What do I need to become a US citizen?

Generally speaking, if you are not a US citizen by birth, you would have to be a permanent resident for five years, spend most of the time (over half) during that period of residency in the country, and not be excludable or deportable for any of the reasons as outlined by the form N- 400 questions in Part 10. If you are married to a US citizen and living together for three years, you can also apply for naturalization in three years after obtaining conditional or permanent residentce provided your US citizen spouse has held US citizenship for the three years.
