If any of your ancestors (parents, grandparents, great-grandparents) were Polish, you may be eligible to obtain a Polish/EU passport.
A child born in any country to a Polish parent, in most cases, will have inherited Polish citizenship.
For this reason, it is possible for Polish citizenship to be “passed down” through many generations. Therefore, you could be eligible for Polish citizenship even if neither of your parents holds a Polish passport.
