What refers to citizenship by descent or right of blood?

Citizenship by descent, also known as jus sanguinis or the right of blood, is a legal principle that grants nationality based on one’s family lineage rather than place of birth.

This differs from jus soli, or birthright citizenship, which is granted to anyone born within a country’s borders.

Under ancestry citizenship, individuals can apply for a passport if they can prove direct ancestry to citizens of another country, usually through parents, grandparents, or in rare cases, great-grandparents.

Documentation requirements vary but typically include birth, marriage, and naturalization certificates tracing the family line.

This pathway is especially attractive to those with ancestral ties to Europe, Latin America, or parts of the Middle East, where many countries maintain inclusive citizenship laws for descendants abroad.
