Portugal, the westernmost country on the European continent, continues to attract global investors with its warm climate, affordable cost of living, and friendly immigration policies. However, recently, the Minister of the Presidency, António Leitão Amaro, publicly stated that "the period required for naturalization in Portugal is too short, far below the EU average, and should be reconsidered and revised." He proposed the following:
1. Extend the overall minimum period required to qualify for citizenship;
2. Emphasize "actual residence," requiring a longer period of physical presence in Portugal during the naturalization qualification period.
A stone cast creates a thousand ripples! Is Portugal's naturalization policy about to change? By reviewing the several amendments to the Portuguese Nationality Law between 1990 and 2024, Worldway Immigration provides an in-depth analysis of the trends in Portugal's naturalization policy.
Evolution of the Portuguese Nationality Law: The "Changes" and "Continuities" in Naturalization Thresholds
In 1981, Portugal enacted a new "Portuguese Nationality Law," replacing the old 1959 law. This law established the basic framework for immigrant naturalization, including specific requirements for legal residence in Portugal and Portuguese language proficiency. Since the 1990s, Portugal has amended the Nationality Law multiple times to adapt to social and political changes. The following is a chronological review of the major amendments, with a focus on analyzing the changes in "residence duration" and "language requirements" and their legislative logic.
Evolution of Residence Duration and Language Requirements in the Portuguese Nationality Law (1990–2024)
(I) 1994 Amendment: Tightening Naturalization Conditions and Introducing Effective Link Requirements
On August 19, 1994, the Portuguese Parliament passed Law No. 25/94, which was the first major amendment to the 1981 Nationality Law. This amendment was generally more restrictive: by extending residence requirements and adding proof of ties, it ensured that those naturalizing possessed a certain degree of linguistic and cultural integration.
Changes in Residence Duration: This amendment tightened the requirements for residence time. Previously, regardless of the applicant's country of origin, the required legal residence in Portugal for naturalization was uniformly 6 years. After the 1994 amendment, applicants were categorized into those from Portuguese-speaking countries and those from non-Portuguese-speaking countries: Applicants from official Portuguese-speaking countries still required 6 years of residence, while citizens of other countries required at least 10 years of legal residence.
Changes in Language Requirements: The 1981 law already required naturalized citizens to have "sufficient knowledge of the Portuguese language." The 1994 amendment added the requirement of "effective ties to the Portuguese community" on this basis, requiring applicants to prove actual connections to Portugal. Although the law did not explicitly define what constitutes "effective ties," Portuguese language proficiency was clearly one of the primary proofs. Additionally, the 1994 amendment stipulated that acquiring nationality through marriage required the marriage to have lasted for 3 years (previously, it could be declared upon marriage), also to ensure that the applicant had a genuine and stable connection to Portugal.
(II) 2006 Amendment: Relaxing Residence Duration and Encouraging Immigrant Integration
The logic behind the 2006 amendment was to lower the residence threshold (standardizing it to 6 years) to align with the reality of most immigrants and to facilitate the integration of "new Portuguese." In particular, allowing second-generation immigrants to obtain citizenship more easily indicated Portugal's desire for these children of immigrants, who were born in Portugal or arrived at a young age, to identify with and integrate into Portuguese society.
Changes in Residence Duration: The 2006 amendment significantly relaxed the residence duration requirements. On one hand, it standardized the statutory residence period for general naturalization to 6 years (regardless of the country of origin). On the other hand, the amendment also paid special attention to second-generation immigrants born in Portugal: it stipulated that if one of the applicant's parents had been legally residing in Portugal for 6 years, the child could apply for Portuguese nationality directly upon birth. Furthermore, the new law allowed children of immigrants born in Portugal who did not obtain nationality immediately to apply for naturalization after growing up and living in Portugal for more than 10 years (even if their status was illegal during that period).
Changes in Language Requirements: The 2006 amendment was the first to clarify the assessment standards for language proficiency through regulations: the "Implementation Rules of the Portuguese Nationality Law" issued in the same year specified "sufficient knowledge of Portuguese" as the A2 level of the Common European Framework of Reference for Languages. Applicants could prove their language proficiency by taking a naturalization Portuguese test. Additionally, the regulations accepted various equivalent proofs: for example, having completed two consecutive years of Portuguese courses in the Portuguese formal education system with passing grades, or holding a Portuguese certificate at the A2 level (or above) issued by an accredited institution, could exempt the applicant from the official language test. Applicants whose native language is Portuguese were automatically exempt from the language test requirement (deemed to already possess the required Portuguese level).
(III) 2013 Amendment: Preferential Treatment for Special Groups (Sephardic Jewish Descendants)
On July 29, 2013, Portugal passed Organic Law No. 1/2013, which was a targeted amendment. It added a special naturalization pathway: applicants who are descendants of Portuguese Sephardic Jews could apply for naturalization without meeting the residence duration requirements. However, in 2022, the government added a residence requirement to this pathway to prevent abuse, and by 2024, it officially wrote the requirement of "must have resided in Portugal for 3 years" into the law.
(IV) 2015 Amendment: Security Review and Adjustment of Diaspora Policy
In 2015, Portugal amended the law twice within one month: Organic Law No. 8/2015 was passed on June 22, and Organic Law No. 9/2015 was passed on July 29. Neither of these two amendments changed the general residence duration (which remained 6 years). The June amendment mainly added restrictive conditions regarding national security, such as explicitly stating that anyone involved in terrorist activities would not be granted naturalization. The July amendment focused on diaspora policy, broadening the acquisition of nationality for grandchildren of Portuguese emigrants.
(V) 2018 Amendment: Significantly Lowering Birthplace and Residence Requirements
The legislative logic of 2018 was very clear—to promote leniency and integration, making it easier for "children born in Portugal to be Portuguese," while allowing foreigners who have lived in Portugal for a sufficient amount of time to join Portuguese nationality faster.
Changes in Residence Duration: The 2018 amendment further relaxed the residence time threshold, reflected in two aspects:
•The residence period for general naturalization was shortened from 6 years to 5 years, greatly increasing the attractiveness and fairness for immigrants.
• The residence requirement for parents to obtain nationality for children born in Portugal was reduced to 2 years.
(VI) 2020 Amendment: Further Inclusion of Relatives and Simplification of Principles
The 2020 amendment continued the path of leniency and integration: ensuring that children born in Portugal almost automatically possess nationality, reducing the threshold for naturalization through marriage and family, while maintaining the relatively low standard of a 5-year residence period for general naturalization.
Changes in Residence Duration: The 2020 amendment did not further shorten the general residence duration, keeping it at 5 years, but it expanded the calculation and exemptions for residence in certain special cases.
Changes in Language Requirements: The 2020 amendment made a significant relaxation to the language requirements for spouses' naturalization for the first time:
• Those married or in a de facto union for 3 years and having Portuguese children with a Portuguese spouse: No longer need to prove Portuguese language proficiency when applying for naturalization.
• Those married or in a de facto union for 6 years (without common children): Similarly, they can be naturalized without providing language proof.
(VII) 2024 Amendment: Optimizing the Method of Calculating Residence
On January 4, 2024, the Portuguese Parliament officially passed the amendment to the new "Nationality Law," adding a fourth paragraph to Article 15 of the "Nationality Law": When calculating the legal residence period stipulated by this law, the time elapsed from the moment of submitting the application for a temporary residence permit is considered the legal residence period. The new Nationality Law officially took effect on April 1, 2024.
Changes in Residence Duration: The 2024 amendment did not change the number of years required for residence (still 5 years), but it made a key technical adjustment: "The starting point of the five-year residence period is moved forward to the date of submission of the residence application." In other words, the time an applicant waits for the residence card approval is also counted as a period of legal residence, significantly shortening the actual time for many people to apply for nationality.
