To become a U.S. citizen, the following options apply:
- A person is born in the United States. (This grants automatic citizenship.)
- A person of foreign birth is granted citizenship after living in the U.S. for five years. (This typically refers to the residency requirement before applying for naturalization.)
- A person of foreign birth successfully completes the naturalization process. (This is the formal process through which a foreign national becomes a U.S. citizen.)
- A person marries someone who is already a U.S. citizen. (This can expedite the naturalization process for the spouse.)
So, all options provided can lead to U.S. citizenship.
