What Contagem do Tempo Is
Contagem do Tempo, which translates literally as "time count," is an official AIMA-issued document that certifies two things: the start date AIMA recognises as the beginning of your legal residence in Portugal, and the total accumulated period of legal residence on record up to the date of issuance. It is the document the Conservatória dos Registos Centrais relies on when reviewing a citizenship application to determine whether the residency requirement has been met. Without it, citizenship reviewers must reconstruct the residence period from the underlying visa and permit history themselves, which slows processing and increases the risk of an erroneous denial for insufficient residency time.
The certificate is not new and is not unique to citizenship preparation, but its strategic value has spiked in 2026. With the Nationality Law amendment moving the citizenship clock from a 5-year to a 10-year requirement and changing how residency time is calculated, applicants who are close to the five-year mark have a strong interest in confirming exactly what AIMA has on file before filing. As one expat shared in a recent r/PortugalExpats thread: "I and my immigration advisor were not sure if I was able to submit early or wait until the date on my residence card... turns out in my case they have my residence date beginning at the start of my D7 residence visa." Discovering that earlier rather than later is the entire point of requesting the certificate.
Why the Visa-Issuance Date Matters More Than the Arrival Date
For citizenship purposes, Portuguese law counts legal residence from the date the residence visa or residence permit was issued — not from the date the holder physically arrived in Portugal. This distinction matters because Portuguese consulates abroad routinely issue residence visas weeks or months before the holder actually relocates. A D7 visa issued on March 15 of a given year for an applicant who flew to Lisbon on July 1 has the residence clock starting on March 15, not July 1. For someone close to the five-year mark, that gap can mean the difference between being eligible for citizenship today versus being eligible four months from now.
The same logic applies to D8 digital nomad visas, D2 entrepreneur visas, and Golden Visa pathways. In every case, the date on the visa stamp issued by the consulate is the reference date for AIMA's residence calculation. The first physical residence card you collect at AIMA after biometrics is a different document with a different issue date, but the residence period predates it. Applicants who assume their residence period started when they collected the card consistently underestimate their accumulated time. The Contagem do Tempo certificate is the way to confirm which date AIMA has applied to your case before you commit to a filing strategy.
Which AIMA Offices Are Issuing the Certificate
Practice across AIMA's regional offices has been inconsistent. The offices most reliably issuing Contagem do Tempo certificates on request as of April 2026 are Alverca and Setúbal, both of which have been processing requests on a walk-in basis without an appointment. Reports from immigration lawyers indicate that Lisbon-area offices vary by individual office and by the staff member receiving the request. Some Lisbon offices will issue the certificate on the spot; others will refuse and refer the applicant to a different mechanism. If you live in the Lisbon metropolitan area, travelling to Alverca or Setúbal is often the fastest path to obtaining the document.
Outside the Lisbon area, the Porto office has been issuing certificates on appointment but not on a walk-in basis. The Coimbra and Faro offices have been issuing them with longer turnaround times, often by post rather than in person. If your situation is time-sensitive — for example, if you are trying to file a citizenship application before the Nationality Law amendment is promulgated — prioritise an office that is currently issuing the certificate on the day of the visit, even if it requires a one-off trip. The cost of a day spent travelling to Alverca or Setúbal is typically much smaller than the cost of waiting four to six weeks for a postal certificate from a regional office.
Documents to Bring and How to Request It
Bring your current residence card, your passport, your NIF, and your NISS. If your initial residence visa is in a previous passport, bring that passport as well. If the visa stamp itself is no longer accessible (for example, the original passport is in a foreign government's possession during a renewal), bring whatever consular paperwork you have showing the visa issue date. The certificate request itself is processed against AIMA's internal records, but having the supporting documents on hand can resolve any data discrepancies on the spot rather than triggering a follow-up appointment.
The request itself is made on a standard AIMA form available at the office. Some applicants have reported finding the form online through immigration lawyers or expat community resources, but the version available at the office is the version AIMA will accept. Fill it in legibly with your full name as it appears on your passport, your residence permit number, and your NIF. Specify that you are requesting "Contagem do Tempo de residência legal em Portugal" for the purpose of "instrução do processo de aquisição de nacionalidade." Submit the form and your supporting documents to the AIMA staff member at the front desk. In offices where same-day issuance is the practice, you should receive the certificate before leaving. In offices using postal issuance, you will receive a receipt and a follow-up notification when the certificate is ready.
When to File Your Citizenship Application After Receiving It
Once you have the certificate in hand and it confirms that your residence period meets or exceeds the current five-year requirement, file your citizenship application immediately. Until the Nationality Law amendment is promulgated in the Diário da República, the 5-year rule remains in force. Filings accepted under the current regime are processed under the rules in effect at the date of filing, not the date of the Conservatória's decision. This procedural protection is the single most important reason to file as early as possible if you are eligible.
If the certificate reveals that your residence period falls short of five years by a small margin, your strategic options narrow but are not eliminated. You may still wait until the date arrives and file before promulgation, accepting some risk that the law could be promulgated in the interim. You may decide to file as a precautionary submission and accept that an early-filing rejection will be appealable. Or you may simply wait and plan under the new 10-year regime, using the Contagem do Tempo certificate as the foundation document for that long-term plan. A consultation with an immigration lawyer is worthwhile before any of these decisions, because the choice depends on facts specific to your case. The renew-TRC-versus-citizenship strategic decision guide goes into the trade-offs in more detail.
How the New Nationality Law Changes the Calculation
If the Nationality Law amendment is promulgated as passed on April 1, 2026, the residency clock will be counted from the date your first residence card was issued by AIMA, not from the date your residence visa was issued by the consulate. This is a meaningful change. For most applicants, the residence card is issued several weeks to several months after the residence visa, depending on AIMA's processing time at the date of arrival. Applicants who currently benefit from a visa-issuance counting date would lose that benefit under the new regime, and would instead start their clock from the residence card issuance.
For applicants planning under the new 10-year regime, the Contagem do Tempo certificate remains valuable but for a different reason. It establishes a clear reference point for the start date AIMA has on record, which can be cross-referenced against the date of your first residence card to estimate when your 10-year clock will reach maturity. It also serves as a baseline document if any future amendment changes the rules again — which has been a recurring pattern in Portuguese nationality law over the past decade. For long-term planning, having an official AIMA-issued document fixing the dates is more useful than relying on memory or on photocopies of older visa stamps. Use the residency time calculation guide to model your eligibility date under both the old and new rules.
Frequently Asked Questions
What is a Contagem do Tempo certificate from AIMA?
Contagem do Tempo is an official AIMA-issued document that certifies the start date and total accumulated period of your legal residence in Portugal. It is the document the Conservatória dos Registos Centrais will rely on when assessing whether you meet the residency requirement for citizenship. Requesting it before filing your application lets you confirm exactly which date AIMA has on record.
Does AIMA count my residence from the date my visa was issued or the date I arrived?
AIMA generally counts legal residence from the date the residence visa was issued by the Portuguese consulate, not from the date you physically arrived in Portugal. For applicants whose visa was issued weeks or months before they actually moved, this can shift the citizenship eligibility date forward. The Contagem do Tempo certificate confirms the specific date AIMA is using for your individual case.
Which AIMA offices issue the Contagem do Tempo certificate?
AIMA offices in Alverca and Setúbal have been the most consistent in issuing Contagem do Tempo certificates on a walk-in basis. Other offices may issue it on request, but practice has been inconsistent across regions. If you are close to the five-year mark, prioritise the offices known to be currently issuing it, and bring your request form pre-filled.
Will the certificate still be useful under the new 10-year nationality law?
Yes, even more so. Under the new law, residency for citizenship is counted from the date the first residence card is issued by AIMA. The Contagem do Tempo certificate is the official AIMA document confirming that date. For long-term planning under the 10-year regime, having the certificate establishes a fixed reference point that you can rely on through future renewals and law changes.
Should I file my citizenship application before or after requesting Contagem do Tempo?
Request the certificate first, ideally several weeks before you intend to file. The certificate confirms whether your eligibility date has been reached. Filing prematurely without verifying the start date AIMA has on record is one of the most common reasons citizenship applications are rejected for insufficient residency time. The certificate also becomes a supporting document in the citizenship file, which can shorten Conservatória processing time.
