If you already know your route
Descent is the most common one, and it has its own guide: Portuguese citizenship by descent. For what the reform actually changed, see the 2026 nationality law.
Four routes to citizenship
in Portugal, and one that isn't
Citizenship in Portugal divides at the root: nationality law distinguishes between citizenship attributed at birth and citizenship acquired later. That distinction is not academic: attribution treats you as having been Portuguese all along, carries no residence or language test, and passes down a generation. Acquisition does not.
Four routes to citizenship in Portugal remain open. Naturalisation is the one most people arrive by and the one the 2026 reform hit hardest. Descent is the fastest where it applies and, for parents and grandparents, was left almost untouched. Birth in Portugal is conditional, not automatic. Family covers marriage, civil partnership and adoption.
A fifth card sits alongside them because it is the thing most people search for and the thing most often misdescribed: citizenship by investment. Portugal does not have one. The Golden Visa is residence by investment, and it feeds the same naturalisation clock as every other permit. We set out why in full here.
By naturalisation
The main route, and the one that changed. Seven years of legal residence for EU and CPLP nationals, ten for everyone else, counted from the date your residence card was issued rather than when you applied.
By descent
The strongest route where it exists. Parent and grandparent claims survived the reform untouched, no residence, no minimum stay. A new great-grandparent route was added, but it is conditional and demanding.
By birth in Portugal
Being born on Portuguese soil is not by itself enough and never has been. A child born to foreign parents qualifies only where a parent held legal residence for a qualifying period at the time of birth, and the claim must be formally made.
By marriage & adoption
Three years of marriage or a recognised de facto union with a Portuguese national, acquired by declaration rather than naturalisation. Full adoption by a Portuguese national confers nationality by operation of law.
By investment
Portugal has never run a citizenship-by-investment programme. The Golden Visa buys residence, which then feeds ordinary naturalisation, so investing does not shorten the clock by a single day. Since 2026 that clock is ten years for most nationalities.
| Route | Who it is for | Residence required | Language | Status |
|---|---|---|---|---|
| Naturalisation, EU & CPLP | Legal residents | 7 years1 | A2 | Open, lengthened 2026 |
| Naturalisation, all others | Legal residents | 10 years1 | A2 | Open, lengthened 2026 |
| Descent, parent | Child of a Portuguese national | None | None | Open, unchanged |
| Descent, grandparent | Grandchild of a Portuguese national | None | A2 in most cases | Open, unchanged |
| Descent, great-grandparent | Great-grandchild | 5 years in Portugal | Yes | New in 2026, conditional |
| Descent, Sephardic | Sephardic Jewish descendants | – | – | Closed to new applicants |
| Birth in Portugal | Children of foreign residents | 5 years, parental, at birth | None | Open, tightened 2026 |
| Marriage or de facto union | Spouses and partners | None | Effective ties test | Open, tightened 2026 |
| Adoption | Fully adopted children | None | None | Open, by declaration |
| Parenthood of a Portuguese child | Foreign parents | – | – | Abolished 2026 |
◇ There is no citizenship by investment in Portugal and there never has been. The Golden Visa is a residence permit; it feeds the naturalisation route and nothing else. Any page offering Portuguese "citizenship by investment" is describing a ten-year process, and should say so.
What changed in the 2026
Portuguese Nationality Law?
Lei Orgânica n.º 1/2026 was approved by Parliament on 1 April 2026 with a two-thirds majority, signed by the President on 3 May, published in Diário da República n.º 95/2026 on 18 May and entered into force the following day.1 It is the most significant revision of Law 37/81 in four decades.
What the reform took away
Naturalisation moved from five years to seven for EU and CPLP nationals and ten for everyone else. The clock now runs from the issue of the residence title, not the application. The Sephardic Jewish descent route was revoked. Naturalisation on the basis of being the parent of a child registered as Portuguese was abolished, as was naturalisation of ascendants of original Portuguese nationals. The opposition period doubled to two years, and integration requirements were extended beyond language to culture, history and national symbols, with a signed declaration of adherence to democratic rule-of-law principles.
What the reform left alone
Citizenship by descent from a parent or grandparent was not touched, still no residence requirement, still attribution rather than naturalisation. Adoption is unchanged. Dual nationality remains permitted. Permanent residency stays at five years. And every application filed on or before 18 May 2026 continues to be assessed under the previous law, including pending Sephardic files.
The open question, and the litigation
The statute is silent on one point that affects a great many people: whether residence already accrued counts toward the new period for someone who holds a permit but had not yet filed for nationality when the law came into force. The President recorded in his promulgation note that pending procedures should not be prejudiced by delays attributable to the State. How the Instituto dos Registos e do Notariado applies that in practice is still being worked out.
It is contentious enough that international firms are advising affected clients to file a claim for recognition of rights, complain to the Provedor de Justiça, and, on completing the old five-year period, lodge both a citizenship application and a subpoena for the protection of constitutional rights, freedoms and guarantees.20 We are not litigators and we do not sell that service. We mention it because you will not read it on most of the pages competing with this one, and because if you are three or four years into a five-year plan it is the single most important thing on this page.
How do you get Portuguese
citizenship by naturalisation?
Naturalisation is how most people acquire citizenship in Portugal, and since 19 May 2026 it takes seven years of legal residence for EU and CPLP nationals and ten years for everyone else.1 It does not matter which permit you held, Golden Visa, D7, D8, D2, D3, work or study all count equally toward the same clock.
The change that catches people is not the length but the counting. Time now runs from the date the Instituto dos Registos e do Notariado can see your residence title was issued, not from when you lodged the visa application or even the AIMA file. An eighteen-month AIMA delay used to be an irritation; it now postpones your naturalisation date by eighteen months.
Naturalisation requirements in 2026
- Seven or ten years of lawful residence, by nationality
- Age 18 or older, or emancipated
- A2 Portuguese, CIPLE certificate or an approved course
- Knowledge of Portuguese culture, history and national symbols
- Signed declaration of adherence to democratic rule-of-law principles
- No conviction for an offence punishable by three years or more
- No indication of a risk to national security
- Demonstrated effective connection to the Portuguese community
◇ The culture and civics requirement and the democratic declaration are both new in 2026 and are additional to, not instead of, the A2 language test. The examination format is still bedding in; expect it to firm up over the coming year.
Which permit gets you there fastest?
None of them, in the sense that the period is identical whatever route you took. What differs is how quickly you can start the clock and how easily you can keep it running. The D7 and D8 are cheap but demand real presence, and a breach of the absence rules at renewal costs you the accrued time entirely. The Golden Visa asks seven days in the first year and fourteen thereafter but takes longest to issue, which under the new counting rule is a direct cost.

Portuguese citizenship
by descent
If you have a Portuguese parent or grandparent, stop reading the naturalisation section. Citizenship in Portugal by descent is a different animal entirely: it is faster, cheaper, requires no residence in Portugal and, critically, the 2026 reform left both routes untouched. This is attribution of nationality of origin, which means you are treated as having been Portuguese since birth rather than as having become Portuguese later.
Descent from a Portuguese parent
The cleanest claim in the entire system. A child of a Portuguese national is entitled to nationality of origin regardless of where in the world they were born, with no residence requirement, no minimum stay and no language test. The work is documentary: your parent's Portuguese birth record, your own birth certificate, apostilles and sworn translations, then registration at a conservatória or consulate. Once attributed, you can pass it to your own children.
Descent from a Portuguese grandparent
Also unaffected by the reform, and still one of the most valuable ancestry routes in Europe. Grandchildren of a Portuguese national may claim nationality of origin by declaring an effective connection to the Portuguese community, in most cases evidenced with an A2 language certificate, alongside the documentary chain linking you to your grandparent. No residence in Portugal is required.
Descent from a great-grandparent, new, and demanding
The reform created a great-grandchild route that did not previously exist, then made it conditional in a way that changes its character entirely: it requires five years of legal residence in Portugal, a language certificate and proof of effective connection to the community. Read plainly, this is a residence route with an ancestry qualification attached, not an ancestry route. For a great-grandchild living in Brazil or the United States it will rarely be the practical path, the CPLP naturalisation route at seven years may well be faster.
Sephardic Jewish descent, closed
The Sephardic route, which for a decade allowed descendants of Jews expelled from Portugal in the fifteenth century to naturalise without residing, was revoked for new applicants by the 2026 reform. The Jewish Community of Lisbon stopped issuing the certificates that underpinned it in early May 2026. Applications already lodged continue to be assessed under the previous rules. A number of pages currently ranking for Portuguese citizenship still present this as an available and straightforward option. It is not. If you have been told otherwise this year, you have been told something out of date.
Attribution treats you as having been Portuguese all along. Naturalisation treats you as having arrived. The difference is more than paperwork.
Birthright citizenship:
born in Portugal
Portugal has never had unconditional jus soli. Being born on Portuguese territory does not by itself make a child Portuguese, the entitlement depends on the parents' immigration status at the time of birth, and it has to be actively claimed rather than arriving automatically with the birth certificate.
A child born in Portugal to foreign parents may be attributed nationality of origin where, at the moment of birth, at least one parent had been legally resident in Portugal for at least five years, and where a declaration to that effect is made.1 The 2026 reform lengthened that qualifying period and tightened the declaration requirement.
There is a separate and easily confused provision for people who were themselves born in Portugal to foreign parents and have since lived there, that is a naturalisation route with its own residence test, not attribution at birth.
◇ Confirmed at five years. The published text of Lei Orgânica n.º 1/2026 provides for attribution where, at the moment of birth, one parent has been legally resident in Portuguese territory for at least five years.1 Several commentaries published after the reform gave three years; they are wrong, and we said so as unresolved until we could read the statute itself. Five is the figure.
Citizenship by marriage,
partnership and adoption
The family routes to citizenship in Portugal acquire nationality by declaration rather than by naturalisation, which is why they carry no residence requirement at all. You do not have to have lived in Portugal for a day.
Marriage or de facto union
A spouse or recognised civil partner of a Portuguese national may declare for nationality after three years of marriage or of a legally recognised de facto union. There is no minimum stay in Portugal attached to it. What the 2026 reform added is an effective-ties test: alongside the relationship itself you must now evidence a genuine connection to the Portuguese community, assessed across language, cultural connection and security screening. In practice that means the paperwork now looks at you as well as at the marriage.
De facto unions must be legally recognised, which usually means a court declaration rather than simply a long relationship. That step is frequently overlooked and is the most common reason a partnership claim stalls.
Adoption
A person fully adopted by a Portuguese national acquires Portuguese nationality by declaration.1 There is no residence period, no language test and no waiting time, but the declaration must actually be made, which is the detail most summaries get wrong by describing adoption as automatic. It is the shortest route on this page, not a self-executing one.
Abolished: naturalisation through your Portuguese child
Foreign parents of a child registered as Portuguese previously had a naturalisation route of their own on the strength of that parenthood. The 2026 reform removed it, along with the naturalisation of ascendants of original Portuguese nationals. If your plan was to obtain nationality through a child born in Portugal, that plan no longer works and you are back to the residence clock.
Why citizenship in Portugal
was tightened
The reform makes little sense without the numbers behind it. AIMA recorded 1,543,697 foreign residents at the end of 2024, against roughly 421,800 in 20178, a near-quadrupling in seven years that took the foreign share of the population from about 4% to around 15%.
Under the previous five-year rule, that cohort was on course to become eligible for citizenship in Portugal in very large numbers from the late 2020s onward. The 2026 reform is best understood as a response to that arithmetic rather than to any defect in the permits themselves, which is precisely why residency was left alone while naturalisation was doubled.
◇ Brazilians are the largest foreign community in Portugal by a wide margin, followed by Indian and British nationals. Because Brazil is a CPLP member, the single biggest group of residents is also the group least affected by the reform.
Portuguese citizenship
requirements and costs
Every application for citizenship in Portugal is decided by the Instituto dos Registos e do Notariado, lodged at a conservatória, a Loja do Cidadão or a Portuguese consulate abroad. The state fees are modest. The cost that actually bites is the document chain, apostilles, sworn translations and certificates obtained from three or four countries, each with its own validity window.
Documents you will need
- Completed application to the IRN
- Full birth certificate, apostilled and translated
- Valid passport and residence card, where applicable
- Criminal record certificate from Portugal
- Criminal record certificate from every country of residence since 16
- Proof of the qualifying period, residence, marriage or descent
- CIPLE A2 certificate or approved course completion
- Evidence of effective connection to the Portuguese community
- Declaration of adherence to democratic rule-of-law principles
- Ancestor's Portuguese birth or baptism record, for descent claims
| Route | Qualifying period | Language | Decided by |
|---|---|---|---|
| Naturalisation, EU & CPLP | 7 years' residence | A2 + civics | IRN |
| Naturalisation, others | 10 years' residence | A2 + civics | IRN |
| Descent, parent | None | None | Conservatória or consulate |
| Descent, grandparent | None | A2 in most cases | Conservatória or consulate |
| Descent, great-grandparent | 5 years' residence | Yes | IRN |
| Birth in Portugal | Parental residence at birth | None | Conservatória |
| Marriage or de facto union | 3 years | Effective ties | IRN |
| Adoption | None | None | By declaration |
◇ Portuguese state fees for nationality applications are set by regulation and are modest relative to the document costs, descent applications are frequently free of application fee. Budget realistically for apostilles, certified translation into Portuguese by a sworn translator, and re-issuing certificates whose validity expires while you wait. Fees and formats change; confirm against the IRN before lodging.
Portuguese citizenship for
Americans, Britons and Brazilians
Citizenship in Portugal is compatible with dual nationality, so for most people the question is not whether you may keep your existing passport but how long the Portuguese one takes and what it costs you at home.
Portuguese citizenship for US citizens
Americans naturalise at ten years under the 2026 law unless they hold another qualifying nationality. Portugal allows dual citizenship and the United States does not require renunciation, so most US clients hold both. The tax position does not improve: the United States taxes on citizenship, so acquiring a Portuguese passport changes nothing about your US filing obligations, and renouncing US citizenship is a separate decision with an exit tax attached. The descent routes are the exception worth checking, a Portuguese grandparent removes the ten-year wait entirely.
Portuguese citizenship for UK citizens
Britons also naturalise at ten years, having lost EU citizenship at Brexit, which is precisely why demand from the UK has grown. The United Kingdom permits dual nationality, so there is nothing to give up. For British applicants the practical friction is documentary: ACRO criminal record certificates, apostilles under the Hague Convention, and full-form rather than short-form birth certificates.
Portuguese citizenship for Brazilians and CPLP nationals
The one genuine nationality advantage in the system. Nationals of the Community of Portuguese Language Countries, Brazil, Angola, Cape Verde, Mozambique, Guinea-Bissau, São Tomé and Príncipe, Timor-Leste and Equatorial Guinea, naturalise at seven years rather than ten.1 Brazilians are already the largest foreign community in Portugal by a wide margin, and for a Brazilian family the language requirement is not a requirement at all. Portugal and Brazil also maintain a reciprocal equality-of-rights statute that sits alongside nationality and is frequently confused with it. It is not citizenship, and it does not produce an EU passport.
The seven-year track applies to CPLP nationals whatever route they hold, which is why a CPLP nationality acquired before you naturalise changes the finish line: Portugal citizenship for CPLP nationals walks through the two scenarios, and CPLP citizenship: one language, three passports sets out the São Tomé–Brazil–Portugal sequence and its caveats.
Seven ways a citizenship
application fails
Applications for citizenship in Portugal fail on evidence and timing far more often than on eligibility. These are the ones we see.
1. Counting from the wrong date
Applicants count from arrival, or from the visa, or from the AIMA submission. The clock runs from the issue of the residence title. Getting this wrong by a year means filing early and being refused.
2. A gap in the residence chain
A lapsed renewal, a missed AIMA appointment or a breach of the absence limits can break continuity. The period must be lawful and continuous, an expired card in the middle of it can reset everything.
3. Documents timing out
Criminal record certificates and apostilles carry short validity, often around three months. Files assembled over a long period routinely arrive with the earliest documents already expired.
4. Thin effective-connection evidence
Now required on the grandparent, great-grandparent and marriage routes, and no longer satisfied by a certificate alone. Language, visits, family ties, property and community participation all carry weight, assemble it deliberately.
5. An unrecognised de facto union
A long relationship is not a legally recognised union. Without the court declaration, the three-year partnership route does not open, however genuine the relationship.
6. Relying on a closed route
The Sephardic route is revoked and naturalisation through a Portuguese child is abolished. Both are still described as available on pages ranking today. Plans built on either need rebuilding.
7. Assuming the old clock still applies
If you did not file on or before 18 May 2026, you are on the new periods. Whether accrued residence counts toward them is unresolved, and that uncertainty is precisely why the timing of your filing should be taken seriously.
What we do about it
We date the clock from the title, audit the residence chain for gaps before anything is lodged, sequence documents backwards from the appointment, and build the effective-connection file over years rather than assembling it in a fortnight.

Citizenship in Portugal is a statutory question, so this page is sourced to statute wherever possible. We previously flagged the parental residence period for birthright claims as unresolved; having read the published text, it is five years, and the page now says so. One question genuinely remains open, whether residence already accrued counts toward the new naturalisation periods, and we have left that flagged rather than guessing.
