In order for the K-1 visas to be approved, the petition must submit satisfactory evidence, to the discretion of the Secretary of Homeland Security, that the parties have previously met in person within 2 years before the date of filing the petition and have a bona fide intention to marry. The parties must also submit evidence that they are legally able and actually willing to conclude a valid marriage in the United States within a period of 90 days after the alien's arrival.
The Secretary of Homeland Security may waive the requirement that the parties have previously met in person, in his discretion. If you are applying for a waiver to show that you and your Fiancé(e) were unable to meet previously, you must provide sufficient evidence to show that (1) meeting each other would violate the long-established customs of your or your fiancé(e)’s foreign culture or social practice, or (2) meeting each other would result in extreme hardship to you, the petitioner.
