A person who has a U.S. citizen fiancé may apply for a K-1 visa to join their partner in the U.S. The K-1 visa permits the foreign national fiancé to travel to the U.S. and marry their U.S. citizen sponsor within 90 days of arrival and to subsequently apply for a green card visa with the Department of Homeland Security (DHS) and United State Citizenship and Immigration services (USCIS).
Unmarried children under 21 years of the foreign national spouse are eligible to apply and travel with the fiancé on a K-2 visa. There are no quotas or limits on the number of people who can obtain fiancé visas and subsequent green cards through marriage to a U.S. citizen. A fiancé visa can take anywhere from 6 months to a year or more to obtain, depending on how backed up the various offices dealing with the applicant’s file are.
