We will not count for the first analysis of your case then starting this process won't cost you anything. The action you need to take is to prepare every polish document which you have such as a birth certificate, marriage certificate, or death certificate. Hence, some documents are crucial for getting a positive decision.
The documents we write about here are so important because they seem only for Polish citizens, hence they are proof of the Polish origin of your parents or your ancestors.1. Paszport (Passport) confirms both identity and citizenship. On the first page of the cover you will find the words: "Paszport - Rzeczpospolita Polska" or "Paszport - Polska Rzeczpospolita Ludowa".
4. Karta Meldunkowa (Registration Card) - Each resident in Poland was obliged to register at the office of his place of residence. Similarly, owners of tenement houses were obliged to keep a register of tenants. In the past, it was not easy to register your stay, only Polish citizens could do it. Hence, the registration card is also an important document confirming Polish citizenship.
Książeczka wojskowa/Zeszyt ewidencyjny (Military
book/Registration Book) - Each soldier receives a military book that confirms his service. It seems that this document has
little to do with the citizenship of a given country. In Poland, service in the
army is only allowed for Poles.
In connection with this, the military book confirms Polish citizenship. Hence its usefulness.
