Children of Polish citizens would inherit their parents’ Polish citizenship, even if those children were born abroad or had just one parent with Polish citizenship. Inheriting Polish citizenship was possible even if parents gained their Polish citizenship after migrating from Poland. It was however required that the parents were Polish citizens when the child was born.

From 1920 to 1951 children inherited their Polish citizenship from their fathers, if the child was born to a married couple, or from their mother, if the child was born outside of marriage.

FAQ for Polish citizenship by descent


Citizenship by descent – Jewish Community

One of the most important dates in terms of confirming Polish citizenship is January 31, 1920. It is the date when the provisions of the Polish Citizenship Act came into force – the first Polish act granting Polish citizenship. The citizenship was granted by operation of law to practically all residents of the territories that fell to the newly established Polish State as a result of World War I.

The Polish citizenship was granted to all those settled in the territory of the Polish State, regardless of gender, age, religion and nationality. Among the residents of the territory of the young state was also a Jewish community, numbering over 3 million Jews at that time, which was one of the largest diasporas in the world.

Growing anti-Semitism throughout Europe often forced Jewish families to emigrate from Europe to other countries, e.g. the USA, Canada, Latin America etc.. Leaving their homes, sometimes without any documents, Jewish immigrants did not even realize that they had Polish citizenship, because they acquired it automatically, under the provisions of the Act, and not as a result of the citizenship acquisition procedure.

In a situation where these Jews did not obtain foreign citizenship, did not start military service or did not accept a public office abroad by January 19, 1951 (i.e. when the next Act on Polish citizenship came into force) – they retained their Polish citizenship and also transferred this citizenship to their descendants in accordance with the so-called law of blood (Ius sanguinis).

In relation to descendants of Polish Jews, there are no exceptions to the procedure for confirming Polish citizenship – the rules are the same for all nationalities. First of all, the applicant has to present the voivode with documents confirming that:

  • the applicant’s ancestors held Polish citizenship,
  • there are no circumstances indicating that they have lost their citizenship, and
  • that Polish citizenship has been transferred to their descendants in the direct line.

In the case of persons currently residing outside Poland, the application can be submitted through the Polish consul at the place of residence or using the services of a proxy, preferably an attorney or legal adviser – directly to the voivode competent for the last place of residence of the applicant’s ancestors, and if this place is unknown – to the Mazovian Voivode.

A decision on the application is usually issued within about a year.

My great-grandfather was a Jew and lived in Warsaw on January 31, 1920 and shortly afterwards emigrated to the USA. He was not of Polish nationality and was not a Catholic. Did he have Polish citizenship?

Yes, he obtained Polish citizenship based on Polish Citizenship Act of January 20, 1920. Settling on the territory of Poland at that time meant acquiring citizenship regardless of nationality, age, gender or religion. The acquisition of citizenship was contingent on residence in the then territory of Poland, regardless of nationality, age, gender or religion.

My great-grandparents were Jews and emigrated to Canada in 1918. Before that, they had been permanently resident in Łódź. Did they acquire Polish citizenship?

Although great-grandparents did not permanently reside in Poland on January 31, 1920, they could acquire citizenship based on the provisions of international agreements, such as the Little Treaty of Versailles, which granted Polish citizenship to, among others, people born in the territory that was assigned to the newly established Polish State after World War I, of parents who were permanently resident there, even if these people themselves did not have permanent residence there at the time the Treaty came into force.

My Jewish great-grandfather was born in Poznań in 1901 and lived in Poland the entire time. Before the war, in 1938, he emigrated to Great Britain. After the outbreak of the war, he joined the Polish Corps formed by the British government. Did my great-grandfather lose Polish citizenship due to his service in a foreign army?

According to the generally accepted position of Polish judiciary, participation in a foreign army on the side of the Allies during World War II did not result in the loss of Polish citizenship.

My grandparents were Polish citizens, who became naturalized American citizens. Did they loose their Polish citizenship?

From 1920 to 1951 acquiring a foreign citizenship meant loosing Polish citizenship. The exception to that were men liable for active military service – they needed a special permit from Ministry of Military Affairs to get a foreign citizenship. If a man did not get such a permit, Polish state would still consider him to be a Polish citizen. That man would loose his Polish citizenship only after he was no longer liable for active military service (usually – until he turned 50). Situation in which a man was still a Polish citizen despite acquiring a foreign citizenship is called „a military paradox”.

My grandfather was born in 1919 in Poland, he became a naturalized American citizen in 1938, was he a Polish citizen?

The grandfather became a Polish citizen in 1920 when the Act of 1920 came into force. He could not loose his Polish citizenship when he was naturalized due to the military paradox (see question No. 13). In 1951 a new act on Polish citizenship came into force, which did not link acquisition of a foreign citizenship with loosing Polish citizenship. Given that until that new act came into force the grandfather did not turn 50, he never lost his Polish citizenship.

My grandfather was born in Lublin, Poland in 1908, he migrated with his parents in 1917 to the US. Did my grandfather become a Polish citizen?

Yes, he acquired his Polish citizenship on the basis of the Act of 1920. If he did not loose his Polish citizenship, he could pass it down to his descendants.

My great-grandparents were born before 1920 in the US, their parents migrated from Poland. Did my great-grandparents become Polish citizens?

Unfortunately, people born abroad (outside of Poland) before 1920, even if they were born to Polish parents, did not automatically become Polish citizens. That means, that there could be instanced in which Polish immigrants, who were born in Poland before 1920, did become Polish citizens, however their children, born abroad and before 1920, never acquired their Polish citizenship.

Was it possible for a person born abroad (outside of Poland) and before 1920 to become a Polish citizen?

It was possible – a citizen of another country with Polish ancestry, if he or she returned to Poland and motioned to be recognised as a Polish citizen, they and their descendants would become Polish citizens as long as they could provide evidence of their Polish ancestry.

I was born in 1962 in Canada, only one of my parents was a Polish citizen. Is it possible to confirm my citizenship?

For people born after 1951 it is enough to have one parent with Polish citizenship to become a Polish citizen by birth. That parent can be either a mother or a father, it does not matter. That rule of inheriting Polish citizenship through one parent has not changed to this day.

My great-grandfather was born in Poland in 1880. He became a naturalized American citizen in 1915. Was he a Polish citizen?

Unfortunately no, only people who did not have a foreign citizenship when the Act of 1920 came into force acquired Polish citizenship. In this context „foreign citizneship” means citizenship of countries other then Poland, Germany, Austria-Hungary and Russia.

My grandparents were Polish citizens who were forced to accept Soviet citizenship during the war. Is it possible for me to confirm my Polish citizenship?

Generally speaking, Polish courts usually state that mandatory granting of the Soviet citizenship could not result in loosing Polish citizenship – one would loose Polish citizenship only if one willingly accepted a foreign citizenship. It might be possible to confirm Polish citizenship of a descendants of people forced to accept Polish citizenship, with some exceptions (see question 21).

My grandparents were Polish citizens, they lived in the part of Poland that was annexed by the USSR during WWII, they were granted Soviet citizenship during the war and continued to live in the USSR after the war. Is it possible to confirm my Polish citizenship?

As stated in question 20, those forcefully granted Soviet citizenship did not loose their Polish citizenship. However, Poland and USSR concluded a Convention in 1957, according to which those who were both citizens of Poland and USSR had to choose to have only one of the two (either Polish or Soviet citizenship).

Those who did not file such a declaration with their choice, would be consider citizens of the country they lived in and would loose the citizenship of the other country. In this case, if the grandparents lived in the USSR in 1957 and they did not file a declaration in which they chose to be Polish citizens, they lost their Polish citizenship. Confirming Polish citizenship of their descendants would be impossible.
