I am a legal permanent resident. How do I become a U.S. citizen?
You may apply for US citizenship if you have continuously lived in the United States for at least 7 years. If you are married, you may apply after 3 years of being a green card holder, other wise you must generally wait 5 years from the date you become a green card holder. You must not have been convicted of any crimes in which your character may be put into question and you must be proficient in speaking and writing English. Finally, you must be able to answer questions about American history and civics. See a sample of the types of questions you might see.
