If you are of Polish descent, you may be eligible to confirm your Polish citizenship and get Polish passport. However, one of the most important parts of the process is gathering the right set of documents to demonstrate your ancestor’s Polish citizenship and establish that Polish citizenship was passed down through the generations to you.

Polish citizenship is passed by “the right of blood”. If one of the parents holds Polish citizenship (or is a person of Polish descent), it is passed to the child irrespective of whether the child was born in Poland or abroad.
It also applies to people born in countries with the “right of soil” e.g. USA. If you were born in the USA to at least one Polish parent (or a parent of Polish descent – to your Polish grandparents), you can claim Polish citizenship despite the fact you acquired US citizenship at your birth.

If you have a Polish parent, grandparent, or great-grandparent, you may be wondering whether you are eligible for Polish citizenship by descent.
For many people with Polish ancestry, the answer is likely yes—but please keep in mind that Polish citizenship by descent is not simply a matter of proving that you have Polish ancestry. The key question is whether Polish citizenship was legally passed down through your family from one generation to the next.

Polish genealogy archives are organized into three main systems, and knowing which one holds the record you need is the single biggest time-saver in tracing your family tree. Older vital records generally end up in the state archives (Archiwa Państwowe), church baptism, marriage, and burial registers (Księgi Metrykalne) are held by the parish or a diocesan archive, and the newest records — roughly the last century — stay with a local civil registry office (Urząd Stanu Cywilnego, or USC), which restricts access far more tightly.

Confirmation of Polish citizenship (potwierdzenie posiadania obywatelstwa polskiego) is the official administrative procedure that legally recognises you have held Polish citizenship continuously, usually since birth, through a Polish ancestor. It is a declaratory decision, not a grant of new citizenship: the Voivodeship Office (Urząd Wojewódzki) simply confirms a status the law says you already have.

A PESEL number is an 11-digit national identification number assigned to Polish citizens and to people registered as residents in Poland, and it sits at the center of almost every official process you’ll run into after confirming your Polish roots. If you are a Polish citizen living abroad, you will generally need a PESEL number in Poland’s population registry to apply for a Polish passport, Polish national ID , and access Polish government services online.

Polish citizenship for children born abroad works on a simple, well-established principle: if at least one parent holds Polish citizenship at the moment the child is born, the child automatically becomes a Polish citizen too, by the right of blood (ius sanguinis), no matter where in the world the birth takes place.

Polish citizenship confirmation vs restoration – understanding the distinction is critical if you’re seeking to claim or reclaim your connection to Poland. Whether driven by a desire to reconnect with your heritage, live or work in the EU, or ensure future opportunities for your family, obtaining Polish citizenship can open numerous doors. But depending on your family history and individual circumstances, the legal path you must take—confirmation or restoration—is very different.

Obtaining Polish citizenship is a goal for many people with Polish roots. However, the process often depends on locating critical historical documents—birth certificates, marriage records, residency confirmations—that have been misplaced, destroyed or scattered across borders over the course of decades.
