Polish citizenship by descent: who qualifies, the law, and what it takes

Q: Can you claim Polish citizenship through a parent?

Possible. If your ancestor held Polish citizenship after 1920 and nobody in the line lost it before the next birth, you may already be a Polish citizen and can ask to have it confirmed. If someone in the line became a citizen of another country before the next person in the line was born: unlikely. If someone in the line naturalized elsewhere while their child was still a minor: unlikely. If your ancestor left Poland before 1920: unlikely.

Q: Can you claim Polish citizenship through a grandparent?

Possible. If your ancestor held Polish citizenship after 1920 and nobody in the line lost it before the next birth, you may already be a Polish citizen and can ask to have it confirmed. If someone in the line became a citizen of another country before the next person in the line was born: unlikely. If someone in the line naturalized elsewhere while their child was still a minor: unlikely. If your ancestor left Poland before 1920: unlikely.

Q: Can you claim Polish citizenship through a great-grandparent?

Possible. If your ancestor held Polish citizenship after 1920 and nobody in the line lost it before the next birth, you may already be a Polish citizen and can ask to have it confirmed. If someone in the line became a citizen of another country before the next person in the line was born: unlikely. If someone in the line naturalized elsewhere while their child was still a minor: unlikely. If your ancestor left Poland before 1920: unlikely.

POSSIBLE

Can you claim Polish citizenship through a parent?

Confirmation of Polish citizenship

If your ancestor held Polish citizenship after 1920 and nobody in the line lost it before the next birth, you may already be a Polish citizen and can ask to have it confirmed.

A person who holds Polish citizenship may apply to the voivode for confirmation; the decision looks back through each generation for acquisition and loss. Act on Polish Citizenship of 2 April 2009 (confirmation of possession of citizenship), art. 55
Under the 1951 Act, people who lived abroad and held foreign citizenship were in many cases deprived of Polish citizenship, and their minor children under 13 with them; the details of your line decide it. Act on Polish Citizenship of 8 January 1951

What changes the answer

POSSIBLE
If the parent is your mother
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962
UNLIKELY
If someone in the line became a citizen of another country before the next person in the line was born
Under the pre-1951 law, taking another citizenship generally meant losing Polish citizenship, so a child born after that did not receive it. One exception: men who had not completed Polish military service.
POSSIBLE
If you don’t know whether anyone in the line naturalized elsewhere before the next birth
Whether your ancestor naturalized elsewhere, and when, relative to the next birth in the line.
UNLIKELY
If someone in the line naturalized elsewhere while their child was still a minor
Under the 1920 Act, when a father lost Polish citizenship by naturalizing abroad, his children under 18 lost it with him, so the line usually ended there. The exception is a father whose military-service obligation kept him Polish.
UNLIKELY
If your ancestor left Poland before 1920
An ancestor who left before 1920 was never a citizen of the Polish state, which came into being in 1918 and defined its citizens in 1920.

02Dates that matter

The dates that matter

1962
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962

03Mothers’ lines

How mothers’ lines were treated

In Poland’s rule, the answer changes when the line runs through a woman:

POSSIBLE
If the parent is your mother
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962
POSSIBLE
If the grandparent is your grandmother
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962
POSSIBLE
If the great-grandparent is your great-grandmother
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962

In the law’s words

Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962
The Supreme Administrative Court has applied this to children of fathers naturalized abroad during their minority (II OSK 1988/09, II OSK 1617/09, II OSK 50/10). Supreme Administrative Court (NSA): II OSK 1988/09 (13 Oct 2010), II OSK 1617/09 (29 Sep 2010), II OSK 50/10 (30 Nov 2010), Central Database of Administrative Court Rulings

04Keeping your citizenship

Dual citizenship with your home country

You keep your citizenship.

On every open route, the rule lets a citizen of the United States, Canada, the United Kingdom, Australia, New Zealand, Brazil, Argentina or South Africa keep that citizenship.

Polish law does not require a Polish citizen to renounce another citizenship. Act on Polish Citizenship of 2 April 2009 (confirmation of possession of citizenship), art. 3
Polish citizenship as a legal status dates from the 1920 Act; those already settled abroad and holding another citizenship by then were generally not Polish citizens. Act on Citizenship of the Polish State of 20 January 1920

05The routes

The law

A person who holds Polish citizenship may apply to the voivode for confirmation; the decision looks back through each generation for acquisition and loss. Act on Polish Citizenship of 2 April 2009 (confirmation of possession of citizenship), art. 55
Under the 1951 Act, people who lived abroad and held foreign citizenship were in many cases deprived of Polish citizenship, and their minor children under 13 with them; the details of your line decide it. Act on Polish Citizenship of 8 January 1951
Until the 1962 Act, a legitimate child generally followed the father's citizenship; a line through a Polish mother and foreign father before 1962 may not carry it. Act on Citizenship of the Polish State of 20 January 1920, art. 5; Act of 15 February 1962
Acquisition of a foreign citizenship caused loss of Polish citizenship, except for persons still subject to military service who had not been released from it. Act on Citizenship of the Polish State of 20 January 1920, art. 11
The loss of Polish citizenship extended to the wife and to children under 18, unless the Minister's decision provided otherwise. Act on Citizenship of the Polish State of 20 January 1920, art. 13
The Supreme Administrative Court has applied this to children of fathers naturalized abroad during their minority (II OSK 1988/09, II OSK 1617/09, II OSK 50/10). Supreme Administrative Court (NSA): II OSK 1988/09 (13 Oct 2010), II OSK 1617/09 (29 Sep 2010), II OSK 50/10 (30 Nov 2010), Central Database of Administrative Court Rulings
Polish citizenship as a legal status dates from the 1920 Act; those already settled abroad and holding another citizenship by then were generally not Polish citizens. Act on Citizenship of the Polish State of 20 January 1920

What would settle an unsure case

The naturalization date, the next birth date, and for a man, whether he was of military age and released from Polish service.
Whether your ancestor naturalized elsewhere, and when, relative to the next birth in the line.
The child's exact age at the father's naturalization (under 18 means the loss passed), whether it happened before 19 January 1951, and whether the father was still under a Polish military obligation, which prevented the loss.
Whether your ancestor was registered as a resident of Polish territory on or after 31 January 1920, or held a Polish passport.

06The documents

The documents, as the rule lists them

Confirmation of Polish citizenship

Through a parent or grandparent or great-grandparent

Your ancestor's Polish birth or residence record, passport, or military record
Their marriage record
Any naturalization record abroad, with its date
Birth and marriage records for each generation to you

Most countries also want proof that no one in the line became a citizen elsewhere before the next birth: the naturalization record with its date, or a letter that none exists.

07What it takes

What it takes: time, cost, the hard part, who decides

Confirmation of Polish citizenship

Time: 12–24 months for the confirmation decision, then 2–3 months for a passport.
Cost: About $600–1,500: through a U.S. consulate, the $118 consular fee (277 PLN if filed directly with a voivode in Poland), plus $47 per copy the consul certifies, sworn translations of every U.S. document, apostilles and, usually, archive searches in Poland.
The hard part: Proving your ancestor held Polish citizenship after 1920 and that no one in the line lost it before the next birth. That means Polish civil records plus each generation’s U.S. naturalization date.
Who decides: The voivode (provincial governor) for your own current or last address in Poland, or the Masovian Voivode in Warsaw if you never lived there, through the Polish consulate for your U.S. address.
The first record: Your ancestor’s Polish birth or marriage record, or a pre-war passport or military record, from The Polish State Archives (szukajwarchiwach.gov.pl) and the local civil registry (USC). Search the archives portal by name and town; scanned registers cover much of Poland. For records under 100 years old, write to the USC of the town. szukajwarchiwach.gov.pl

How it’s filed

Where: The Polish consulate for your U.S. state, which forwards to the voivode: Embassy Washington (DE, DC, GA, KY, MD, NC, PA, SC, TN, VA, WV, USVI and other territories, PR); Chicago (IL, IN, IA, MI, MN, MO, NE, ND, OH, SD, WI); Houston (AL, AR, FL, KS, LA, MS, NM, OK, TX); Los Angeles (AK, AZ, CA, CO, HI, ID, MT, NV, OR, UT, WA, WY); New York (CT, ME, MA, NH, NJ, NY, RI, VT). Alternatively posted directly to the voivode. office list
How: By post; no appearance needed
Form: Wniosek o potwierdzenie posiadania lub utraty obywatelstwa polskiego (statutory form, Dz.U. 2012 poz. 925)
Appointments: e-Konsulat (System Zdalnej Rejestracji), category 'Sprawy obywatelskie'. Booking passes an image-verification (captcha) step; the consulate page says documents may be filed in person or by post, so a visit is optional unless you want the consul to certify copies.
Fee: About $118
Decision: 6–24 months

What goes in the file (9)

Completed application in Polish, signed
Current passport or ID, original with all pages bearing official annotations (for inspection)
Your full (long-form) birth certificate with parents' names, apostilled, with Polish sworn translation
Your marriage certificate, divorce decree or spouse's death certificate, apostilled and translated
Name-change documents, where they apply
Birth and marriage records for each generation back to the Polish ancestor, apostilled and translated
The ancestor's Polish records: birth or baptismal record, pre-war Polish passport, ID, military book, residence register entry
Each generation's U.S. naturalisation certificate or a USCIS/NARA record showing its date, or proof of none
Copies certified as true by the consul (bring the originals; consular tariff item 6.03 is $47)

What goes wrong (8)

Fee: through a U.S. consulate you pay the consular tariff, $118, instead of the domestic stamp duty of 277 zł (raised from 58 zł on 1 August 2025). Payment by card, cash, money order or cashier's check; Los Angeles takes no cards; by post only money order or cashier's check.
Competent voivode: the one for your current or last place of residence in Poland; if you never lived in Poland, the Wojewoda Mazowiecki (Warsaw). Not the ancestor's last address.
Since 1 August 2025 the voivode has 6 months to decide, but time waiting on archives, other offices or missing documents does not count; real cases run 12–24 months.
One application per person; minor children need their own applications.
Appeal within 14 days of delivery, to the Minister of the Interior through the voivode.
U.S. documents need an apostille from the issuing state; all foreign-language documents need a Polish sworn translation.
Naturalisation dates decide the case: under the 1920 Act, naturalising abroad before the next birth ended the line unless the man was still subject to military service; check each generation against the 1951 and 1962 Acts.
From CA/GB/AU/NZ/BR/AR/ZA: file through the Polish consulate for your residence; that country's consular tariff replaces the $118 and the 277 zł.

The Urząd Stanu Cywilnego (USC, civil registry office): birth records for 100 years, marriage and death records for 80 years
Any USC in Poland can issue a copy of a record already in the electronic civil register; for a record still only on paper, the USC of the town where the event was registered (or the one that now holds that town's books) issues it. Records from the pre-war eastern territories (now Ukraine, Belarus, Lithuania) under 100 years old are held in Warsaw (the 'Zabużański' archive of the Warsaw USC).

- Fees: 33 zł for a full copy (odpis zupełny), 22 zł for a short or multilingual copy; a proxy in Poland adds 17 zł for the power of attorney. Ask for the odpis zupełny: it shows parents and annotations the voivode needs.
- Descendants (zstępni) are entitled to copies without further proof of interest; enclose the birth records linking you.
- Online filing via gov.pl needs a Polish Profil Zaufany or e-ID and, from 2026, an e-Doręczenia address, which U.S. filers do not have; a signed letter by post with a bank transfer is the practical route.
- Statutory time: 7 days if the act is already digitised, about 10 working days if the office must digitise it; add international post.

Search szukajwarchiwach.gov.pl by town or parish to find which state archive branch holds the register, and often the scan itself. Pre-1918 records from the Russian partition are in Russian (after 1868) or Polish; Prussian partition records are German civil registers from 1874; Austrian partition records are Latin/Polish parish books. Records of the former eastern territories older than 100 years are largely at AGAD in Warsaw.

Translations

Into: Polish
Who may translate: A sworn translator in the country
About: $15–$71 a page

All foreign-language documents need an official Polish translation by a sworn translator (tłumacz przysięgły) on the Polish Ministry of Justice list, an EU/EEA sworn translator, a translator whose translation the consul certifies, or the consul. The U.S. consular tariff is $71 per page for civil-status documents (repetitive content) and $141 per page otherwise; Polish sworn translators usually cost far less (low end of the range is an estimate). The application form itself must be filled in Polish.
