Poland · Citizenship by descent
Confirmation of Polish Citizenship (Potwierdzenie posiadania obywatelstwa polskiego)
Open
Last verified July 2026
Open and, uniquely in this file, insulated from policy risk: this is a declaratory confirmation that citizenship was never lost, not an application for naturalisation. None of the three pending citizenship bills touch it.
The only route in this file with no policy risk — Poland can tighten naturalisation all it likes and this is untouched, because it confirms a status you already hold rather than granting a new one. But the 1920 Act is a minefield, and the pre-1951 male-line rule silently eliminates a large share of prospective claimants.

What can go wrong
- THE MALE-LINE RULE: under the 1920 Act, children born in wedlock took the father's citizenship only. A Polish grandmother married to a non-Pole transmits nothing for children born before 19 January 1951. Equal maternal transmission arrives only with the 1951 Act. This single rule kills a large share of claims.
- The ancestor must have held Polish citizenship on or after 31 January 1920. Emigration before that date generally kills the claim — there was no Polish state to be a citizen of.
- An ancestor who naturalised elsewhere before 19 January 1951 lost Polish citizenship on taking the oath, and any child born after that date inherits nothing. The chain must be unbroken generation by generation.
- THE MILITARY-SERVICE PARADOX cuts in your favour: under the 1920 Act a man liable for active military service needed Ministry of Military Affairs permission to acquire foreign citizenship. Without it, Poland continued to regard him as Polish despite naturalising, losing it only once he ceased to be liable (broadly around age 50). An ancestor who naturalised while of military age may have retained and kept transmitting Polish citizenship. This rescues claims that look dead on the naturalisation date — but requires evidence of military-age status at naturalisation.
- The 1951 eastern-territories revocation stripped citizenship from inhabitants of former Polish territories east of the Curzon Line annexed by the USSR in 1945, including ethnic Poles. Kresy ancestry is a common dead end.
- Mazowiecki Voivodeship Office backlogs of 1-2 years or more are the main friction.
