Benefits of the K-4 Visa
The K-4 Visa allows unmarried children under the age of 21 of a K-1 Visa beneficiary to enter the U.S. along with their parent to join the U.S. citizen. It facilitates early entry for the children, avoiding family separation and allowing them to remain lawfully in the country while the parent applies for adjustment of status.
