The 2026 nationality law rewrote the descent route

One date decides which law applies

Article 7.º n.º 2 of Lei Orgânica n.º 1/2026 provides that administrative procedures already pending at the date the law entered into force continue to be governed by Lei n.º 37/81 in its prior wording. The cut-off is therefore whether the application had already been filed on 19 May 2026.

That single provision splits the whole subject in two. A file opened in March 2026 runs on the old rules, including the old five-year naturalisation requirement. A file opened in June 2026 does not. Any advice found online that does not state which side of that line it is describing is unusable, whatever else it gets right.

The grandchild route kept its shape and gained two conditions

Under article 1.º n.º 1 alínea d) of the republished law, a person with at least one ascendant of Portuguese nationality in the second degree in the direct line, meaning a grandparent, who has not lost that nationality, is Portuguese by origin, provided they declare that they wish to be Portuguese and hold ties of effective connection to the national community.

Two features of the 2026 wording do real work. First, the grandparent must hold Portuguese nationality originária. Second, article 1.º n.º 3 makes attribution under alínea d) conditional on the applicant also satisfying the requirements in article 6.º n.º 1 alíneas c) to h).

What alíneas c) to h) now include

Among them is proof, by test or by certificate, of sufficient knowledge of the Portuguese language and culture, of national history and of the national symbols. A descent claim that would have turned on documents alone now turns on documents and an examinable body of knowledge.

A naturalised grandparent does not open the route

This is the hard edge of the descent route, and it is easy to read past. The route requires a grandparent who is Portuguese by origin. A grandparent who acquired Portuguese nationality by naturalisation is not within alínea d), however genuinely Portuguese the rest of the family history is.

The practical consequence is that the first document to find is not the applicant's birth certificate. It is whatever establishes how the grandparent held the nationality, because that fact decides whether there is a claim at all.

Naturalisation timelines: five became seven or ten

Article 6.º n.º 1 alínea b), as rewritten, requires at least seven years*, source: Diário da República, 1.ª série, in force 19 May 2026, read August 26, 2026 of legal residence for nationals of Portuguese-speaking countries and citizens of EU Member States, and ten years*, source: Diário da República, 1.ª série, in force 19 May 2026, read August 26, 2026 for nationals of other countries. The previous general requirement was five years*, source: Diário da República, read August 26, 2026.

United States, United Kingdom and Canadian nationals fall in the longer band. For an American who moves to Madeira on a D7 in 2026 and intends to naturalise, the horizon is now a decade rather than half of one, and every published timeline built on the old figure understates it by that margin.

The great-grandchild route is a naturalisation, not an attribution

Article 6.º n.º 8 allows descendants in the third degree in the direct line of Portuguese nationals by origin to be granted nationality by naturalisation with the general residence requirement waived, provided they have had legal residence in Portugal for at least five years*, source: Diário da República, 1.ª série, in force 19 May 2026, read August 26, 2026.

The wording rewards careful reading. The general residence requirement is waived and a residence requirement remains, because the waiver removes the seven-or-ten-year rule and substitutes a shorter one. A great-grandchild still has to live in Portugal to use it. A grandchild does not have to live here at all.

What nationality by origin gives, and what it does not

Attribution under article 1.º n.º 1 alínea d) is nationality by origin. It is retroactive to birth, transmissible to the holder's own children, and carries full EU citizenship with the right to live and work anywhere in the Union. It requires no prior residence in Portugal.

It confers no tax status whatsoever. Tax residence is a separate test under article 16.º of the CIRS, and holding a Portuguese passport while living in Ohio does not make a person a Portuguese taxpayer. It also does nothing for the incentive regimes: IFICI turns on becoming tax resident and on an eligible activity, not on nationality.

Why the pre-2026 guidance is wrong rather than merely dated

An earlier attempt at the same reform was blocked. The Tribunal Constitucional found norms of Decreto n.º 17/XVII unconstitutional in December 2025 and the decree was returned without promulgation. Lei Orgânica n.º 1/2026 is the re-passed version that completed the process: approved on 1 April 2026, promulgated on 3 May, in force on 19 May.

That sequence produced a period in which the reform was correctly reported as having failed. Guidance written during it is not out of date by an increment; it describes an outcome that then reversed. Anything on Portuguese nationality carrying a date between December 2025 and May 2026 needs re-reading against the law that actually passed.

The regulation that was due in August 2026

Article 4.º of Lei Orgânica n.º 1/2026 requires the Government to amend the Regulamento da Nacionalidade Portuguesa, annexed to Decreto-Lei n.º 237-A/2006, within 90 days*, source: Diário da República, 1.ª série, in force 19 May 2026, read August 26, 2026 of publication. That falls in the middle of August 2026.

Whether that amendment has in fact been published was not established for this page. It matters, because the Regulamento is where the procedural detail lives: what evidence is accepted for effective connection, and how the language, culture and history requirement is discharged in practice. Until it is confirmed, the operative rule is clear and the paperwork around it is not.

Madeira changes nothing about this, which is the useful part

Nationality is a national competence. Declarations are processed through the Conservatória dos Registos Centrais wherever the applicant lives, and there is no Madeira variant, no regional office with different rules and no island advantage.

What the island changes is what happens next. A person who obtains nationality by descent arrives as an EU citizen, so the whole visa apparatus falls away and the move becomes a registration at the câmara municipal rather than a consular application. No sourced current processing time for nationality declarations was obtainable for this page, and figures published elsewhere are not traceable to the Conservatória.
