The K-1 visa allows a foreign fiancé(e) of a U.S. citizen to enter the United States to get married within 90 days of arrival. If the foreign fiancé(e) has unmarried children under 21, they may qualify for a K-2 visa and accompany their parent to the U.S.
The K-1/K-2 visa process allows U.S. citizens to bring their foreign fiancé(e) and future stepchildren to the U.S. to begin a life together. With the right documentation and timing, families can stay united from the very start of their immigration journey.
