K-1 Fiancé(e) Visa

A K-1 Visa (also known as a Fiancé Visa) is a nonimmigrant visa. Visa issued to the fiancé(e) of a United States citizen. The K-1 Visa allows the visa holder to enter the United States for up to 90 days during which time they may get married and file for Adjustment of Status (to obtain a "green card" and become a Legal Permanent Resident of the US). After filing for Adjustment of Status the spouse may reside in the US beyond the 90-day K-1 Visa validity while the Adjustment of Status application is processed. While the K-1 Visa is legally classified as a non-immigrant visa, it usually leads to important immigration benefits and is therefore often processed by the Immigrant Visa section of United States Embassies and Consulates worldwide. If the non US Citizen fiancé(e) has a child (under 21 and unmarried), a K-2 non-immigrant visa may be available to him or her. 

U.S. citizens who will be getting married to a foreign national in the United States may petition for a fiancé(e) classification (K-1) for their fiancé(e). Foreign national fiancé(e) must be free to marry. You must also have met with your fiancé(e) in person within the last two years prior beginning the K-1 Visa petition process. This requirement can be waived only if meeting the non US Citizen's fiancé(e) in person would violate long-established customs, or if it would create extreme hardship on the US Citizen.
