Obtaining Polish Citizenship from Poland-born Father [3]
@winogrona Hi :) It may be a little late for the reply, but:
1. it is necessary to have your birth certificate to be translated to Polish language;
2. it is also important whether you were born after your parents marriage. If yes, then their marriage certificate will have to be translated to Polish language as well;
3. the application for Polish citizenship confirmation can be found here: file:///C:/Users/malgo/Downloads/wzor_wniosku_o_potwierdzenie_posiadania_lub_utraty_obywatelstwa_polskiego.pdf (pages 2-13)
4. it is not necessary to submit an application personally. In fact, it it easier to submit it by post. Then a certified copy / notary copy of your birth certificate will be necessary
5. also, remember that if you want to apply for the Polish passport, the Polish citizenship confirmation is not enough. It will also be necessary to register your birth certificate in Poland.
I hope it helps!
