• Polish citizenship is acquired by birth to any parent who is a Polish citizen at the moment of the child's birth (ius sanguinis a patre et a matre).

Universal Polish eligibility framework: All routes evaluated under (a) Konstytucja Art. 34 ust. 1 (acquisition by birth to Polish-citizen parents) + ust. 2 (voluntary renunciation only); (b) operative era's governing statute (1920/1951/1962/UOP 2009) per Era Map; (c) NSA II OSK 1868/16 burden-on-state evidentiary standard for loss-of-status claims; (d) KPA Art. 77 evidentiary investigation duties on Wojewoda. EU-law overlay: CJEU Rottmann (C-135/08) + Tjebbes (C-221/17) + JY (C-118/20) + Kaur + Zambrano + Chavez-Vilchez + Prefet du Gers proportionality framework where Polish citizenship loss would deprive EU citizenship status. Karta Polaka (2007) intersects multiple routes -- particularly SPC-01 pathway and NAT-01 pkt 4 reduced threshold.

Universal Polish requirements framework: All routes administered by (a) Wojewoda (Potwierdzenie / Uznanie) OR MSWiA (Przywrocenie / preparation for Prezydent Nadanie) OR USC (vital-records registration); (b) KPA framework with Art. 35 par. 3 statutory deadlines + Art. 77 evidentiary investigation; (c) appeal pathway: MSWiA odwolanie within 14 days per KPA Art. 127 -> WSA judicial review -> NSA cassation; (d) sworn translation via tlumacz przysiegly (Ministerstwo Sprawiedliwosci registry); (e) apostille per 1961 Hague Convention (PL party from 2005-08-14) OR Polish embassy legalization; (f) EU public documents under Regulation (EU) 2016/1191 may use Multilingual Standard Form attachment.

Archival sources commonly used: USC (Urzad Stanu Cywilnego) for vital records; IPN (Instytut Pamieci Narodowej) for WWII/PRL records; AAN (Archiwum Akt Nowych) for inter-war administrative records; Archiwa Panstwowe regional branches; Konsulat RP records for paszport konsularny in inter-war diaspora communities; USHMM + Yad Vashem + JewishGen for Polish-Jewish ancestry; AGAD (Archiwum Glowne Akt Dawnych) for pre-1918 partition-era records.

• The declaratory procedure for confirming existing Polish citizenship by descent is Potwierdzenie posiadania obywatelstwa polskiego under UOP Art. 55 — it does not grant citizenship but confirms pre-existing status by uninterrupted descent chain.

Primary authority: Wojewoda (via UOP Art. 55 Potwierdzenie).

Administrative path: administrative; review under KPA framework. Appeal pathway: MSWiA odwolanie within 14 days per KPA Art. 127 -> WSA judicial review (sady administracyjne) -> NSA cassation. Bezczynnosc (inaction) remedy available under KPA Art. 37 (ponaglenie); NSA II OSK 574/25 confirms availability but rarely granted in citizenship matters due to discretionary latitude.

Potwierdzenie posiadania obywatelstwa (UOP Art. 55): declaratory determination -- does not grant citizenship but confirms pre-existing uninterrupted status. Filed with Wojewoda Mazowiecki (overseas applicants -- Warsaw hub) or Wojewoda regional (PL-resident applicants). Documentary submission: applicant identity + complete genealogical chain (vital records all generations) + ancestor pre-loss-event Polish citizenship proof + apostille + sworn translation. Real-world processing: 12-24 months Wojewoda Mazowiecki, 6-12 months regional Wojewoda (PL-EVID-052). KPA Art. 35 par. 3 statutory 1-2 month deadline routinely exceeded due to caseload.
