Polish citizenship by descent: who is eligible

If a parent, grandparent or earlier ancestor held Polish citizenship, you may already be a Polish citizen. You don’t apply for new citizenship. You ask the Polish authorities to confirm the citizenship you inherited, which then lets you apply for a Polish passport and live, work and study anywhere in the EU.

Polish ancestry on its own is not enough. What matters is whether your ancestor was a Polish citizen and whether that citizenship passed down the line without being lost. That is why we start every case with a free eligibility assessment.

The three conditions for citizenship by descent

1. A direct ancestor held Polish citizenship. In most cases this means they were a permanent resident of Poland, or its former territories, on or after 31 January 1920, when Poland’s first citizenship law took effect.
2. The citizenship was never lost. Before 1951, Polish citizenship could be lost by becoming a citizen of another country, holding public office or serving in a foreign army. Women could also lose it by marrying a non-Polish citizen. Each generation needs checking.
3. It passed to each generation in turn. Citizenship passes from parent to child. There’s no fixed limit on generations, as long as each person in the line, from your Polish ancestor down to you, kept their citizenship.

What if my ancestor left Poland before 1920?

Emigration before 1920 is the most common complication, because Poland did not exist as an independent state before 1918. Some of these cases can still succeed, depending on records from the period and the family’s circumstances. They need careful assessment, and they are the kind of complex case we specialise in.

Documents you will need

• Birth and marriage certificates for each generation back to your Polish ancestor
• Evidence your ancestor held Polish citizenship, such as a Polish passport, ID, military or residence records
• Naturalisation records from the country your ancestor moved to, if any
• Sworn Polish translations of all foreign documents

We locate archive records in Poland and abroad, and our team of sworn translators handles official translations required by the Polish government.

If you don’t qualify by descent

• Presidential grant. The President of Poland can grant citizenship to people with a strong connection to Poland who don’t meet the descent rules. Decisions are discretionary. Read our presidential grant guide.
• Karta Polaka. The Pole’s Card confirms Polish heritage for people who can show Polish nationality in their family and speak basic Polish. It does not grant citizenship, but holders can apply for permanent residence in Poland, a route that can later lead to citizenship. Is Karta Polaka for you?

How long does it take?

Timeframes vary and change often, so we’ll give you an up-to-date estimate as part of your free eligibility assessment. Gathering archive documents can add time, particularly for pre-1920 and Jewish heritage cases.

Frequently asked questions

Do I need to speak Polish?

No. There is no language requirement to confirm citizenship by descent.

Can I keep my current citizenship?

Poland does not require you to give up your other citizenship. Check your own country’s rules too.

Can I qualify through a great-grandparent?

Often, yes, if each generation kept their citizenship.

My ancestor served in the US army. Does that matter?

It can. Military service in a foreign army before 1951 sometimes caused loss of citizenship. We check this in every assessment.

Do I have to live in Poland?

No.
