Portuguese citizenship remains available through naturalisation, marriage, ancestry, birth under qualifying conditions, and other nationality-law routes, but Portugal’s 2026 reform has significantly extended the residence period for most naturalisation applicants.
Following the 2026 amendments to Portugal’s Nationality Law, most foreign nationals now generally need 10 years of legal residence before applying for Portuguese citizenship. Citizens of European Union member states and CPLP countries may qualify after 7 years of legal residence.
Portuguese citizenship provides full European Union citizenship rights, including the ability to live, work, study, retire, and establish a business across all 27 EU member states. A Portuguese passport is described as offering visa-free or visa-on-arrival access to approximately 185+ destinations, including the Schengen Area, the UK, Japan, Singapore, and Hong Kong.
Portugal generally permits dual and multiple citizenship, subject to the rules of the applicant’s original country. Portuguese citizenship is permanent, does not require renewal, and can generally be passed to future generations.
Main Routes to Portuguese Citizenship
Portuguese citizenship can be acquired through several routes:
- Naturalisation after legal residence
- Marriage or de facto union with a Portuguese citizen
- Portuguese ancestry
- Birth in Portugal under qualifying conditions
- Repatriation for descendants of Sephardic Jews expelled from Portugal
- Other provisions of Portuguese nationality law
Naturalisation remains the main route for most foreign nationals. Applicants generally need to hold legal residence for the required period, show knowledge of Portuguese, meet integration requirements, maintain a clean criminal record, and comply with immigration and nationality rules.
The 2026 reform was introduced through Lei Orgânica n.º 1/2026, de 18 de maio. Under the new rules, most applicants must complete 10 years of legal residence before applying. EU and CPLP citizens may qualify after 7 years.
Citizenship by Marriage
A spouse of a Portuguese citizen can apply for citizenship after three years of marriage, even if they do not live in Portugal.
Applicants must prove that the marriage is legitimate and show a connection to the Portuguese community. Examples given include working for a local company, studying at a university, or owning property in Portugal.
Citizenship by Birth
Portugal does not grant automatic citizenship solely by birth on Portuguese territory.
A child born in Portugal to foreign parents may be eligible for citizenship if at least one parent has been a legal resident for at least one year. Children under 18 adopted by Portuguese citizens may also obtain nationality.
Citizenship by Descent
Applicants may claim Portuguese nationality if at least one parent, grandparent, or great-grandparent is a Portuguese citizen.
They must provide documents proving the family relationship, such as birth certificates translated into Portuguese.
Sephardic Jewish Ancestry
Direct descendants of Sephardic Jews expelled from Portugal in the 15th century may apply for citizenship.
Applicants must provide evidence of ancestry through an accredited Sephardic community. Supporting documents may include marriage certificates, death certificates, wills, family tree records, or synagogue documents.
The article lists descendants as living in countries including Israel, France, the United States, Canada, Turkey, Argentina, Russia, Italy, Germany, Ukraine, Australia, Spain, Brazil, and Belarus.
Residency Routes Toward Naturalisation
The first step for most naturalisation applicants is obtaining Portuguese residency. Once residency is granted, the qualifying residence period begins.
Common residency routes include:
- Work Visa — D1 and D3: D1 applies to contracted employees; D3 is for highly qualified professionals. D3 requires a job offer from a Portuguese employer with a minimum salary of €1,441.
- Entrepreneur Visa — D2: For applicants starting a business or working as self-employed in Portugal.
- Student Visa — D4 and D5: D4 applies to undergraduate and graduate students; D5 applies to short-term academic exchanges.
- Family Reunification Visa — D6: For family members of Portuguese citizens or residents.
- Financial Independent Visa — D7: For financially independent applicants with stable external income, such as dividends, rent, or pensions. The minimum confirmed income cited is €920 per month.
- Digital Nomad Visa: For remote professionals employed outside Portugal while living in the country. The minimum confirmed income cited is €3,480 per month.
- Golden Visa: For investors in Portugal’s economy. The article cites a minimum non-refundable €250,000+ investment in culture and art, or €500,000+ through a fund investment.
Most residence routes, such as the D7 Visa, Digital Nomad Visa, work visas, or family reunification, typically involve residing in Portugal for at least 183 days per year.
The Portugal Golden Visa has a much lower physical presence requirement. Investors need to spend only 14 days in Portugal every two years.
Application Process
The Portuguese citizenship process generally involves seven steps:
- Identify the correct citizenship route.
- Gather supporting documents.
- Meet the relevant eligibility requirements.
- Submit the citizenship application.
- Undergo government review.
- Receive Portuguese citizenship if approved.
- Apply for Portuguese identity documents.
Supporting documents may include:
- Passport and identity documents
- Birth certificates
- Marriage certificates
- Ancestry records
- Proof of legal residence
- Criminal record certificates
- Portuguese language certificates
- Other evidence required by the authorities
Foreign documents generally require translation and legalisation or apostille.
Applications may generally be submitted online through a Portuguese lawyer or solicitor, in person at an authorised nationality office, or by post. Authorities then review the application, verify documents, conduct background checks where applicable, and may request additional information.
Once nationality is approved and registered, the applicant becomes a Portuguese citizen. The new citizen may then apply for a Portuguese Citizen Card, known as the Cartão de Cidadão, and later a Portuguese Electronic Passport, or PEP.
Costs
The article lists the following typical costs:
- Citizenship application fee: €250
- CIPLE Portuguese language exam at A2 level: €85
- Portuguese Citizen Card, standard issuance: from €18
- Portuguese Electronic Passport: €65
Final costs depend on the route, country of origin, number of documents requiring legalisation, and whether professional assistance is used. Applicants may also need to budget for translations, apostilles, criminal record certificates, and related documentation.
CPLP Citizens and the 7-Year Route
The 2026 reform created a shorter naturalisation period for citizens of CPLP countries. CPLP citizens may generally become eligible for Portuguese citizenship after 7 years of legal residence, compared with 10 years for most other foreign nationals.
The CPLP, or Community of Portuguese Language Countries, includes:
- Portugal
- Brazil
- Angola
- Mozambique
- Cape Verde
- Guinea-Bissau
- São Tomé and Príncipe
- Timor-Leste
- Equatorial Guinea
São Tomé and Príncipe is described as particularly relevant because it is currently the only CPLP member state offering a dedicated citizenship by investment program, with a minimum contribution threshold of $90,000.
In theory, a long-term strategy could involve:
- Obtaining citizenship of São Tomé and Príncipe
- Securing legal residence in Portugal through an eligible immigration route
- Maintaining Portuguese residence and meeting language and integration requirements
- Applying for Portuguese citizenship after the 7-year residence period applicable to CPLP nationals
Portuguese citizenship is not automatically granted to CPLP citizens. A São Tomé and Príncipe passport does not provide residence rights in Portugal and does not remove the requirement to obtain and maintain a Portuguese residence permit.
Unclear Treatment of Mid-Residence CPLP Citizenship
The article discusses a scenario where someone is already legally resident in Portugal and later acquires São Tomé and Príncipe citizenship.
There is currently no established administrative practice, official guidance, or court precedent on that situation. Portuguese lawyers consulted for the article believe such an applicant may potentially qualify for the shorter 7-year period for CPLP nationals.
According to that interpretation:
- The qualifying residence period should continue from the date the applicant first obtained a Portuguese residence permit.
- The residence clock would not restart from the date São Tomé and Príncipe citizenship is acquired.
- It may not be necessary to replace existing Portuguese residence documents with documents linked to the new passport.
The article stresses that Portugal’s 2026 nationality reform is recent. The first real-world cases under these scenarios are expected to reach the citizenship application stage only in future years, and administrative practice may evolve as authorities issue guidance or apply the rules in practice.
The key decision point is that Portuguese citizenship planning now depends heavily on nationality, residence route, physical presence requirements, language ability, family background, and long-term goals. For most foreign nationals, the standard naturalisation period is now 10 years, while EU and CPLP citizens may have a shorter 7-year path if they meet the residence and application requirements.
