Anyone know about this? Citizenship by descent Citizenship can generally be claimed only by descendants of Polish citizens who left Poland after the country became an independent state in 1918. Also, there can be no break in Polish citizenship between the emigrant ancestor and the descendant. If the applicant's ancestor lost Polish citizenship, such as by becoming a citizen of another country before 1951, the descendant did not inherit Polish citizenship through that ancestor. Application for "Confirmation of Possession or Loss of Polish Citizenship" can be made through Polish embassies or consulates abroad." Does this mean that if my son's ancestor left Poland in 1920, and was never naturalized in the US, he can claim Polish citizenship? We are looking for international training (academy) and playing opportunities for my son, based on his lineage, and so far Poland seems to be the only option. Since they are a member of the EU, this could open doors for my son. I'm wondering if anyone has thoughts on this approach.
