The K-1 visa was only granted to allow your fiancé(e) to be married to you. He or she will now be required to return home. Your fiancé(e) will begin a period of “unlawful stay” when the K-1 admission period ends. If your fiancé(e) stays in the U.S. for more than six months but less than a year after the K-1 admission period ends, he or she will not be able to return to the U.S. for three years. If the period is more than a year, he or she will not be able to return for ten years.
