Polish citizenship by descent · Confirmation of citizenship

You may already be a Polish citizen.

Polish citizenship passes by blood, parent to child, and leaving Poland did not erase it. If a parent, grandparent, or great-grandparent was a Polish citizen, Poland may simply need to confirm what is already yours: EU citizenship, with the right to live, work, and study across all 27 EU countries. We check your line, tell you straight, then run the whole case.

Who qualifies

If Poland is one, two, or three generations back, the door may be open.

Around ten million Americans have Polish roots. Polish citizenship passes by descent, parent to child, no matter where each generation was born. A grandparent or great-grandparent who was a Polish citizen is the line most families check first. You don't have to figure out where your case fits. That's our job.

★ Most common path · Grandparent and beyond

Through your grandparent or great-grandparent

Confirmation of citizenship · administrative, no court

If a grandparent or great-grandparent was a Polish citizen and the line runs straight down to you, parent to child, Polish citizenship may have reached you at birth, even though you were born in the United States. The further back the line starts, the more the family history matters, and that is exactly what we check.

  • Grandparent or great-grandparent who held Polish citizenship
  • Administrative confirmation, prepared and filed by our team
  • Entirely remote, we act under power of attorney
  • No residency, no language test, no oath, no travel
  • Left before 1920 or unsure of the dates? Still worth checking

Strongest line · Likely already a citizen

Through your parent, a Polish citizen

Citizen from birth · confirmation puts it on paper

If your parent held Polish citizenship when you were born, you are very likely a Polish citizen already, from the day you were born. Confirmation is the formal decision that documents it, and it opens the way to a Polish passport.

  • Parent who was a Polish citizen when you were born
  • Citizen from birth, the decision simply confirms it

The rules, plainly

How Polish citizenship by descent
actually works.

Poland's citizenship law goes back to the Citizenship Act of 1920, passed just after the country regained independence. From then on, Polish citizenship has passed by blood, parent to child, generation after generation. Emigrating to America did not erase it, and being born in the United States does not block it.

That is why the procedure is called confirmation of citizenship. You are not applying to become Polish. A Polish provincial office reviews the family documents and confirms the citizenship you have held since birth. No residency. No language test. No oath. No trip to Poland. We act for you under power of attorney.

Two dates do most of the deciding: 1920, when the citizenship law took effect, and January 19, 1951, when an older set of rules on foreign naturalization and on how citizenship passed within a family ended. What happened around those dates shapes each case. We read them first, and tell you straight.

Information current as of July 2026. Updated when the rules change.

What decides a confirmation case

1
A Polish citizen in your direct line
A parent, grandparent, or great-grandparent who held Polish citizenship
2
An unbroken chain, parent to child
Citizenship must pass down the direct line, one generation at a time
3
What happened before the key dates
Departure before 1920 and events before January 19, 1951 can shape the case, so we check them first

A confirmation of what you already hold, not naturalization. No court, no trip to Poland. We run it end to end.

Why Polonia Citizenship

Run by people who have done this a thousand times.

🧭
We classify the case, you don't have to

Most people we hear from aren't sure whether a grandparent or great-grandparent line qualifies, or what a 1930s naturalization did to it. That's fine. Tell us a few family facts; we'll read your line against Polish law and tell you which route is yours, or that none is. No self-diagnosis required.

We say no when it's no

If you qualify, we'll say so. If the line is broken, we'll tell you that clearly and explain what, if anything, might still be open, like a document from the Polish archives that changes the picture. No false hope.

Common questions

Straight answers

My grandparent left Poland decades ago and never went back. Can I really be a citizen?+

Quite possibly. Polish citizenship passes by blood, parent to child, and leaving Poland did not take it away by itself. What matters is when your ancestor left and what happened afterward, like the date of any foreign naturalization.

Tell us the family story and we'll read your line against Polish law, then reply with a straight answer.

What about a great-grandparent?+

A great-grandparent line can absolutely work. Citizenship has to pass through every generation in between, so the further back the line starts, the more the dates and events along the way matter, especially anything before January 19, 1951.

Tell us what you know and we'll tell you straight whether the line holds, before you spend anything.

My family left before 1920. Is that the end of it?+

Not always. Poland regained independence in 1918 and its citizenship law took effect in 1920, so ancestors who left earlier emigrated as subjects of the partitioning empires, not as Polish citizens. That usually closes the standard route.

There is a real exception: any document issued to your ancestor by Polish authorities after 1920, such as a Polish passport, a consular registration, or a Polish civil record, can reopen the case. If anything like that exists in the family papers, it's worth checking before assuming no.

My ancestor became a US citizen. Doesn't that break the line?+

It depends entirely on the date. A foreign naturalization before January 19, 1951 generally ended Polish citizenship and can break the chain. After that date, taking US citizenship did not, by itself, cause any loss.

A common myth says any US naturalization closes the case. It doesn't. The date decides, and it's one of the first things we check.

Do I have to travel to Poland, live there, or speak Polish?+

No. Confirmation of citizenship is an administrative process, and we run it in Poland on your behalf under power of attorney. No residency, no language test, no oath, no consular interview.

You sign the papers at home and we handle the rest, through to the decision.

Can I keep my US citizenship?+

Yes. The confirmation procedure recognizes citizenship you already hold, so there is no oath and nothing to renounce. Your US citizenship stays exactly as it is.

We have no Polish documents at all. Is that a dealbreaker?+

No. Missing papers never end a case by themselves. Polish civil records, church books, military files, and residency registers survive in regional archives, and searching them is part of our work.

What helps most is your ancestor's town of birth in Poland and their parents' names. Even partial information gives the search a starting point.

Who actually handles my case?+

We do, the Polonia Citizenship team at Five to Europe, with more than ten years of Polish citizenship work behind us. From your eligibility read through the archival research, preparing the application, filing it under power of attorney, and following it to the decision.

One point of contact, one process, start to finish.

What happens to my information after I submit?+

We read it. We do not sell it or use it for ad retargeting. If you'd prefer we delete your submission after replying, say so in your message and we will.
