K-1 Fiancé(e) Visa: Requirements, Process and Common Questions

A plain-English guide for U.S. citizens who want to bring a fiancé or fiancée to the United States to marry.

Last updated: November 2026

What is the K-1 fiancé(e) visa?

The K-1 visa lets a U.S. citizen bring a foreign fiancé(e) to the U.S. The couple must marry within 90 days of arrival. After the wedding, the foreign spouse applies for a green card from inside the U.S. A green card holder cannot sponsor a K-1.

Requirements

RequirementWhat it means
U.S. citizen sponsorOnly a U.S. citizen can file. Green card holders cannot use the K-1.
Legally able to marryBoth people must be legally able to marry. Earlier marriages must have ended.
Met in personThe couple generally must have met in person at least once in the two years before filing. Limited exceptions exist for extreme hardship or customs.
Genuine intent to marryBoth must intend to marry within 90 days of the fiancé(e)'s arrival.
Financial supportThe sponsor must show enough income to support the fiancé(e) under the affidavit of support rules.

How the process works

  1. The U.S. citizen files Form I-129F with USCIS, with proof of the relationship and the in-person meeting.
  2. After approval, the case moves to the National Visa Center and then a U.S. consulate.
  3. Medical exam and visa interview at the consulate.
  4. The fiancé(e) travels to the U.S. and the couple marries within 90 days.
  5. After the wedding, the spouse applies to adjust status to a green card.
  6. Work permission can be requested after arrival.

K-1 or spouse visa?

The K-1 is for couples who are not yet married: you marry in the U.S. after arrival. If you are already married, the CR-1/IR-1 spouse visa is the usual route. Which is better depends on your plans, so compare them before filing.

Frequently asked questions

Yes. The K-1 requires marriage within 90 days of the fiancé(e)'s arrival in the U.S.

What if we do not marry within 90 days?

The fiancé(e) must leave the U.S. The K-1 status cannot be changed to another category if the couple does not marry.
