Researcher Residence in Portugal
The Article 91-B route for researchers admitted to an officially recognised research centre — the lightest document file of any residence route, with one hard catch on family.
Last verified: July 2026
This guide covers the researcher residence route: a non-EU/EEA/Swiss national admitted to carry out research at an officially recognised research centre in Portugal enters on a residence visa under Article 62 of the immigration law (Lei n.º 23/2007), then applies to AIMA for a residence permit under Article 91-B. The route exists because Portugal transposed EU Directive 2016/801 through Lei n.º 102/2017.
It does not cover degree students, including PhD candidates enrolled and funded as students (Student Residence); teaching or highly qualified work at a university (Highly Qualified Activity — read the callout below before assuming that isn't you); ordinary employment (Work Residence); founding a company (Entrepreneur Visa (D2)); remote work for a foreign employer (Digital Nomad Visa (D8)); passive income (Passive Income (D7)); CPLP nationals (CPLP Residence); or joining a relative (Family Reunification). If you're unsure, start with Which Immigration Route Is Right for You?.
At a glance
- Route: Article 62 residence visa for research → travel → AIMA residence permit under Article 91-B
- Who uses it: postdocs, research fellows, principal investigators and contracted scientific staff at universities, associate laboratories and research centres — provided the centre is officially recognised
- The money test: for a researcher at a recognised centre, there isn't one. Article 91-B(2) disapplies the means-of-subsistence requirement, and the Ministry of Foreign Affairs waives it at the visa stage too.
- Visa fee: €0. A national visa normally costs €110 (Portaria n.º 91/2025/1), but highly qualified research activity is expressly exempt — as are holders of Portuguese-State scholarships.
- AIMA decision period: 60 days for a researcher at a recognised host (Article 96(5)). The general rule is 90.
- Permit validity: 2 years, renewable for equal periods — or the duration of the hosting agreement, if shorter.
- Lawyer required? No. But if you have a spouse, read the family section twice — there a lawyer may genuinely earn their fee.
- Family? Yes, but not quickly. Researchers are not exempt from the two-year sponsor waiting period. This is the most important thing in this guide.
- Counts toward PR / citizenship? Yes, at full weight. Permanent residence at 5 years; citizenship at 7 or 10 years depending on nationality.
- Main authorities: your host institution; the Portuguese consulate or visa centre; AIMA after arrival.
Is this route for you?
Use this route if all of these are true:
- You are not a citizen of an EU Member State, the EEA or Switzerland.
- A Portuguese research centre, associate laboratory or university research unit has admitted you to carry out research.
- That centre is officially recognised for hosting third-country researchers. This is the pivot of the entire route.
- Research is your primary activity — not study for a degree, and not ordinary commercial employment.
Use another guide if you are enrolled and funded as a student, including most PhD candidates (Student Residence); if your post is really a teaching post or a highly qualified role, in which case Highly Qualified Activity may be a materially better route; or if you're joining a Portuguese employer in an ordinary commercial job (Work Residence).
One-minute summary
Get admitted to a recognised centre. Get the centre to confirm in writing that it is recognised. Apply for the Article 62 visa at the consulate responsible for where you legally live — it is free. Travel within the visa's four-month, two-entry window. Attend the AIMA appointment. Because you are a researcher at a recognised host, AIMA must decide within 60 days, and it may not require proof of means, proof of accommodation, or Social Security registration.
That is the whole route. Everything below is how to earn it, or how not to lose it.
The pivot: admission to a recognised centre — not the hosting agreement
The most repeated error about this route — in blogs, in law-firm pages, and in the previous version of this guide — is that the convenção de acolhimento (hosting agreement) is mandatory, and that nothing proceeds without it. It is not.
*Official Requirement.* The law admits four ways to evidence the research relationship, and any one of them suffices:
- An employment contract with the host institution.
- A service contract (contrato de prestação de serviços).
- A research grant or fellowship (bolsa de investigação).
- A convenção de acolhimento.
A postdoc on an FCT fellowship does not need a hosting agreement on top of the fellowship. A researcher on a fixed-term contract does not need one either.
*Legal Interpretation.* What actually unlocks this route — the fast decision, the free visa, and above all the exemptions — is admission to an officially recognised research centre. The instrument is *evidence* of that admission; it is not the source of the rights. If an administrator tells you your file cannot proceed without a convenção when you already hold a signed research contract, they are describing a habit, not the law.
The exemptions — why the researcher file is the lightest in Portuguese immigration
*Official Requirement.* Article 91-B(2) disapplies Article 77(1)(d), (e) and (f) for a researcher admitted to a recognised centre. At the AIMA stage you do not have to prove:
- Means of subsistence. No bank statements, no minimum-wage multiple, no term of responsibility.
- Accommodation. No landlord declaration, no land-registry certificate, no sworn declaration of the legal basis on which you occupy your home.
- Registration with Social Security. The NISS requirement — which traps people in a genuine catch-22 on other routes — does not apply at the initial grant.
*Official Requirement.* At the visa stage the Ministry of Foreign Affairs goes further, waiving the health insurance, the travel insurance, the contract and the means of subsistence a normal residence-visa applicant must produce. With the fee exemption on top, this is the closest thing Portuguese immigration has to a document-free application.
Compare: a D7 applicant must show twelve months of income available in a Portuguese bank account; a D8 applicant four times the minimum wage; a work-residence applicant a contract, a means file, an accommodation file and a NISS. A researcher at a recognised centre produces none of it.
AIMA's own page contradicts itself — carry the proof. AIMA's document list for this route sets out means of subsistence and the accommodation declaration under its general documents heading, then, in the notes below, exempts recognised-centre researchers from exactly those items. Both statements sit on the same page. In practice, counter staff may ask for documents the law says you don't owe. Don't argue from memory: carry the institution's written confirmation of its recognised status to the appointment, on letterhead, and put it on top of the file. It is the document that makes the other documents unnecessary.
The recognised-centre problem: there is no register
*Practical Advice.* The law provides that the list of recognised research centres is kept at AIMA. In practice no such register is published anywhere — not by AIMA, not by FCT, not in the Diário da República. We looked. We won't pretend otherwise.
So do not plan to "check the register". There isn't one. Instead, ask your host's research-support or international office to confirm, in writing and on letterhead, that the centre is officially recognised for hosting third-country researchers under Article 91-B, in those words, referencing the basis of that recognition. Get it before you resign a post, book a flight, or sign a lease.
That single sheet of paper is worth more than any other document in your file: it triggers the 60-day decision period, the fee exemption and the three exemptions above. Without it you are, on paper, an ordinary applicant with an unusually thin file — exactly the profile that gets refused. If your host cannot or will not produce it, treat that as a serious signal.
The family reunification correction — read this before anything else
Researchers are not exempt from the two-year sponsor waiting period. You will read the opposite in many places. It is wrong.
*Official Requirement.* Under Article 98(1), as amended by Lei n.º 61/2025 (in force 23 October 2025), a sponsor must hold a residence permit that has been valid for at least two years before family may be reunified. Article 98(3)(c) exempts only the families of holders under Article 90 (highly qualified, teaching, cultural), Article 90-A (investment/ARI) and Article 121-A (EU Blue Card).
Article 91-B is not on that list. It is simply absent — as are Article 89 (entrepreneurs), Article 91 (students) and the CPLP permit. The ordinary two-year rule therefore applies to a researcher's family.
*Legal Interpretation.* This sits in real tension with Article 26(3) of Directive 2016/801, which provides that a Member State may not apply a waiting period to researchers' families — the very Directive Portugal transposed through Lei n.º 102/2017. But no Portuguese provision and no published ruling resolves the conflict, and Lei 61/2025, the most recent word from Parliament, wrote the exemption list without researchers in it. We will not tell you that a Directive you cannot enforce at an AIMA counter will get your spouse a permit.
Honestly, then:
- Plan for two years. Be pleasantly surprised if a lawyer finds a way through.
- Article 91-B does refer to family reunification, so a researcher's family is not excluded from the regime — the fight is over timing, not the right.
- A discretionary waiver exists (Article 98(4)): the period may be waived or reduced in reasoned exceptional cases by ministerial order. It is discretionary. It is not a plan.
- Minor children and dependent incapable persons are exempt from the waiting period under Article 98(3)(a) whatever permit the sponsor holds. So in practice this is mostly a spouse problem.
- The Directive point is genuinely arguable — more than can be said for most immigration grievances. Arguing it is a lawyer's job.
The single most consequential decision in your application. If your post involves teaching, or is a highly qualified role at a higher-education institution, you may qualify under Article 90 instead of Article 91-B. Article 90 is on the family-exemption list. Same person, same laboratory, same salary — different article, and your spouse either waits two years or does not. Ask your host what your contract actually is, then read Highly Qualified Activity. The exemption attaches to the permit article, not to how impressive the job is. Note too that Article 98(3)(c) disapplies only the two-year rule in n.º 1 — the separate 15-month rule in n.º 2 is not expressly disapplied, so don't assume Article 90 means "no wait at all" for a spouse without a lawyer's read.
The complete process
Step 1 — Confirm the recognised status, in writing
Before anything else. Nothing in this guide works without it.
Step 2 — Establish which instrument you hold
Employment contract, service contract, research grant, or convenção. Any one of the four. If your host issues a teaching or highly qualified contract instead, stop and re-read the callout above.
Step 3 — Get a NIF
A tax representative can obtain one while you are still abroad. You are exempt from NISS at the initial grant; the NIF is worth having regardless.
Step 4 — Assemble the visa file
*Official Requirement.* For an Article 62 residence visa for research, expect the consulate to require the national-visa application form; a valid passport and photographs; evidence of the research relationship (contract, service contract, grant or convenção); the host's confirmation of recognised status; a criminal-record certificate; and authorisation for the Portuguese authorities to consult the Portuguese criminal record.
*Practical Advice.* The means, contract and insurance items on every other national-visa checklist are waived for this route by the Ministry. Consular practice varies, and an officer working from a generic checklist may ask anyway. Bring the recognition letter and be polite. Consulate practice is not law — but a consulate can still delay you.
Step 5 — Submit, and pay nothing
Submit at the consulate or visa centre responsible for where you legally reside — not necessarily your country of nationality. The visa is free. A private visa centre may still charge its own service fee; that is the centre's charge, not the State's.
Step 6 — Check the visa, then travel
The residence visa is normally valid for two entries and four months. Check the name, passport number, dates and entries. The AIMA appointment is normally created when the Ministry issues the visa, reachable through the link printed on the visa sticker. Open it and save it before you fly.
Step 7 — The AIMA appointment
Bring originals, the recognition letter on top, the instrument, the passport and the visa.
*Official Requirement.* AIMA must decide within 60 days for a researcher at a recognised host (Article 96(5)), against a general rule of 90. It is a statutory service period, not a promise — but it is worth knowing you have it.
*Observed Practice.* Expect to be asked for the means and accommodation documents the law exempts you from. Answer with the recognition letter and Article 91-B(2).
Documents
The recognition letter. Not a named legal requirement, and the most important document you will carry. On letterhead, from the host, stating that the centre is officially recognised for hosting third-country researchers under Article 91-B. It exists because there is no public register anyone can check. Common mistake: accepting a verbal assurance.
The research instrument. One of: employment contract, service contract, research grant, convenção. It should identify you, the institution, the project, the duration and the funding. Common mistake: waiting for a convenção you don't need because you already hold a contract or a grant.
Passport. Valid well beyond the permit you're asking for. Common mistake: renewing it mid-process, which orphans the visa.
Criminal-record certificate. *Official Requirement.* From your country of nationality OR a country where you have lived more than one year — an or, not an and, and guides routinely get this wrong. Under-16s are exempt. Neither AIMA nor the Ministry publishes any validity window; the commonly-quoted "90 days" is consular and visa-centre practice, not a published rule. *Practical Advice.* Get one issued within about three months of filing — but not so early that a consulate treats it as stale.
Authentication and translation. A document from a Hague Convention country needs an apostille; otherwise consular legalisation. EU-issued documents need no formalisation at all (Regulation (EU) 2016/1191). And *Official Requirement.* documents in English, French or Spanish need no translation (Article 49(8), Código do Registo Civil) — a large, under-reported saving covering most researchers' academic and civil papers. Anything else needs a certified translation.
Academic qualifications. Your host has already assessed them; the authorities primarily assess whether you meet the route's legal conditions. Bring them anyway, apostilled where issued abroad. Academic recognition and professional registration (relevant if your research is clinical) are separate processes from immigration.
Health insurance. Waived at the visa stage for this route. Do not rely on the "€30,000 minimum cover" figure quoted everywhere — that is the Schengen short-stay minimum, and has nothing to do with a national residence visa.
Accommodation. You are exempt at the AIMA stage. Worth knowing anyway: AIMA does not require a registered 12-month lease. Its lists ask for a sworn declaration of your address and the legal basis on which you occupy it, plus a land-registry certificate (if you own) or a declaration from the landlord or hosting entity. There is no "Modelo 2" in immigration — that is the landlord's stamp-duty form for Finanças.
Fees
*Official Requirement.* The visa is free. A national visa normally costs €110 under Portaria n.º 91/2025/1, in force since 11 March 2025, but highly qualified research activity is expressly exempt, as are holders of Portuguese-State scholarships. Several gov.pt service pages still print an obsolete €90; the Ministry of Foreign Affairs is who charges the fee, and its table governs.
AIMA's charges are a separate table, re-indexed on 1 March 2026. For a first temporary permit: reception and analysis €133.00, the title itself €114.30 — about €247 in total, reduced by 25% through the digital channel (roughly €186). There is no separate card fee.
*Practical Advice.* That table is re-indexed every March. Check the current AIMA table immediately before your appointment rather than trusting any total, including this one.
How long does it take?
*Official Requirement.* AIMA has 60 days to decide a researcher's permit at a recognised host (Article 96(5)). That is a statutory service period, not an average.
*Observed Practice.* Consular decision periods for residence visas run to an official 60 days; real timing varies with the post, the season and whether extra documents are requested. We publish no average, because there is no dated, documented sample we would stand behind. Anyone quoting a confident number is guessing.
Intra-EU mobility — the researcher's real superpower
*Official Requirement.* Short-term (Article 91-C): if you hold a researcher permit from another EU Member State, you may carry out research at a recognised Portuguese host for up to 180 days in any 360, on that permit, "com dispensa de quaisquer outras formalidades" — with no other formalities. Your family may accompany you.
*Official Requirement.* Long-term: beyond 180 days, apply to AIMA within 30 days; AIMA decides within 90. The title issued reads "mobilidade investigador".
This is genuinely unusual in Portuguese immigration, and under-used. If you're splitting a project across two European labs, check it before assuming you need a fresh visa.
After the research ends
*Official Requirement.* Article 122(1)(p): a researcher who has finished may obtain a residence permit with the residence visa waived for up to one year, to look for work or to create a company.
It is one year, not nine months. Nine months is the Directive's floor; Portugal legislated above it. The "9 months" figure is repeated in a great many places — including the previous version of this guide — and it is wrong in the direction that costs you three months of runway. You do not need to leave Portugal to use it. Plan it before your permit nears expiry.
Permanent residence and citizenship
*Official Requirement.* Time on a researcher permit counts as legal residence at full weight. Permanent residence still requires 5 years (Article 80) — Lei n.º 61/2025 did not change that. Don't let the nationality changes below contaminate it; they are different clocks, and readers conflate them constantly.
The half-weight rule that circulates in student guides applies only to study, unpaid training and volunteering, and only for the separate EU long-term-resident status. Research is not halved.
*Official Requirement.* Citizenship by naturalisation now requires 7 years of legal residence for nationals of Portuguese-language countries and citizens of EU Member States, and 10 years for everyone else — Lei Orgânica n.º 1/2026, in force 19 May 2026. Research residence counts with no reduction.
The transitional rule protects fewer people than you think. Only procedures already filed on 19 May 2026 keep the old five-year rule. Simply *having* five years of residence on that date protects nobody. See Becoming a Portuguese Citizen.
Tax: IFICI is built for exactly this profile
The IFICI regime (Article 58-A of the EBF), which replaced the closed NHR, is aimed squarely at scientific research and innovation: a 20% flat IRS rate on qualifying Portuguese employment and self-employment income, and an exemption on most foreign-source income — but not on pensions. It is mutually exclusive with NHR. Tax residence is triggered by more than 183 days in any 12-month period, or, with fewer days, by the habitual-abode test.
*Practical Advice.* Researchers are among the most likely to qualify and the most likely to miss the registration deadline, which is not retroactive. This is tax advice, not immigration. Get it from a qualified professional in your first months, not your second year.
Are you still legal — and can you travel?
The residence visa gives you two entries and four months to enter and complete the permit procedure. Count the exact dates printed on it.
*Official Requirement.* AIMA states it in terms: "o recibo comprovativo do pedido de concessão de autorização de residência não é um documento de viagem" — the receipt proving you applied for a residence permit is not a travel document. A pending appointment is not one either. Do not book a conference abroad on the strength of a receipt.
Once you hold the permit, movement in the Schengen Area follows the Schengen Borders Code. We are not going to tell you a residence permit is a 90-days-in-180 travel pass: no Portuguese official page states it in those terms, and one Portuguese consulate states flatly that a national visa does *not* permit entry to other Schengen states. Check your specific position before booking.
AIMA appointments are free. Never pay for a slot. Anyone selling a "guaranteed AIMA appointment" is running a scam. Researchers face a second, more specialised version: predatory or unrecognised "institutes" selling hosting agreements or research affiliations for a fee. A hosting agreement from a body that is not officially recognised is worthless for immigration purposes, and no amount of paperwork fixes it. Verify the recognised status in writing before you pay anyone anything, resign a post, or move a family.
If something goes wrong
- Your host cannot confirm its recognised status. Stop. Escalate in writing to the research-support or international office. Do not proceed on a verbal assurance.
- The convenção is delayed. Check whether you need it at all. A contract, service contract or grant may already be an admissible instrument.
- AIMA demands means or accommodation documents. Present the recognition letter and Article 91-B(2). If the counter insists, submit under protest, keep proof of what you submitted, and get advice — but don't lose the appointment over the argument.
- Funding is withdrawn or the project ends early. Your permit rests on the research activity. Look at Article 122(1)(p) — the one-year post-research permit — and get advice promptly rather than waiting for a renewal to fail.
- The application is refused. Read the written grounds and the challenge deadline, which can be short. A refusal because the institution is not recognised, or because the activity is not accepted as research, is substantive: the case must be rebuilt, not patched.
Anything adversarial — a refusal you want to overturn, a disputed assessment of your host's status, a file stuck past the 60-day deadline, or an argument that Directive 2016/801 entitles your spouse to come now — runs on filing windows and formal procedure. That is a lawyer's job.
Frequently asked questions
Do I need a convenção de acolhimento?
Not necessarily. It is one of four admissible instruments, alongside an employment contract, a service contract and a research grant. Any one of them evidences the research relationship.
So what actually matters?
Admission to an officially recognised research centre. That is what triggers the exemptions, the 60-day decision and the free visa. The instrument is evidence of the admission, not the source of the rights.
How do I check whether my institution is recognised?
You can't — there is no published register. The law says the list is kept at AIMA; nothing is publicly available. Get the institution to confirm its recognised status in writing, on letterhead.
Do I have to prove I have money?
No. Article 91-B(2) exempts a researcher at a recognised centre from proving means and accommodation, and from Social Security registration. The Ministry also waives means, the contract and both insurances at the visa stage.
Then why does AIMA's page list means and accommodation?
Because the page contradicts itself: it lists them under general documents, then exempts you in the notes. Carry the recognition letter and cite Article 91-B(2). Expect to be asked anyway.
How much is the visa?
Free. Highly qualified research activity is expressly exempt from the €110 national-visa fee, as are Portuguese-State scholarship holders. A private visa centre may still charge its own service fee.
How long is the permit valid?
2 years, renewable for equal periods — or the length of the hosting agreement, if shorter. The "1 year" figure you may see belongs to a narrow mobility-programme case.
How long does AIMA take to decide?
60 days for a researcher at a recognised host (Article 96(5)), against a general rule of 90. It is a service period, not a promise.
Can my family come with me straight away?
No. Researchers are not on the Article 98(3)(c) exemption list — only Articles 90, 90-A and 121-A are. The ordinary two-year sponsor waiting period applies. Minor children are exempt under a different provision, so in practice this is mostly a spouse problem.
But the EU Directive says researchers' families don't wait!
Article 26(3) of Directive 2016/801 does say that. Portugal's statute, as amended by Lei n.º 61/2025, does not reflect it, and no Portuguese provision or ruling resolves the conflict. We won't promise an exemption you cannot rely on at an AIMA counter. It is genuinely arguable — and arguing it is a lawyer's job.
Is there any way around the two-year wait?
Three, none guaranteed. Minor children are exempt regardless of the sponsor's article. A discretionary ministerial waiver exists (Article 98(4)). And — most usefully — if your post is teaching or highly qualified work at a higher-education institution, you may qualify under Article 90, which is on the exemption list.
Is Article 90 better than Article 91-B, then?
For a researcher with a spouse, possibly — it may be the most consequential choice in the application. But Article 91-B carries the exemptions from means, accommodation and NISS, the free visa and the 60-day decision; Article 90 does not. It is a real trade-off. Read Highly Qualified Activity and take advice.
I'm a PhD candidate. Am I a student or a researcher?
It depends on your instrument. Enrolled and funded as a student → the student route. Contracted, employed or fellowship-funded to carry out research → this route. The document lists differ, and the student route carries no exemptions like these.
Can I teach as well?
It depends on what your contract or convenção says — there is no general permission and no general prohibition. If teaching is a substantial part of the post, see the Article 90 callout above.
I already hold a researcher permit from another EU country. Do I start over?
Probably not. Short-term mobility lets you research at a recognised Portuguese host for up to 180 days in any 360, with no other formalities, on your existing permit — family included. Beyond 180 days, apply to AIMA within 30 days; the decision comes within 90.
What happens when the research ends?
Article 122(1)(p) gives you a residence permit, with the visa waived, for up to one year, to look for work or create a company. One year — not the nine months widely repeated online, which is only the Directive's minimum.
Does my research time count toward permanent residence and citizenship?
Yes, at full weight for both. Permanent residence is still 5 years (Article 80). Citizenship is now 7 years for nationals of Portuguese-language countries and EU Member States, 10 years for everyone else (Lei Orgânica n.º 1/2026). The half-weight rule applies only to study, unpaid training and volunteering, and only for the separate EU long-term-resident status.
Do my documents need translating?
If they are in English, French or Spanish — no. Anything else needs a certified translation. EU-issued documents need no apostille either.
Do I need €30,000 of health insurance?
No. That is the Schengen short-stay minimum and does not apply to a national residence visa. For this route the Ministry waives the insurance requirements entirely.
Is a lawyer compulsory?
No. Consider one for a refusal, for a disputed assessment of your host's status, and — seriously — for the family-timing question if you have a spouse and the Article 90 alternative might be open to you.
Before you submit: final checklist
- Recognised status of the host confirmed in writing, on letterhead.
- The research instrument identified and signed — contract, service contract, grant or convenção. You need one, not all four.
- The Article 90 question asked and answered, if you have a family.
- Correct consulate or visa centre identified — the one responsible for where you legally reside.
- Passport valid well beyond the permit period.
- Criminal record from the correct country (nationality or >1 year of residence — not both), recent, apostilled or legalised where needed.
- Translations only where actually needed (not for EN/FR/ES).
- NIF obtained.
- Visa checked on issuance: name, passport number, two entries, four months.
- AIMA appointment link opened and saved.
- Recognition letter on top of the file. Originals packed.
Portugeasy checks your specific documents against the current AIMA requirements before your appointment and flags what would be rejected. On this route the risk runs in an unusual direction: the danger is not that you bring too little, but that you cannot prove you are entitled to bring less.

Changelog
- 13 Jul 2026 — Published as a live chapter. Full factual rebuild. Legal basis corrected to Art. 91.º-B (Lei n.º 102/2017, transposing Directive 2016/801). Removed the claim that the convenção de acolhimento is mandatory — it is one of four admissible instruments — and rebuilt the guide around the real pivot: admission to an officially recognised centre. Added the recognised-centre exemptions (means, accommodation, Social Security, plus the MNE visa-stage waivers), omitted entirely by the previous version. Corrected the visa fee to €0, permit validity to 2 years, the AIMA decision period to 60 days, and the post-research stay to one year (not nine months). Corrected the family-reunification position: researchers are NOT exempt from the two-year sponsor rule, and the tension with the Directive is stated openly rather than resolved in the reader's favour. Removed the instruction to "check the register" of recognised centres: no such register is published. General information, not legal advice.
