If you remain married, you can apply for citizenship 3 years from the date your green card was issued, not the date you entered the U.S., unless your green card was issued prior to or at the same time you entered the U.S. If you obtain a divorce, you must wait 5 years from the date your green card was issued to apply for citizenship.
