Why SEF Was Dissolved
The dissolution of SEF (Serviço de Estrangeiros e Fronteiras) was one of the most significant institutional changes in Portuguese immigration history. The decision came in the wake of the tragic death of a Ukrainian citizen in SEF custody in 2020, which exposed deep-seated problems within the organization including abuse of power, lack of accountability, and a culture that mixed policing functions with administrative immigration services. The incident sparked public outrage and political pressure that ultimately led to the decision to completely restructure how Portugal handles immigration.
Beyond the immediate scandal, there were longstanding criticisms of SEF's dual mandate. The agency was simultaneously responsible for border control and law enforcement while also managing administrative tasks like processing residence permits and visa applications. Critics argued that this combination created inherent conflicts, with enforcement priorities often overshadowing the service-oriented aspects of immigration management. The government concluded that separating these functions would lead to better outcomes for both security and immigrant integration.
What Is AIMA and How It Differs
AIMA, the Agência para a Integração, Migrações e Asilo (Agency for Integration, Migration and Asylum), was created as a purely civilian administrative body. Unlike SEF, AIMA has no police or enforcement powers. Its mandate focuses exclusively on the administrative side of immigration: processing residence permits, managing visa applications, overseeing integration programs, and handling asylum cases. This represents a fundamental philosophical shift from an enforcement-first approach to one centered on service delivery and immigrant integration.
The restructuring also included a reorganization of AIMA's internal competencies, with the stated goal of strengthening human and technological resources to improve productivity and quality control. In practice, this has meant new digital platforms, revised application procedures, and efforts to standardize processes across different regional offices. However, the transition has not been without growing pains, as the new agency absorbed SEF's massive backlog while simultaneously trying to implement new systems and train staff.
The New UNEF Border Unit
The enforcement and border control functions that previously belonged to SEF were transferred to a new entity called UNEF (Unidade Nacional de Estrangeiros e Fronteiras), which operates under the PSP (Polícia de Segurança Pública), Portugal's national police force. UNEF is responsible for border control at airports and seaports, enforcement of immigration law, deportation and removal proceedings, and investigation of immigration-related crimes.
This separation means that the people processing your residence permit application are now organizationally and functionally separate from those involved in border enforcement. For applicants, this distinction matters because AIMA staff approach cases from an administrative and integration perspective rather than a policing one. However, UNEF and AIMA must still coordinate on cases that involve both administrative and enforcement elements, and this interagency communication has occasionally created delays during the transition period.
Impact on Immigration Processing
The transition from SEF to AIMA has had mixed results for immigration processing. On the positive side, the agency has made measurable progress in clearing the inherited backlog, with government figures showing that 93 percent of pending cases have been resolved. The introduction of digital platforms and the strict complete-application requirement have the potential to streamline future processing. AIMA has also increased staffing, though the five percent increase achieved so far falls short of the 25 to 30 percent target acknowledged as necessary.
On the negative side, the transition itself created significant disruption. Staff had to be retrained, systems migrated, and new procedures established, all while dealing with a crushing volume of existing cases. Many applicants experienced longer wait times during the transition period as the new agency found its footing. Communication with AIMA remains a widespread complaint, with many applicants struggling to get updates on their cases through official channels. The staffing crisis, including overtime disputes and union actions, has further complicated matters.
What Applicants Need to Know
For current applicants, the most important practical change is that all interactions are now with AIMA rather than SEF. If you had a pending case with SEF, it was transferred to AIMA and should be accessible through AIMA's online portal. Your case number may have changed, so if you cannot find your application, contact AIMA directly or consult with a lawyer. All new applications must be submitted through AIMA's digital platforms, and the strict complete-application policy means every required document must be included at submission.
The institutional change also affects which entity you deal with for different matters. For administrative questions about your residence permit, visa status, or application progress, AIMA is your point of contact. For issues related to border control, deportation, or immigration enforcement, UNEF handles these matters through the PSP. Understanding this distinction can save you time and ensure you are directing your inquiries to the correct agency, which is particularly important given the communication challenges that persist with both entities.
