The Second Passport Nobody Talks About and Almost Everyone Qualifies For

There is a category of second passport that receives almost no attention in the mainstream Plan B conversation, despite being the most accessible route available to the largest number of people. It requires no investment, no minimum stay in a foreign country, and in most cases no language test. It requires only that you have the right ancestor and the documents to prove it.

Citizenship by descent, known legally as jure sanguinis, is the legal recognition that citizenship is a heritable right passed from parent to child across generations. More than fifty countries recognise it in some form. The most significant for people with European heritage are Ireland, Italy, Poland, and Germany, each offering pathways to a second passport and full European Union rights of residence and movement.

Over 1.2 million citizenship by descent applications were filed across Europe alone in 2025. For the millions who qualify and have not yet started the process, the more relevant development has been the rule changes closing certain windows that were previously wide open.

Ireland: The Most Accessible EU Passport Available

If you have at least one grandparent who was born on the island of Ireland, you are entitled to register as an Irish citizen through the Foreign Births Register. An estimated 70 million people worldwide claim Irish ancestry, compared to Ireland’s population of approximately 5.1 million.

Irish citizenship carries the full rights of an EU passport, including the right to live and work in all 27 member states. There is no language test and no residency requirement at any point in the process. Processing currently takes approximately 12 months from submission of a complete application.

One detail that carries significant practical weight: if you register as an Irish citizen before your children are born, they inherit your Irish citizenship automatically. For anyone with children or planning to have them, registering now rather than later is not a minor consideration.

Italy: A Major Rule Change You Need to Know About

Italy’s citizenship by descent program was, until March 2025, one of the most generous in the world. Under the previous rules, there was no generational limit, and descendants of ancestors who emigrated in the 1890s could in principle claim citizenship.

That era ended with Decree-Law No. 36 of March 2025, upheld by the Italian Constitutional Court in March 2026. New applications are now generally limited to descendants of Italian parents or grandparents. Great-grandparent claims are no longer valid for applications filed after the law came into force.

Italian citizenship by descent remains valuable and widely accessible for anyone with a parent or grandparent who held Italian citizenship. Italy allows dual citizenship, imposes no language test for descent applicants, and processing runs two to four years at consulates. A judicial route through Italian courts is available and often faster for certain cases.

Poland: The Deepest Generational Reach in Europe

Poland’s citizenship by descent program has no strict generational limit. Any descendant of a person who held Polish citizenship after 1920 may be eligible to claim, provided the chain of citizenship was never broken by renunciation or disqualifying events.

For the large communities of Polish descent across the United States, Canada, Australia, and Argentina, this creates a genuinely broad eligibility pool. The key challenge is proving that each person in the descent chain held Polish citizenship and did not renounce it under the laws of the time.

Processing runs between eight and eighteen months with no language test required. The resulting passport carries full EU rights and visa-free access to over 180 countries. Genealogical research for a Polish claim can be substantial, and specialist legal assistance is strongly advisable for families whose ancestry extends more than two generations.

Germany: The Restitution Route and the 2024 Reform

Germany’s standard citizenship by descent program applies primarily to descendants of German citizens through the parent generation. The more widely applicable route is the restitution pathway under Article 116 of the Basic Law.

Descendants of people who were persecuted and stripped of their German citizenship between 1933 and 1945 are entitled to reclaim it as a matter of restitution. This pathway has no generational limit and has been accessed by tens of thousands of descendants across the world.

Germany’s June 2024 nationality law reform now permits dual citizenship for naturalisation cases, removing the long-standing requirement that most applicants renounce their existing passport. The German passport offers visa-free access to over 190 countries.

The Documents That Make or Break the Application

Every ancestry citizenship application rests on a chain of documentation. Birth certificates, marriage certificates, and death certificates for every person in the direct line of descent are the foundation.

Where an ancestor naturalised as a citizen of another country, the naturalisation certificate and its date are critical. The date of naturalisation relative to the birth of the next generation determines whether citizenship was passed on before it was lost.

Specialist firms in every major market focus specifically on citizenship by descent documentation and application processing. Their cost is a fraction of what citizenship by investment programs charge for a comparable outcome.

An Honest Assessment of the Timeline and the Stakes

Citizenship by descent is not a fast route. Processing times across all four major programs currently run between one and four years depending on the country, the consulate, and the complexity of the individual case.

For those planning for the generation that follows theirs, the case for ancestry citizenship is difficult to argue against. Irish citizenship obtained this year passes to your children. Italian citizenship obtained this year passes to your children under current rules.

The rule changes of 2025 and 2026 are a reminder that these windows are not permanent. Spain’s Democratic Memory Law closed at the end of October 2025 and is no longer accepting new applications. The family tree that most people have never examined seriously may contain an entitlement more valuable than any investment program currently on the market.

Key Takeaways (FAQs)

What is citizenship by descent?
Legal recognition, known as jure sanguinis, that citizenship is a heritable right passed from parent to child across generations — no investment, minimum stay, or in most cases language test required.

Which grandparent qualifies you for Irish citizenship?
Any grandparent born on the island of Ireland entitles you to register through the Foreign Births Register, with no language test or residency requirement.

Has Italy’s ancestry citizenship program changed?
Yes. Decree-Law No. 36 of March 2025, upheld by Italy’s Constitutional Court in March 2026, now generally limits new applications to descendants of Italian parents or grandparents, ending the previous unlimited-generation window.

Does Poland have a generational limit on citizenship by descent?
No. Any descendant of a person who held Polish citizenship after 1920 may be eligible, provided the chain was never broken by renunciation.

What is Germany’s restitution pathway?
Under Article 116 of the Basic Law, descendants of people persecuted and stripped of German citizenship between 1933 and 1945 can reclaim it, with no generational limit.

Can you pass Irish or Italian citizenship to your children?
Yes, under current rules — Irish citizenship obtained this year passes to your children, as does Italian citizenship obtained under the post-2025 framework.

How long does citizenship by descent processing take?
Between one and four years across the four major programs, depending on the country, consulate, and complexity of the individual case.

Are ancestry citizenship windows permanent?
No. Spain’s Democratic Memory Law closed to new applications at the end of October 2025, and Italy’s 2025 reform shows these pathways can be narrowed with little warning.
