To become a U.S. citizen, Jose must meet the following requirements:
- He must take a citizenship test.
- He must wait at least five years.
These two options are correct as part of the naturalization process. The citizenship test assesses knowledge of U.S. history, government, and an understanding of the English language. Additionally, most applicants must be permanent residents (green card holders) for at least five years before applying for citizenship, though there are exceptions for certain categories such as spouses of U.S. citizens. The other options provided (marrying a citizen and promising to serve in the military) are not universal requirements for naturalization.
