After the USCIS approves a K1 fiance visa, the approved petition is sent to the appropriate U.S. Embassy abroad where the K1 beneficiary is interviewed by a consular officer. Most K1 petitions that are not successful are denied at this stage. The most common reason for the denial is on the grounds that the relationship is not "bona fide." In short, this means that the consular official believes that the relationship may exist only for the purpose of obtaining U.S. immigration benefits or is otherwise not a legitimate relationship.
