Naturalization is the process where an alien becomes a US citizen. In order for an individual to go through the naturalization process, the alien has to meet certain requirements.
An individual can become a US citizen in the following situations:
- A permanent resident who has lived in the US for five years;
- Spouses of US citizens who have lived in the US as a permanent resident for three years;
- Asylees who have lived in the US as permanent residents for four years; and
- Permanent residents with three years of US military service.
