Citizenship is obtained through a process called 'naturalization'. Naturalization is a voluntary process that requires applicants to meet certain eligibility requirements, including but not limited to filing an application, being 18 years of age or older, being a permanent resident of the United States, and demonstrating good moral character.

Naturalization gives you many rights and responsibilities on citizens, such as the right to vote, the right to hold public office, and the responsibility to serve on a jury when called upon. Naturalization also allows citizens to apply for a U.S. passport and travel freely outside the United States.
