The article outlines significant changes in Portugal's immigration and nationality laws from December 2024 to September 2025. Key developments include:

1. Technical Amendments: In February 2025, Law No 9/2025 updated the Law on Foreigners (Law 23/2007) to comply with EU Entry/Exit regulations, clarifying the issuance and validity of residence authorizations for nationals from Portuguese-speaking countries.

2. Tightened Nationality Rules: A government proposal in June 2025 suggested stricter nationality acquisition criteria, including longer residence requirements (seven years for Portuguese speakers, ten years for others), mandatory language and civic tests, and revised family reunification criteria.

3. Parliamentary Approval: In July 2025, Parliament approved a reform package that codified these changes, including longer residence thresholds and enhanced integration requirements.

4. Constitutional Court Intervention: In August 2025, the Constitutional Court struck down several provisions of the new immigration law, particularly those limiting family reunification, citing violations of constitutional rights. This led to political debates and a return of the decree to Parliament for reconsideration.

5. Ongoing Revisions: Following the court's decision, the government initiated efforts in September 2025 to amend the immigration law in accordance with constitutional standards.

Overall, this period marks a significant legislative shift in Portugal's approach to immigration and nationality, characterized by both reforms and judicial challenges.
