Citizenship by descent—often called “citizenship through ancestry”—offers a low‑cost route to a second passport, but many applicants stop at parents or grandparents and miss opportunities that extend further back. Several European nations allow claims that reach great‑grandparents or even earlier generations, provided the necessary documentation can be produced.
Countries that permit extended ancestry claims
| Country | Generational limit | Approx. eligible diaspora | Key benefits / notes |
|---|---|---|---|
| Ireland | Up to great‑grandparents (third generation) if the ancestor was registered in the Foreign Birth Register. | ~4 million Irish citizens abroad; roughly four times as many passports issued. | Full EU citizenship; right to live and work in the EU and, under the pre‑Brexit Common Travel Area, in the UK. |
| Italy | No fixed generational cap; claims can reach great‑grandparents and beyond as long as the ancestor was an Italian citizen before the family emigrated. | 83–85 million people worldwide potentially eligible, with large communities in the U.S., Canada, Brazil, Uruguay, and other Latin American nations. | EU citizenship; strong global diaspora makes documentation often accessible. |
| Poland | No generational limit after the establishment of the Second Polish Republic (1918). | 30 million+ people of Polish ancestry worldwide; 10–20 million in North America. | EU passport; recent visa‑free access to the United States enhances travel value. |
| Hungary | Claims can extend to great‑grandparents and further for ethnic Hungarians. | Over 1 million approvals since the law opened about a dozen years ago. | EU citizenship; however, Hungarian passports are not covered by the U.S. Visa Waiver Program, requiring a visa for U.S. travel. |
| Bulgaria | No explicit generational limit for ethnic Bulgarians. | Significant ethnic Bulgarian communities in Serbia, Macedonia, and other Balkan states. | EU citizenship; Bulgaria does not have a U.S. Visa Waiver agreement, so a U.S. visa is still required. |
| Slovakia | Recently expanded to allow great‑grandparent (and potentially earlier) claims. | Smaller diaspora than Italy or Poland, but still sizable in neighboring Balkan countries. | EU passport with broad travel freedom, including the United States. |
| Latvia | No generational cap if ancestors were expelled due to war or are of Latvian ethnicity. | Relatively modest diaspora; many claimants have mixed Latvian/Lithuanian heritage. | EU citizenship; careful genealogical research needed to avoid confusion with neighboring ethnicities. |
| Lithuania | Claims can reach great‑grandparents who were citizens of the Republic of Lithuania (1918‑1940) or who left before 1990. | Moderate diaspora, especially in the U.S. and Canada. | EU passport; some restrictions on dual citizenship may require renunciation of the original nationality. |
| Luxembourg | Generally limited to grandparents (second generation), but paternal lines may allow great‑grandparent claims. | Estimated five‑figure to low six‑figure diaspora worldwide. | EU citizenship; strict documentation standards, but a valuable passport for global mobility. |
Practical steps and common hurdles
- Documentary proof is essential – DNA tests are not accepted. Applicants must gather birth, marriage, death, and naturalisation certificates that trace the lineage from the ancestor to the applicant.
- Archive research – Often the required records are held in local civil registries, parish archives, or national archives. This may involve travel to the ancestor’s hometown or hiring a local researcher.
- Chain continuity – The lineage must be uninterrupted. A break—such as a naturalisation before the birth of the next generation—can disqualify the claim (e.g., Italy’s “jure sanguinis” rule).
- Application channels – Depending on the country, the process may be handled through an embassy, a consular office, or a domestic court. After the documents are verified, the passport is issued.
- Timing – While the documentation phase can take months or years, the actual processing after submission is usually a waiting period.
Why consider these passports?
- Travel freedom – Most of the listed EU passports grant visa‑free or visa‑on‑arrival access to the United States, Canada, the Schengen Area, and many other destinations.
- Residency and work rights – Holders can live, work, study, or start a business anywhere in the European Union, and in Ireland’s case, also in the United Kingdom under the Common Travel Area.
- Tax planning – Some jurisdictions offer favorable tax regimes for non‑resident citizens, though this varies and may be affected by bilateral tax treaties.
Decision criteria
- Ancestral documentation – Choose a program where the required records are most likely to be available (e.g., large diaspora communities often have better‑preserved archives).
- Travel needs – If U.S. visa‑free travel is a priority, prioritize Ireland, Italy, Poland, Slovakia, Latvia, Lithuania, or Luxembourg over Hungary or Bulgaria.
- Dual‑citizenship rules – Verify whether the target country permits dual nationality; some, like Lithuania, may require renunciation of the original citizenship for descent‑based applicants.
- Processing time and cost – While the application fee is usually modest, the cost of obtaining documents and possible legal assistance can be significant.
In summary, nine European nations—Ireland, Italy, Poland, Hungary, Bulgaria, Slovakia, Latvia, Lithuania, and Luxembourg—offer citizenship by descent that can extend beyond grandparents. Successful applicants must assemble a complete paper trail of their ancestry, navigate each country’s specific legal requirements, and consider the passport’s travel and residency advantages against any dual‑citizenship restrictions. Checking a family tree beyond the immediate two generations can reveal eligibility for a valuable, often cost‑free, second passport.
