Spouses of U.S. citizens who are citizens of another country and reside outside of the United States, can use the K-3 Visa to enter the United States while waiting to obtain the green card or in other words, become a lawful permanent resident. The K3 Visa is designed for couples who were legally married outside of the United States.
The K3 Visa is a temporary visa that allows a foreign citizen who is married to a U.S. citizen and lives abroad to apply for the K-3 Spouse Visa in order to come to the United States and become a permanent resident of the United States. This visa category seeks to unite the families of U.S. citizens and shorten the physical separation between husband and wife while the foreign-born spouse awaits approval of immigration benefits from the U.S. government. Moreover, eligible children of K3 Visa applicants are issued a K-4 Visa which allows them to come and live in the United States while waiting for a decision on the green card.
