What is the difference between the K-1 visa for fiancé (e) s and the K-3 visa for spouses?
The K-1 visa is issued to the fiancé(e) of a U.S. citizen who will marry in the United States and apply to take up permanent residence after marriage. The K-3 and K-4 visa is issued to the spouse(K3) of a U.S. citizen who is the beneficiary of an immediate relative petition and his/her child(ren)(K4) under the age of 21. The K-3 and K-4 visa allows the holder to travel to the United States to reside while his or her immigrant visa petition is being processed by the United States Citizenship and Immigration Services (USCIS) and to apply for an immigrant visa once the petition has been approved.
