A U.S. citizen is an individual who is recognized as a legal member of the United States. This status can be acquired by birth within the country, through U.S. citizen parents, or by naturalization, which is a legal process for immigrants. U.S. citizens have specific rights and responsibilities, including the right to vote in elections and the obligation to pay taxes. Citizenship also grants individuals access to various benefits, such as the ability to apply for a U.S. passport and receive protection from deportation. U.S. citizens are expected to uphold the laws of the United States and participate in civic duties, contributing to the nation's democratic process.
