Citizenship by Descent

Citizenship by descent, also called ancestral citizenship, allows individuals to claim citizenship of a country based on the nationality of a parent, grandparent, or more distant ancestor. Eligibility rules, documentary requirements, and generational limits differ significantly between countries. Italy, Ireland, and Poland are popular options due to relatively broad descent rules. Some nations require the ancestral link to have been maintained through a continuous chain of registration or non-naturalisation elsewhere.
