Normally you must be a lawful permanent resident for 5 years before you can apply for naturalization. However, if you are married to a United States Citizen and leaving in marital union with your citizen spouse (i.e. actually living together as husband and wife and not just married on paper) you can apply after being a resident for 3 years. In either situation the application can be filed 90 days in advance of your eligibility date.
