Which law determines citizenship based on where a person is born?

The law that determines citizenship based on where a person is born is known as "jus soli," which translates to "right of the soil." This legal principle grants citizenship to individuals born on the territory of a state, regardless of the nationality of their parents. In countries that follow jus soli, being born within national borders typically confers full citizenship rights, allowing individuals to participate in society as citizens.

In contrast, jus sanguinis, or "right of blood," bases citizenship on the nationality or citizenship of one's parents rather than the location of birth. Naturalization is the legal process through which a non-citizen may acquire citizenship, typically after meeting certain requirements. The Patriot Act primarily pertains to counter-terrorism measures and does not address citizenship laws directly. These differences highlight why jus soli is the correct answer in identifying the principle of citizenship by birthplace.
