Citizenship by Descent: How to Claim an EU Passport Through Ancestry (Italy, Ireland, Poland)

If your great-grandmother sailed from Naples, your grandfather was born in County Cork, or your family name traces back to a village near Krakow, you may already hold a legal right to an EU passport. You just have not claimed it yet. Citizenship by descent, also called citizenship by ancestry or jure sanguinis (“by right of blood”), lets the descendants of emigrants reclaim the nationality their ancestors carried with them. It is the quiet alternative to the golden visa: instead of investing several hundred thousand euros, you assemble a paper trail. Done right, it can cost a few thousand euros in fees and translations rather than a six-figure investment.

The catch is that the rules tightened sharply in 2025 and 2026, especially in Italy, and the paperwork is unforgiving. This guide walks through the three pathways Americans, Britons, Australians, and others ask about most: Italy, Ireland, and Poland. It is built from official sources and current 2026 figures. It is general information, not legal advice on your specific family tree.

Why Descent Beats a Golden Visa (When You Qualify)

A golden visa or citizenship-by-investment program asks for money: a property purchase, a fund subscription, or a government donation, often in the range of 250,000 to 1,000,000 euros depending on the country. Citizenship by descent asks for proof instead. If you can document an unbroken chain of nationality from a qualifying ancestor down to you, several EU states will recognize that you were a citizen all along.

The payoff is identical at the finish line. An Italian, Irish, or Polish passport is an EU passport, which grants the right to live, work, study, and retire in any of the 27 EU member states, plus visa-free or visa-on-arrival access to roughly 190 destinations. The difference is the entry ticket. Descent is far cheaper, but it is gated entirely by your bloodline and your documents. No amount of money fixes a missing birth certificate or an ancestor who naturalized at the wrong moment.

One more honest caveat. Descent claims reward patience and precision. Timelines run from several months to several years, archives lose records, and a single mismatched spelling on a 1910 ship manifest can stall a file. This is where professional help earns its fee.

Italy: The Door Narrowed in 2025

Italy was for decades the most generous descent pathway in Europe. There was no generational limit, so people claimed citizenship through great-grandparents and even great-great-grandparents. That era ended on March 28, 2025, when the Italian government issued Decree-Law 36/2025, converted into Law No. 74/2025 on May 24, 2025. Italy’s Constitutional Court upheld the new caps on March 12, 2026, so the tightening is now settled law.

Here is what changed. A person born abroad who holds another citizenship is now generally deemed to have never acquired Italian citizenship, with three narrow exceptions:

1. A recognition application (or confirmed consular appointment) was submitted before 11:59 p.m. Rome time on March 27, 2025. These “grandfathered” files, roughly 60,000 of them, are still judged under the old, unlimited rules.
2. A parent or grandparent held exclusively Italian citizenship at the time of their death, meaning they never naturalized elsewhere.
3. A parent resided in Italy for at least two consecutive years after acquiring citizenship and before the applicant was born.

In plain terms, the practical reach is now roughly two generations. You generally need an Italian-born parent or grandparent, and the “exclusivity” rule matters enormously: if your Italian ancestor became a US, British, or Australian citizen, that naturalization can break the chain for descendants born abroad. The estimated 80 million people of Italian descent worldwide just saw the eligible pool shrink dramatically.

A few wrinkles remain in play in 2026. The so-called “1948 cases,” where citizenship passed through a female ancestor before January 1, 1948, still require a court petition in Rome rather than a consular application, because Italy did not let women transmit citizenship before that date. The Italian Supreme Court was also reviewing a separate “minor issue” in 2026 that affects whether an ancestor’s naturalization while a child was minor broke the line. If your case touches either, get specialist advice before spending on documents.

Ireland: The Grandparent Rule Stays Generous

Ireland is now the most welcoming of the three for people one or two generations removed, and it did not tighten in 2025 or 2026. Citizenship flows through the Foreign Births Register (FBR), governed by the Irish Nationality and Citizenship Act 1956.

The core rule is simple. If you have at least one grandparent who was born on the island of Ireland, you are entitled to Irish citizenship even if neither of your parents was born there. You register your birth on the FBR, and you become an Irish citizen from the date of entry on the register, not from birth.

The great-grandparent question is where people get tripped up. You can claim through a great-grandparent, but only if your parent had already registered on the Foreign Births Register before you were born. Citizenship does not skip a generation automatically. Each generation past the Irish-born grandparent must have been registered in time. If your parent never registered, the line stops at you.

Demand has surged. Brexit drove a wave of UK applicants, and American interest has climbed steadily, prompting the Department of Foreign Affairs to stand up a dedicated FBR team. As of 2026, processing runs roughly 9 to 12 months. Fees are modest: about 278 euros for an adult and 153 euros for a minor. Documents must be originals, long-form state-issued certificates. Photocopies and decorative “commemorative” certificates are rejected outright.

Poland: Continuity Is Everything

Polish citizenship by descent is technically a “confirmation” of citizenship rather than a grant. The legal theory is that if your ancestor was a Polish citizen and never lost that status, citizenship passed down the line to you automatically, and the state simply confirms it. There is no fixed generational limit, which means well-documented claims can reach great-grandparents or further.

The pivotal date is January 31, 1920, when Poland’s first modern citizenship law took effect after the country regained independence. Ancestors who lived in Poland on or after that date and did not lose their citizenship are the strongest cases. If your ancestor emigrated before 1920, the claim is not automatically dead, but the burden shifts to you to show they were still treated as Polish citizens afterward, through consular registrations, passport records, or correspondence with Polish authorities.

Continuity is the whole game. Several historical traps can sever a Polish citizenship line: serving in a foreign army, accepting certain foreign public offices, or, in some periods, naturalizing abroad before specific dates. Men of military-service age in certain years are a classic complication. Because the rules changed across the interwar, wartime, and communist eras, Polish cases reward genealogical detective work more than any other pathway here.

Applications go to a provincial governor (wojewoda) for residents of Poland, or through a Polish consulate for applicants abroad. Expect to supply civil records, church-book extracts, military books, and archival certificates, many of which must be tracked down in Polish state and ecclesiastical archives.

Side-by-Side: The 2026 Snapshot

Factor	Italy (post-reform)	Ireland	Poland
Core qualifying ancestor	Parent or grandparent (with exclusivity/residence conditions)	Grandparent born in Ireland	Ancestor who was Polish citizen, esp. on/after 31 Jan 1920
Generational reach	~2 generations now (was unlimited pre-2025)	Grandparent freely; great-grandparent only if parent pre-registered	No fixed limit if continuity is proven
Key cutoff or rule	Mar 27, 2025 deadline for old rules; “exclusive citizenship at death” test	Each generation must register on FBR before next is born	Jan 31, 1920 citizenship law; no loss of citizenship
Where you apply	Consulate, comune, or Rome court (1948 cases)	Foreign Births Register (DFA)	Wojewoda (in Poland) or consulate (abroad)
Government fee (2026)	Varies; ~600 euros court fee per petitioner in 1948 cases	~278 euros adult / ~153 euros minor	Several hundred euros plus archival costs
Typical timeline	Consular months to years; court cases 18 to 36 months	~9 to 12 months	Often 1 to 3 years, document-dependent

Figures are approximate 2026 government and reputable-source estimates and exclude legal fees, translations, and document procurement, which commonly add 1,000 to several thousand euros per family.

What Every Application Needs

Three documents form the spine of almost every descent claim: the qualifying ancestor’s birth record, marriage records linking each generation, and your own birth certificate, plus equivalents for everyone in between. From there, the universal rules apply.

Originals only. Most authorities want recently issued, long-form, state-certified civil records, not photocopies and not heirloom certificates. Apostilles matter. Documents issued abroad usually need an apostille under the Hague Convention to be accepted, and certified translations into Italian or Polish are mandatory for those two countries. Names must match. The single most common reason files stall is inconsistent spelling across generations, a “Giovanni” who became “John,” a surname respelled at Ellis Island. Naturalization timing is decisive. For Italy and Poland in particular, when and whether your ancestor naturalized abroad can make or break the claim, so order the ancestor’s full naturalization record (or proof they never naturalized) early.

Should You Start With Descent or an Investment Route?

If you have a credible ancestral line into Italy, Ireland, or Poland, descent is almost always the better first thing to investigate. It is cheaper by an order of magnitude and ends in full citizenship rather than temporary residence. The honest reasons to look at a residency or investment program instead are time and eligibility. If your ancestor naturalized at the wrong moment, if records were destroyed, or if you need an EU base within months rather than years, a golden visa may be the realistic path. Many families pursue both: a descent claim for the long game, a residency route for the near term.

Get Your Family Line Assessed Before You Spend

Descent claims succeed or fail on details that are invisible until an expert reads your specific family tree against current law: an ancestor’s naturalization date, a missing marriage record, the exact wording of a 2025 Italian exception. Before you pay for apostilles and certified translations on a file that may not qualify, it is worth a professional eligibility review. CIVITAS provides independent, confidential assessments of ancestry and investment-based pathways across the EU and can tell you, honestly, whether your line holds and which country gives you the strongest claim.
