At a Glance
- Portugal’s nationality law changed on 19 May 2026, when Lei Orgânica 1/2026 entered into force one day after publication in the Diário da República.
- Naturalisation now requires seven years of legal residence for nationals of EU member states and Portuguese-speaking countries, and ten years for all other nationalities, including US citizens. The previous requirement was five years for everyone.
- Nationality applications already filed with the registries on or before 18 May 2026 continue under the previous regime, including the five-year requirement. The protection attaches to the filed application, not to residence already accumulated.
- Residence years no longer only need to add up. Under the amended Article 15 they must fall within a maximum window of nine years for EU and CPLP nationals and twelve years for everyone else.
- The Government was required to update the Regulamento da Nacionalidade within 90 days. That deadline passed on 16 August 2026 without publication, which leaves both the new civics requirement and the treatment of residence already accumulated without a defined procedure.
- Permanent residence and EU long-term resident status after five years of legal residence were not changed by this law.
Lei Orgânica 1/2026 is the statute that amended Portugal’s 1981 Nationality Law, Lei n.º 37/81, and it took effect on 19 May 2026. Most coverage of the Portugal nationality law has settled on a single figure: ten years instead of five. That figure is correct, and for readers currently holding a Portuguese residency position it is also the least useful part of the story.
The more consequential questions sit underneath it: which residence time counts, what the transitional rule actually protects, and whether the procedure for the new integration requirement exists yet. Those questions determine whether a plan built in 2023 or 2024 still arrives where it was meant to arrive, and two of the three do not yet have a clean answer.
What did Portugal’s 2026 nationality law change?
Lei Orgânica 1/2026 raised the naturalisation residence requirement from a universal five years to seven years for EU and CPLP nationals and ten years for all other nationalities. It also broadened the integration requirement beyond language, and changed how residence periods are counted.
| Before 19 May 2026 | From 19 May 2026 | |
|---|---|---|
| EU and CPLP nationals | 5 years | 7 years |
| All other nationalities, including US citizens | 5 years | 10 years |
| Language requirement | Portuguese language proficiency | Language, plus culture, history, national symbols, and fundamental rights and duties |
| Declaration | None | Formal adherence to democratic principles |
| Counting of residence | Periods summed | Periods summed, but within a 9 or 12-year maximum window |
| Criminal record bar | Narrower | Prison sentence above three years for specified crimes disqualifies |
| Permanent residence | 5 years | 5 years, unchanged |
Article 6 of the Nationality Law, as amended, sets the periods in plain terms: seven years for nationals of Portuguese-speaking countries and citizens of EU member states, ten years for nationals of other countries. For an American investor, the applicable figure is ten.
A point of terminology is worth fixing early, because much of the published commentary blurs it. Lei Orgânica 1/2026 is a short amending statute of eight articles. The residence periods and the definition of legal residence sit in the Nationality Law it amends, at Articles 6 and 15, while the transitional rule, the regulation deadline and the entry into force sit in the amending law itself, at Articles 7, 4 and 8.
Who is still covered by the old five-year rule?
Only applicants whose nationality application was already filed with the Portuguese registries on or before 18 May 2026. Article 7 of Lei Orgânica 1/2026, headed Aplicação no tempo, provides that administrative procedures pending on the date the law entered into force continue under the previous version of Lei n.º 37/81, including the five-year residence requirement.
The filing date determines the applicable law. Residence accumulated before the law changed does not, by itself, secure the old treatment, and this is where most of the confusion in the market currently sits.
The distinction has consequences. An investor who subscribed to a fund in 2021, received a residence permit in 2023, and expected to file for naturalisation in 2028 was, on 18 May 2026, three years from the finish line. On 19 May 2026 that same investor was measuring against a ten-year requirement with no filed application to shelter behind.
Does residence completed before May 2026 count toward the new period?
The law does not say, and that silence is the central unresolved question for anyone partway through a Portuguese residency plan.
The amended Article 15 defines legal residence by reference to holding a regularised status under any of the titles, visas or authorisations provided for in the immigration and asylum regimes. It says nothing about how time spent waiting for a decision is treated. That matters, because Lei Orgânica 1/2024 had introduced a rule allowing residence to count from submission of the residence permit application, a change made specifically to stop AIMA’s processing backlog penalising applicants. The republished Article 15 does not carry that language forward.
Published commentary has divided accordingly. Some legal publications state plainly that the period now runs from issuance of the residence title rather than from the start of the procedure. Others, including firms advising international investors, hold that administrative delay will not be counted against applicants. A third group records the point as pending the updated regulation. All three readings are offered with confidence, which is usually a sign that the underlying text does not settle the question.
Anyone whose plan turns on this should take advice on their own file rather than reason from the general case. The variance between individual residence histories is wide enough that general guidance, including this article, cannot substitute for it.
Must the residence years be continuous?
No, but they must now fall within a fixed window, and this is the change receiving the least attention relative to its consequences.
Article 15(3) provides that periods of legal residence may be summed whether consecutive or interrupted, but only where they fall within a maximum interval of six, nine or twelve years, according to whether the applicant is stateless, a national of a Portuguese-speaking country or EU member state, or a citizen of another country.
For an American investor the arithmetic is ten years of legal residence accumulated within a twelve-year window, which leaves roughly two years of tolerance for gaps across the whole period. Anyone who held a Portuguese residence permit through the AIMA transition knows that gaps are not hypothetical. Renewal delays, lapsed cards awaiting reissue, and periods where status sat in administrative limbo are common features of files opened between 2021 and 2024.
Under a five-year requirement a gap was an inconvenience. Under a ten-year requirement inside a twelve-year window, a sustained lapse can put naturalisation out of reach entirely. This is the provision most worth checking against an actual residence history, and the one least likely to appear in general coverage.
Why is the new citizenship requirement still without a procedure?
Because the Government missed its own deadline. Article 4 required it to make the necessary amendments to the Regulamento da Nacionalidade within 90 days of publication, a deadline that fell on 16 August 2026 and passed without action.
The practical result is that a legal requirement exists without the procedure that operationalises it. The law obliges applicants to demonstrate knowledge of Portuguese culture, history, national symbols, and fundamental rights and duties. It does not specify who administers that assessment, what it covers, or what constitutes a pass.
In the absence of a common procedure, individual registry offices apply their own judgment, which across many offices produces inconsistent outcomes, and some files are reportedly being held pending clarification. For a country that has spent two years rebuilding institutional credibility after the SEF transition, this is an unhelpful gap.
What did the 2026 nationality law not change?
Permanent residence and EU long-term resident status after five years of legal residence, both of which this law left untouched. It addressed naturalisation without altering the residence framework beneath it.
That distinction deserves more weight than it usually receives. For a family whose actual objective is the right to live, work, study, and access healthcare in Portugal, and to move through the Schengen area without friction, permanent residence at five years delivers most of the practical benefit. Citizenship adds an EU passport, transmissibility to descendants, and permanence that no administrative decision can withdraw. Those additions are meaningful, and for many families they are the point, but they are now further away.
The honest framing is that Portuguese residency has become a good asset with a longer option attached, rather than a five-year path to an EU passport. Investors who entered on the second understanding have a genuine grievance. Investors evaluating entry today should price the first.
What to watch between now and the end of 2026
Two developments will clarify most of what is currently open. The first is publication of the amended Regulamento da Nacionalidade, which should define both the integration assessment and the counting mechanism. The second is any administrative guidance from the IRN on how residence completed before 19 May 2026 is treated, which will determine what the route from residence to citizenship now looks like in practice. Representations on the transitional regime have already been made to Parliament, and pressure from affected applicants is unlikely to subside while the regulation remains outstanding.
Until those resolve, planning should be built on what the law states rather than on how it might be interpreted. The five-year permanent residence position is firm, and so is the ten-year naturalisation requirement. What sits between them is not yet settled, and any adviser presenting it as settled is offering confidence the record does not support.
Frequently Asked Questions
Q: How many years of residence does Portugal now require for citizenship? Ten years of legal residence for most nationalities, including US citizens, and seven years for nationals of EU member states and Portuguese-speaking countries. These periods took effect on 19 May 2026 under Lei Orgânica 1/2026, replacing the previous five-year requirement.
Q: Does the old five-year rule still apply to me? Only if your nationality application was already filed with the Portuguese registries on or before 18 May 2026. The transitional provision in Article 7(2) protects pending applications, not residence accumulated before the law changed.
Q: Does residence I completed before May 2026 count toward the ten years? The law does not say. The amended Article 15 defines legal residence without addressing how time awaiting a decision is treated, and the regulation that should resolve it has not been published. Published commentary is divided. Anyone affected should obtain advice specific to their own residence history rather than rely on general guidance.
Q: Is the Portugal Golden Visa still worth pursuing after the nationality change? That depends on what the investment is meant to achieve. Permanent residence after five years was not affected, so the mobility, healthcare, and education benefits arrive on the same schedule as before. If the sole objective was an EU passport in five years, the arithmetic has changed and should be reassessed honestly.
Q: When will the new Portuguese language and civics test be defined? No date has been announced. The Government was required to update the Regulamento da Nacionalidade within 90 days of publication, a deadline that passed on 16 August 2026 without action. Until the regulation is published, procedures will vary between registry offices.
Q: Do my ten years of residence have to be continuous? No, but they must fall within a maximum window of twelve years for most nationalities and nine years for EU and CPLP nationals. Periods of legal residence can be added together, consecutive or interrupted, provided the whole history sits inside that window.
Q: Did the 2026 nationality law change the Golden Visa investment requirements? No. Lei Orgânica 1/2026 amends the Nationality Law. The residency-by-investment framework, including the CMVM-regulated fund route at €500,000, was not part of this legislation.
At Portugal Panorama we spend most of our time on the question this article cannot answer, which is what a change like this means for one particular family with one particular residence history and one particular set of objectives. If you are holding a Portuguese residency position and want to understand where you now stand, or reconsidering whether to open one, we would be glad to work through it with you.
