What Is a K-1 Fiancé(e) Visa?
A K-1 visa allows the foreign fiancé(e) of a U.S. citizen to travel to the United States for the purpose of marrying the U.S. citizen petitioner.
After entering the United States in K-1 status, the couple must marry within 90 days.
Following the marriage, the foreign spouse generally must complete a separate process with USCIS to apply for lawful permanent residence through adjustment of status.
The K-1 visa therefore is not itself a green card.
