The Pole’s card confirms the foreigner’s belonging to the Polish nation, but it does not legalize his stay on the territory of the Republic of Poland. To come here, you must have a document legalizing your stay.
On the other hand, having a Pole’s Card may facilitate the legalization of your stay. Thanks to it you can get a visa for free, which entitles you to repeatedly cross the Polish border.
Having a Pole’s Card enables you also many rights, such as the possibility of submitting an application for Polish citizenship for free, taking up a job in Poland without having documents that legalize it, free museum visits.
There are more benefits of having a Pole’s Card, so if you have one, be sure to acknowledge them!
