To become a citizen of the United States, there are several paths one can take. Here are some ways that apply:
1. **Birthright Citizenship**: A person is born in the United States. This is guaranteed by the 14th Amendment of the U.S. Constitution.
2. **Naturalization**: An eligible foreign national can become a citizen through the naturalization process, which typically involves meeting residency requirements, demonstrating good moral character, knowledge of English, and understanding of U.S. history and government.
3. **Citizenship through Parents**: A person may acquire U.S. citizenship at birth if they are born abroad to U.S. citizen parents who meet certain residency requirements.
4. **Military Service**: Some individuals may also gain citizenship through serving in the U.S. military.
These methods outline the primary ways through which a person can become a citizen of the United States.
