Question: How soon after receiving your green card are you able to apply for citizenship? Â I am a lawful permanent resident and have been married to a U.S. citizen about a year and a half ago.
Answer:  In order to apply for citizenship, you have to be a lawful permanent resident for 5 years. You can apply 3 months early, so add 4 years and 9 months to the date that you received your green card.
