"Born or naturalized" refers to two methods by which individuals can obtain U.S. citizenship. Those who are born on U.S. soil automatically acquire citizenship (birthright citizenship). Alternatively, individuals can become citizens through the process of naturalization, which involves meeting certain criteria and going through an application process.
