In depth
Potwierdzenie posiadania obywatelstwa polskiego (confirmation of Polish citizenship) is the legal process by which the Polish government confirms that a person is a Polish citizen by descent. The confirmation is retroactive — the applicant is deemed to have been a Polish citizen since birth.
The process is governed by the Polish Citizenship Act of 2009 (as amended). Applications are filed with the Wojewoda (provincial governor) of the applicant's last place of residence in Poland, or with the Polish consulate abroad.
Polish citizenship passes by blood with no generational limit, provided the line was never broken. The historical overlay (partitions 1795-1918, WWII 1939-45, border changes 1945) creates documentation gaps that Our network of genealogists specialize in bridging.
Example
A Polish-American whose great-grandfather emigrated from Warsaw in 1912 can apply for potwierdzenie to confirm Polish citizenship.
