Jus Soli (Right of the Soil):

Jus soli is a legal principle where a person’s nationality or citizenship is determined by the place of their birth. In countries that follow this principle, individuals born on the country’s territory automatically acquire its citizenship, regardless of their parents’ nationality.

Example: The United States follows jus soli, meaning anyone born within U.S. territory (except for certain exceptions like children of foreign diplomats) automatically becomes a U.S. citizen.

Jus Sanguinis (Right of Blood):

Jus sanguinis is the principle where a person’s nationality or citizenship is determined by the nationality or citizenship of their parents, rather than the place of birth. This system grants citizenship based on descent.

Example: Countries like Germany and Japan primarily follow jus sanguinis, where a child born abroad to German or Japanese parents may still be granted citizenship based on their parents’ nationality.

In some countries, both principles may be used in combination to determine citizenship.
