Can I File for My Fiance with a Green Card?
Children of Fiancé(e)s If your fiancé(e) has a child who is under 21 and unmarried, the child may be eligible to come to the United States on a K-2 nonimmigrant visa. You must include the names of your fiancé(e)’s children on the Form I-129F if you wish to bring them to the United States.
