The K3 visa, or spouse visa, is a non-immigrant visa for a spouse of a US citizen to enter the United States while their permanent stay case is pending. This visa is intended to minimize the separation between a married couple of a foreign citizen and US citizen while awaiting the approval of their immigrant visa petition. The spouse of a US citizen applying for a non-immigrant K3 visa must have an immigrant visa petition filed on their behalf by a US citizen.
