EU Citizenship by Descent — The Complete Guide for American Families

Tens of millions of Americans have a legitimate path to EU citizenship through their ancestry. Most of them have never applied — not because they don't qualify, but because the process seemed too complex, too expensive, or too uncertain to pursue.

This guide covers everything you need to know: which countries offer citizenship by descent to Americans, who qualifies, what it actually gives you, and how to find out whether your family's path is open.

What EU citizenship by descent means

Citizenship by descent — sometimes called jus sanguinis, or right of blood — is the legal principle that citizenship passes from parent to child regardless of where the child is born. Most European countries use this as their primary citizenship framework.

For Americans with European ancestry, this means that citizenship may have been passing through your family line for generations — potentially without anyone knowing or acting on it. Confirming that citizenship is a matter of documentation, not a new application. The practical result is full EU citizenship: the right to live, work, and study in any of the 27 EU member states, an EU passport with visa-free access to approximately 190 countries, and the right to pass that citizenship to your own children at birth.

Ireland: the most accessible path for grandchildren

If one of your parents was born in Ireland and was an Irish citizen when you were born, you are automatically an Irish citizen by birth — no registration needed, simply apply for an Irish passport.

If one of your grandparents was born in Ireland, you can register in the Foreign Births Register and become an Irish citizen. Your grandparent must have been an Irish citizen when your parent was born. Ireland includes Northern Ireland — it counts equally with the Republic. The application fee is €278 for adults, processing takes approximately 9 months, and applications are submitted online through dfa.ie. Ireland has always allowed dual citizenship.

One important note: if your parent was not born in Ireland and has not already registered their Irish citizenship, your parent needs to register first. The registration chain must be maintained for each generation.

Italy: parent or grandparent qualifies under current rules

Italian citizenship by descent went through a significant reform in 2025. Under Law 74/2025, upheld by Italy's Constitutional Court on March 12, 2026, new applications for Italian citizenship by descent are limited to people with a parent or grandparent born in Italy who held exclusively Italian citizenship at the relevant time.

Applications filed on or before March 27, 2025 are processed under the previous rules, which had no generation limit.

Three additional paths remain available regardless of the 2025 reform: the judicial pathway for pre-1948 maternal lines (completely unaffected), two-year Italian residency (no generation limit), and reacquisition for certain pre-1992 citizenship losses.

Italy allows dual citizenship. Consulates currently have significant wait times — booking early is recommended. Fee: €600 per adult.

Germany: citizenship passes through parents automatically

If one of your parents was a German citizen when you were born, you acquired German citizenship automatically at birth. The complexity is in determining whether your parent actually held German citizenship — particularly if your parent naturalized as a US citizen before June 27, 2024 and did not hold a retention permit.

Germany legalized dual citizenship on June 27, 2024. German citizenship cannot skip a generation — you cannot inherit it directly from a grandparent if your parent never held it. A separate pathway under Article 116(2) covers all descendants of Nazi persecution victims with no generation limit. No language test, no residency requirement.

Poland: no generation limit, but check the 1920–1951 window

Polish citizenship by descent has no generation limit. Any generation can potentially qualify, provided the citizenship chain was never broken.

The most common chain-breaker: Polish ancestors who naturalized as US citizens between 1920 and 1951 automatically lost Polish citizenship at that moment. The first step for any Polish case is finding the ancestor's US naturalization records at archives.gov.

Poland allows dual citizenship. The application fee is approximately $15 USD. Processing takes 12 to 16 months.

What EU citizenship actually gives your family

• Freedom of movement: live, work, and study in any of the 27 EU member states without visas or work permits.

• Education: EU citizens pay domestic tuition rates at European universities — often zero to a few thousand euros per year at public universities. A four-year European degree frequently costs less than a single year at a US university.

• Travel: An EU passport provides visa-free or visa-on-arrival access to approximately 190 countries.

• Generational transfer: children born to EU citizens acquire citizenship automatically at birth, regardless of where they are born.

• Dual citizenship: all four countries — Ireland, Italy, Germany, and Poland — allow dual citizenship. You keep your US passport.

Common questions

Do I have to move to Europe? No. None of the four countries require residency to confirm citizenship by descent.

Do I have to speak the language? No. None of the four countries require language proficiency for citizenship by descent claims.

Does this affect my US citizenship? No. You hold both passports.

How long does it take? Ireland: ~9 months. Italy: 1–3+ years depending on consulate. Germany: 6–18 months. Poland: ~12–16 months.

The legacy question

The deeper reason most families pursue EU citizenship is about identity, heritage, and what you pass to your children. Your great-grandparents crossed an ocean to build something. EU citizenship by descent is the acknowledgment that what they left behind still belongs to your family. An EU passport in your child's hands is a door they can open for the rest of their life — to live, to work, to study, to retire, across one of the most prosperous regions in the world.

For parents: the citizenship you confirm today becomes your children's birthright. That is something real to pass down.
