Among the most talked-about global citizenship changes in 2025 is Portugal’s decision to double its residency requirement and end automatic birthright citizenship.
It’s just one example of how countries are tightening or restructuring access to nationality this year.
As governments rethink how and why they grant citizenship—whether through birth, investment, or merit—global expats and high-net-worth individuals must stay informed.
This guide outlines the most significant citizenship changes in 2025, including:

In May 2025, Argentina implemented a major shift in its nationality law by ending automatic birthright citizenship (jus soli).
Previously, any child born on Argentine soil regardless of the parents’ immigration status, was eligible for immediate citizenship.
Under the new rule, children born in Argentina to foreign parents must now complete two years of legal residency before qualifying for Argentine citizenship.
This change directly impacts expat families, migrant communities, and those who previously viewed Argentina as a strategic destination for birth tourism.
While the country still maintains a relatively open path to naturalization, the revised law reflects a growing trend among governments to limit automatic access to citizenship and place more emphasis on integration or long-term presence.
The new requirement does not apply retroactively, but going forward, it introduces a waiting period that expats and global families must now factor into their residency and citizenship planning in Argentina.
Portugal’s 2025 citizenship changes mark one of the most comprehensive overhauls in Europe this year with the doubling of the general residency requirement for naturalization, from 5 years to 10 years.
A reduced 7-year requirement is still available for nationals of Portuguese-speaking countries like Brazil, Angola, and Mozambique.
Another major shift affects children born in Portugal. Birthright citizenship is no longer automatic.
Foreign parents must now have at least 3 years of legal residence before their child can qualify for Portuguese nationality, ending a long-standing provision that attracted migrant families.
In addition, Portugal is introducing a more rigorous integration process.
Applicants must now demonstrate not only Portuguese language skills, but also a working knowledge of the country’s culture and democratic values.
These elements will be evaluated through new standardized testing.
The reforms are not retroactive—applications filed under the current rules (i.e., with 5 years of residency) will still be processed accordingly.
As of mid-2025, the changes have passed Cabinet approval and are awaiting final parliamentary confirmation, expected later this year.
The United Arab Emirates continued refining its discretionary citizenship framework in 2025, further expanding eligibility under its merit-based citizenship program.
Originally launched in 2021, the initiative was designed to attract global talent and recognize individuals who contribute meaningfully to the UAE’s national development.
In 2025, the program now formally includes a broader range of eligible categories, such as prominent scientists, artists, cultural innovators, and select investors—all assessed under the umbrella of national interest.
The criteria emphasize global impact, sustained achievement, and alignment with the UAE’s strategic goals, such as technological innovation, cultural diplomacy, and knowledge-based economic growth.
The naturalization process for long-term residents has also become more streamlined.
Qualified individuals no longer need to give up their original citizenship, and the selection process now includes clearer benchmarks tied to measurable contributions in their fields.
While the pathway remains by invitation only, the increased visibility and structure around eligibility have made this once-elusive option more accessible to accomplished expats who have built their careers in the UAE.
On May 24, 2025, Italy enacted Law No. 74, formalizing significant citizenship changes to its legislation, including the introduction of a generational limit.
Individuals born abroad with Italian ancestry will no longer be eligible for automatic recognition unless they meet specific conditions, such as:
Special provisions also apply to minor children:
In February 2025, the UK government updated its guidance on the good character requirement for British citizenship, introducing new restrictions based on how an individual entered the country.
As of February 10, 2025, applicants who entered the UK illegally or via dangerous routes such as small boats or concealed in lorries, will now normally be refused citizenship, regardless of how long ago they arrived.
While the Home Office still retains discretionary power, this language shift signals a tougher stance.
The changes apply to both adults and children over the age of 10, and are particularly relevant to refugees and asylum seekers who were granted legal status after irregular entry.
Prior to the update, most breaches of immigration law were typically disregarded after 10 years; this new guidance overrides that leniency for cases involving irregular arrival.
Applications submitted before February 10 are assessed under the previous framework.
However, for those applying under the new rules, entry method now weighs heavily, creating greater uncertainty for individuals with complex immigration histories.
These changes reflect the UK’s broader move toward tightening migration pathways, particularly for individuals who did not arrive through formal channels, even if they later gained lawful residence.
In 2025, Turkey introduced regulatory refinements to its citizenship by investment program, not by raising financial thresholds, but by tightening oversight and procedural requirements.
The minimum investment amounts remain unchanged:
However, the government has increased scrutiny in several areas:
These measures are aimed at improving transparency, minimizing abuse, and aligning with international compliance standards.
While the Turkish CBI program remains one of the fastest in the world with typical processing times of 3 to 6 months, it now requires a higher level of personal involvement from applicants.
Austria’s discretionary citizenship framework faced a major reset in 2025, in response to growing EU scrutiny and domestic demands for transparency, the government has introduced both stricter oversight and broader legal reforms under its 2025–2029 national program.
For citizenship granted by exception (e.g., to athletes, scientists, cultural icons, and high-impact investors), the process now involves:
Beyond discretionary citizenship, Austria has also made significant changes to its general naturalization criteria:
Saint Kitts & Nevis, the world’s longest-running citizenship by investment program, enacted major reforms in 2025 to reinforce credibility and align with global compliance trends:
While Canada has not introduced new citizenship requirements per se in 2025, it has enacted major legislative reforms affecting both skilled migrants and Canadian citizens abroad:
In 2025, the United States remains in the midst of a highly politicized debate over birthright citizenship, with proposed legislation aiming to restrict US citizenship only to children born to US citizens or lawful permanent residents.
Key developments include:
Despite these moves, no law has passed, and the constitutional guarantee remains intact.
The citizenship changes in 2025 is marked by more selective, compliance-driven policies across multiple jurisdictions.
From Europe to the Caribbean, governments are raising the bar through language, integration, and physical presence requirements, while narrowing eligibility for descent and discretionary grants.
For expats and high-net-worth individuals, these shifts make it critical to plan early, stay informed, and align mobility strategies with the new regulatory climate.
