To become a citizen of the United States, the following options apply:
- A person is born in the United States.
- A person of foreign birth successfully completes the naturalization process.
- A person marries someone who is already a U.S. citizen (this can expedite the naturalization process, though the person still needs to complete the necessary steps).
The option regarding living in the U.S. for five years is relevant as it is one of the general requirements for naturalization, but it is not a standalone method for becoming a citizen without completing the naturalization process.
Therefore, the responses that apply are:
- A person is born in the United States.
- A person of foreign birth successfully completes the naturalization process.
- A person marries someone who is already a U.S. citizen.
