Yes. You can be Polish and American at the same time, and neither country will make you give the other up. Polish law has no ban on a second citizenship, and a Pole can lose Polish citizenship only by renouncing it. That applies to Poles who naturalise in the US and to descendants who confirm Polish citizenship by descent. The catch is Article 3 of the Citizenship Act: Poland doesn’t really recognise your second citizenship. In its dealings with you, you are only Polish, which matters most at the border.

The short answer

  • Pole who becomes American today: stays Polish. There’s no permission to get and nothing to file.
  • American confirming Polish citizenship by descent: keeps US citizenship. Giving it up isn’t a condition.
  • In Poland: you are treated only as a Polish citizen, so travel on a valid Polish document.
  • Your ancestors: older laws could end citizenship, so check each generation against the rule in force at the time.
  • The only way to lose it now: renunciation, with the President’s consent.

What Article 3 actually says

The Act of 2 April 2009 on Polish Citizenship doesn’t say “dual citizenship is allowed”. Article 3 takes it as a given and limits what it means. In our translation:

  1. A Polish citizen who also holds the citizenship of another state has the same rights and duties towards the Republic of Poland as a person holding Polish citizenship only.
  2. A Polish citizen may not, with legal effect, rely on the other citizenship, or on rights and duties flowing from it, before the authorities of the Republic of Poland.

So a second citizenship doesn’t excuse you from any duty Polish law places on citizens, and it gives you no special standing with Polish officials. Your US passport has no legal weight for them if you are Polish.

Crossing the Polish border

This is where Article 3 bites. Poland’s Powroty portal, citing the Border Guard, said in 2021 that a dual citizen relying on Polish citizenship at passport control should show a valid Polish travel document, and that a foreign passport alone isn’t enough.

  • Entering on a foreign passport: you may be treated as a third-country national, limited to 90 days in any 180, with sanctions for overstaying.
  • Leaving: if the officer establishes that you are also Polish, you are treated only as a Polish citizen. Overstay sanctions can’t apply, but you are still expected to show a valid Polish document.
  • The dispute: in July 2023 the Border Guard’s commander told the Ombudsman that officers must refuse to let a Polish citizen without a valid Polish document cross the border. The Ombudsman argued that citizenship law doesn’t support this, that holding a passport is a right rather than a duty, and that EU free movement law points the other way. We found no later published resolution.

The safe course is simple: once you are a confirmed Polish citizen, get a Polish passport and use it for Poland. You’ll still need your US passport for the United States. Powroty notes that its article is information, not a binding reading of the law.

How Polish law moved from one citizenship to tolerating two

Poland has had four main citizenship acts. Each one treats a second citizenship differently, and each one applies to the people who lived under it. These points come from the acts as published.

1920 to 1951: acquiring a foreign citizenship ended Polish citizenship

  • Article 11 of the Act of 20 January 1920 ended citizenship on acquiring a foreign one, or on taking public office or joining the military of a foreign state without the Polish government’s consent.
  • The military exception. The same article says people obliged to do active military service could acquire a foreign citizenship only with the Military Minister’s permission. Without it, the Polish state would go on treating them as citizens. The article gives no age range, so the man’s actual liability at the time is what needs proving.
  • Article 13 extended a man’s loss to his wife and to children up to 18, unless the Interior Minister decided otherwise.
  • Married women and children. Children born in wedlock took their father’s citizenship and children born out of wedlock their mother’s (Article 5). Article 10 shows that a Polish woman could lose citizenship by marrying a foreigner.

1951 to 1962: permission required

The Act of 8 January 1951 declared that a Polish citizen couldn’t also be a citizen of another state (Article 1). A Pole could acquire a foreign citizenship only with the permission of the Polish authorities, and doing so with that permission ended Polish citizenship (Article 11). Someone who naturalised abroad without permission wasn’t covered by that loss. But the state could now strip citizenship from people abroad for reasons including disloyalty, illegal departure after 9 May 1945, refusing to return or evading military service (Article 12).

Article 4 also excluded some people who held Polish citizenship on 31 August 1939 and lived permanently abroad: those who took another state’s citizenship by treaty after the border changes, and those of Russian, Belarusian, Ukrainian, Lithuanian, Latvian, Estonian or, with one exception, German nationality.

1962 to 2012: the same idea, softer wording

The Act of 15 February 1962 said a Polish citizen couldn’t, under Polish law, also be recognised as a citizen of another state (Article 2). Change of citizenship still needed permission, and the permitted change ended Polish citizenship (Article 13). A woman who got a foreign citizenship through marriage could give up Polish citizenship by declaration (Article 14), and citizens abroad could still be stripped of it (Article 15).

Since 1997 and 2012: only you can end it

Article 34(2) of the 1997 Constitution says a Polish citizen can’t lose Polish citizenship unless they renounce it. The 2009 Act, in force since 15 August 2012, follows that. Article 46 makes renunciation with the President’s consent the only ground for loss, and Article 5 confirms that marrying a foreigner changes nothing.

What descendants claiming by descent need to know

Under Article 14 a child with at least one Polish parent is Polish by birth, and Article 2 keeps as citizens those who held citizenship under earlier law. There’s no generation limit in the Act. So a descendant isn’t applying to become Polish. You are asking a voivode to confirm you already are, which means the line has to hold through each period:

  1. Was the ancestor Polish at all? The 1920 Act defined the first citizens by their links to the new state’s territory. An ancestor with a foreign citizenship by then wasn’t included, which is why the 1920 starting point is the first thing to prove.
  2. A naturalisation before 19 January 1951? That’s when the 1951 Act took effect. Check for Article 11 of the 1920 Act, and the military exception if he was a man liable for service.
  3. A naturalisation between 1951 and 1999? Don’t assume it was harmless. Look for a permission to change citizenship, or a deprivation order. As we read the 1951 and 1962 Acts, a naturalisation abroad without permission didn’t end Polish citizenship, but the voivode decides, so don’t treat that as settled for your family.
  4. A woman or a mixed marriage in the line? Check marriage dates against the 1920 Act. From 1951 a child with one Polish and one foreign parent was Polish if born in Poland, but one born abroad only in the reciprocal cases in Article 9. The 1962 Act made such children Polish by birth wherever they were born, though parents could choose the foreign citizenship within three months (Article 6).

How to file is covered in our guides to Polish citizenship confirmation and the Polish passport by descent.

If someone in your family lost it: restoration

Article 38 lets a foreigner who lost citizenship before 1 January 1999 have it restored, if the loss came under Article 11 or 13 of the 1920 Act, Article 11 or 12 of the 1951 Act, or Article 13, 14 or 15 of the 1962 Act. The Interior Minister decides. It’s refused to anyone who voluntarily served the Axis forces or took public office for the Axis between 1 September 1939 and 8 May 1945, who acted against Poland or took part in human rights abuses, or whose return would threaten security.

Two limits matter for families. The application is made by the person who lost citizenship, and it takes effect only on the day the decision becomes final (Article 39), so it doesn’t make a child born earlier Polish. Polish missions in the US list a fee of 59 USD.

Your other citizenship

Poland’s rules don’t bind other countries. For Americans, the State Department’s Foreign Affairs Manual says US citizens who naturalise elsewhere don’t automatically lose US citizenship and that an intent to keep it is presumed, and under 8 U.S.C. 1481 it’s lost only by a voluntary act meant to give it up. Confirmation isn’t even a naturalisation, since it recognises existing status. The manual adds that the US doesn’t encourage dual nationality and that the other country has a predominant claim on you while you’re there, which matches Article 3 from the US side. You must use a US passport to enter and leave the United States.

More on this is in European citizenship by descent for Americans. If your line fails, recognition under Article 30 doesn’t list giving up another citizenship as a condition either. It needs residence in Poland and B1 Polish, and people with a permanent residence permit based on Polish origin or a Karta Polaka can qualify after one year.

Giving up Polish citizenship

You can’t simply declare it. Under Articles 46 to 51 you ask the President for consent, through a voivode or a consul, with proof that you hold another citizenship or have been promised one. The President may agree or refuse, and citizenship ends 30 days after the decision unless it sets an earlier date. In Poland the fee is 1,669 zł; Polish missions in the US list 529 USD.

Practical steps

  1. Map every generation. Note births, marriages, naturalisations and any military service. The USCIS naturalisation records guide shows how to find US dates, and the document chain guide covers the rest.
  2. File for confirmation. It goes to the voivode for your current or last address in Poland or, with none, the Mazovian Voivode (Article 55). From abroad you can file through your consul. The Interior Ministry lists 277 zł for the decision; if you file at a consulate you pay the consular fee, which Polish missions in the US list as 118 USD. Foreign documents need a sworn Polish translation (Article 12), and each minor child needs a separate application.
  3. Allow time. The voivode has six months, but waits for records and other offices don’t count towards that, and it can be extended. An appeal must be filed within 14 days.
  4. Get your Polish passport before you next travel to Poland. Polish missions say a valid passport or ID card is the document that proves citizenship.

Frequently asked questions

Does Poland allow dual citizenship with the USA?

Yes, you can be Polish and American at once, and neither country makes you choose. Polish law doesn’t ban a second citizenship, and a Pole can lose Polish citizenship only by renouncing it. But Article 3 of the Citizenship Act means that, to the Polish state, you are simply Polish: you have the same duties as any Pole and can’t rely on your US citizenship before Polish authorities.

Do I have to give up US citizenship to confirm Polish citizenship by descent?

No. Confirmation recognises citizenship you already hold, and the Act’s chapter on it (Articles 55 to 58) doesn’t make giving up another citizenship a condition. You keep your US passport. US law doesn’t make you choose either, although you must use your US passport to enter and leave the United States.

Can I enter Poland on my US passport if I’m also Polish?

You may get through, but it’s risky. Poland’s Powroty portal says a dual citizen relying on Polish citizenship should show a valid Polish document, and that someone showing only a foreign passport may be treated as a third-country national. The Border Guard told the Ombudsman in 2023 that it must refuse exit to a Polish citizen without a valid Polish document. The Ombudsman disputes that view.

Will I lose Polish citizenship if I become American today?

No. Under Article 34(2) of the Constitution a Polish citizen can’t lose citizenship unless they renounce it, and Article 46 of the Citizenship Act makes that the only way out, with the President’s consent. Naturalising in the US, marrying a foreigner, serving in another country’s forces or living abroad for decades doesn’t end it under the current law.

My great-grandfather became a US citizen in 1930. Did that end Polish citizenship?

It may have. Article 11 of the 1920 Act ended citizenship on acquiring a foreign one. But the same article says a person obliged to do active military service could acquire one only with the military ministry’s permission, and otherwise wouldn’t stop being treated as Polish. So his military status when he naturalised matters. His loss could also extend to his wife and children under 18.

My relative lost Polish citizenship under the old laws. Can it be restored?

If they lost it before 1 January 1999 under the provisions listed in Article 38, the Interior Minister restores it on their application, unless an exclusion applies, such as serving the Axis powers or acting against Poland. It takes effect only when the decision is final, so it doesn’t reach back to a child already born. The application is the former citizen’s own.

Can I renounce Polish citizenship?

Only with the President’s consent. You apply through a voivode or consul with proof of your other citizenship or a promise of one. The President may agree or refuse. Citizenship ends 30 days after the decision, unless the decision sets an earlier date. Polish missions in the US list a fee of 529 USD; in Poland it is 1,669 zł.

Official sources

Checked against these sources on 6 November 2026. The statutes were read in Polish and the translations are ours; the 1920 Act is as published and was amended later. The Sejm’s record listed no change to the 2009 Act after the 2025 consolidated text. The State Department’s public dual nationality page refused automated access that day, so the US position is taken from its Foreign Affairs Manual and the US Code. Consular fees change, so confirm them with your consulate. Only a voivode can confirm your citizenship.
