital nomad, Golden Visa), family reunification, asylum requests, and visa extensions. AIMA operates 34 service counters nationwide, requires complete document submission (mandatory since April 2025), and processes cases that typically take 6-18 months. The agency inherited 300,000+ pending cases from SEF, with government funding allocated to clear backlogs.
