Form I-129F: Petition for Alien Fiancé(e)

Form I-129F is the petition U.S. citizens file to bring a foreign fiancé to the United States on a K-1 nonimmigrant visa. Only U.S. citizens — not LPRs — can file. The petition must show the couple has met in person within the two years before filing, both are legally free to marry, and both intend to marry within 90 days of the fiancé's arrival.

The I-129F is followed by consular processing at the fiancé's home country embassy. On approval and entry, the couple must marry within 90 days; the fiancé then files Form I-485 to adjust to conditional permanent resident status.

The USCIS filing fee for Form I-129F is $675 as of the April 2024 fee schedule. Additional State Department fees apply at the consular stage — the K-1 visa fee is currently $265.
