AIMA Replacing SEF: What the Immigration Transition Actually Changed
AIMA inherited SEF's residency mandate in late 2023 with a backlog measured in years. What actually changed, what is realistic now, what workarounds still hold.
8 min read
When SEF was dissolved in October 2023 and its civilian functions handed to a new agency, most foreigners assumed the change would be administrative. The change was constitutional in the smaller sense — a different ministry, a different culture, a different theory of what a residency dossier is for — and that is why the timelines looked the way they did through 2024 and 2025.
Quick Takeaways
- •AIMA inherited roughly 400,000 pending dossiers from SEF when the transition happened in late 2023
- •The agency operates under a different ministry and a different operating doctrine than its predecessor
- •Manifestação de interesse routes that worked under SEF were largely closed during 2024
- •Provisional documents during the wait carry uneven legal weight depending on the agency you present them to
- •The despachante and lawyer ecosystem has reorganized around AIMA's slower processing rhythm
The end of SEF was not a quiet rebrand. The Serviço de Estrangeiros e Fronteiras was a police force under the Ministry of Internal Administration with a foreign-resident-management mandate that had grown faster than its institutional capacity for a decade. By the early 2020s the backlog of pending residency dossiers had become a national embarrassment, and the political response was to dissolve the agency entirely and split its functions: border control to the police forces, civilian residency processing to a new entity called Agência para a Integração, Migrações e Asilo, AIMA, sitting under the Ministry of the Presidency.
What that change meant in practice took eighteen months to become legible. AIMA inherited the entire SEF backlog, every pending dossier and every appointment in the queue, but inherited it under a different operating culture and with a workforce being rebuilt from scratch. Foreigners who had submitted under SEF found their files paused, their appointments deferred, their cases routed through new offices that did not yet have the case histories of the people processing them. New arrivals after the transition entered a queue with no clear timeline. The agency has been catching up since, with real progress visible in 2025, but the lived reality for most pending applicants is still measured in years rather than months.
What the Transition Actually Was, Beyond the Press Release
The dissolution of SEF was approved by the Assembleia da República in late 2022 with an effective date originally set for early 2023, then pushed to October 2023 to allow time for AIMA to be operationally ready, then in practice became a rolling transition through the first half of 2024 as the new agency built out its regional offices and integrated the inherited case management systems. The legal basis for residency processing did not change. The visa categories, the income requirements, the document expectations, the renewal timelines all remained as they had been under SEF. What changed was the agency doing the processing and, with it, the institutional rhythm.
The new agency is, by design, less of a police force and more of an integration service. The doctrine in the founding legislation emphasizes facilitation of regular migration, integration support, and protection of asylum rights, with the enforcement mandate split off to other bodies. In practice the cultural shift has been slower than the doctrinal one — many of the case officers in the new agency are former SEF staff, the case management software is largely the inherited SEF system rebadged, and the appointment booking interface still has the SEF-era restrictions on slot availability that were the original cause of the backlog.
What is genuinely different is the political accountability. AIMA reports to a different ministry and is, in theory, more responsive to the executive's pressure to clear the backlog. The 2024 and 2025 budget cycles included specific funding for backlog processing, and the agency has been hiring case officers at a rate that was unthinkable under SEF. Whether that capacity translates into faster timelines for the next cohort of arrivals depends on whether the political pressure holds beyond the current parliament.
The Backlog Is Not One Queue but Several
The often-quoted figure of four hundred thousand pending dossiers at the moment of the transition is not a single queue. It is a layered set of queues, with very different processing speeds and very different odds of being resolved in any given month. The first layer is the renewal queue — foreigners whose initial residency cards expired before AIMA could process the renewal, who are technically legal under the deemed-renewal provisions but whose physical card is overdue. This queue has moved fastest because the underlying dossier already exists and the processing is incremental. Most renewal applicants from 2022 and 2023 had cards in hand by the end of 2025.
The second layer is the manifestação de interesse queue — the regularization route that allowed foreigners already physically present in Portugal to begin a residency process even without a prior visa. This route was the political flashpoint of the SEF era and was substantially closed by the AIMA-era government in mid-2024, with most pending manifestação dossiers being either processed slowly or returned for the applicant to leave and restart through a consular visa. This queue is where the most uncertainty remains, and where individual outcomes depend heavily on the specific office and the specific case.
The third layer is the consular visa queue — first-time arrivals through D7, D8, Golden Visa, or work-visa routes, who arrive with a visa already in their passport and need AIMA only to complete the residency card issuance. This queue has been the most predictable, with most 2025 arrivals receiving cards within six to twelve months of their initial AIMA appointment. The despachante community has reoriented around this route as the most reliable path for new clients, which is part of why D7 and D8 advice has become so dominant in expat conversation since the transition.

What the Provisional Documents Actually Buy You During the Wait
Most foreigners caught in the AIMA timeline live for some period with provisional documentation rather than the actual residency card. The shape of that documentation depends on where in the process the wait is happening. Pre-appointment, the applicant typically holds the visa stamped in their passport and a manifestação de interesse acknowledgement or appointment confirmation. Post-appointment but pre-card, the applicant holds a comprovativo of the submitted application and, in many cases, the appointment record. Renewal-pending applicants hold the expired card plus the renewal request acknowledgement and the deemed-renewal legal protection.
The legal weight of these documents is technically equivalent to a valid card for most purposes — the resident is regular, can work, can access the SNS, can travel within Schengen on the basis of the underlying visa or the provisional status. The practical weight varies wildly. Banks accept the comprovativo from major networks but not always from the digital alternatives. Landlords accept it from established tenants but rarely from new applicants competing for scarce rental supply. Schools accept it for enrollment but sometimes ask for the card before the school year starts. The Schengen border crossing has been the consistently uneven point — most border officers in major airports are now familiar with the AIMA documents but smaller crossings, especially overland, still occasionally produce trouble.
The unavoidable workaround for many applicants is to keep all of the provisional paperwork in physical form, with multiple printed copies and the original visa pages photographed, because the digital comprovativo from the AIMA portal sometimes fails to load when it is needed. The despachante community advises clients to carry a folder rather than a phone for any official interaction, and that advice has held through every iteration of the AIMA portal so far.
Booking an Appointment, in the Reality of 2026
The AIMA appointment system is the part of the agency that most resembles its SEF predecessor and that the agency has been least able to reform. Slots are released in waves on the AIMA portal, the wave timing is not announced in advance, and the slots disappear within minutes of being released because the demand vastly exceeds the supply. The community has responded with a small ecosystem of bots and watchers that monitor the portal continuously and notify subscribers the moment new slots appear, and the ethical status of these tools has become a recurring conversation in the despachante community.
What has worked more reliably than the public portal for many applicants is the prioritization channels that AIMA has established for specific categories — Golden Visa applicants, certain employer-sponsored work-visa categories, family reunification cases, and applicants under specific humanitarian protections. These channels do not bypass the queue entirely but they assign appointments through different administrative processes that have less of the wave-release dynamic. Most applicants do not qualify for these channels, but those who do should use them rather than competing in the open booking system.
The despachante value-add at this stage is genuinely significant. A good despachante is monitoring the portal continuously, has relationships with specific AIMA offices that occasionally produce out-of-band slots, and knows which days and times the new wave releases tend to happen. The cost of that service has risen sharply since the transition, and the quality is uneven. The recommendation from most experienced expats is to ask for references from people who completed the process in the past twelve months, not from older arrivals whose advice predates the AIMA era.
What to Actually Do Now, in Practice
If you are pre-arrival, the strongest recommendation is to enter Portugal through a consular visa rather than through any kind of in-country regularization route. The manifestação channel is largely closed, the political wind is against reopening it, and arriving with a visa in your passport puts you in the most predictable of the AIMA queues. The downside is that consular visa processing in many countries — particularly the United States, the United Kingdom, and Brazil — has its own backlog that can run six to twelve months, and the consular visa requires the income, insurance, and accommodation documentation to be assembled before submission rather than after.
If you are mid-process and waiting for the card, the strongest recommendation is to keep the provisional paperwork organized and to renew any underlying visa stamp before it expires, even if the renewal is purely procedural. The AIMA timeline is long enough that the visa expiry can become a separate problem that compounds the residency wait. Keep an eye on the caixa postal eletrónica inside the Portal das Finanças, because some AIMA correspondence now flows through that channel rather than through physical post or the AIMA portal directly.
If you are renewing a card that has already expired or is about to, do not panic about the gap. The deemed-renewal provisions cover the legal status during the wait, and the practical workarounds for the documentary edges are well-established. The most common mistake at the renewal stage is to delay the application out of confusion about the new portal, which then compounds into a longer wait when the dossier eventually does enter the queue.
What This All Adds Up To
AIMA is a real improvement on SEF in design, an uneven improvement in delivery, and a genuine source of frustration for the cohort of foreigners who happened to be in process during the transition years. The trajectory is positive — the backlog is shrinking, the new arrivals through consular visas are seeing more predictable timelines, the agency is staffing up. The trajectory is also slow, and slower than the political rhetoric of any given month suggests.
The honest version is that anyone moving to Portugal in 2026 should plan for an eighteen-month residency processing window from arrival to physical card, should organize their life so that the provisional documents are workable for that window, and should treat the despachante decision as a meaningful one rather than as a small convenience. None of this is a reason not to come. It is a reason to come with realistic expectations.
