Important information

A visa does not guarantee entry; a US Customs and Border Protection officer decides admission at the port of entry. The K-1 also requires marriage to the petitioner within 90 days of entry.

Who it is for

The K-1 visa is for a foreign national who is engaged to a US citizen and plans to marry that citizen in the United States. It is designed for couples who intend to build their life together in the US rather than for a temporary visit.

It is not available where the petitioner is a lawful permanent resident (green card holder) rather than a US citizen. Couples who are already married generally use a spouse immigrant visa or other spousal routes instead of the K-1.

Eligibility requirements

  • The petitioner must be a US citizen.
  • Both partners must be legally free to marry, meaning any previous marriages have been legally ended.
  • The couple must intend to marry within 90 days of the fiancé(e)'s admission to the United States.
  • The couple must generally have met in person within the two years before the petition is filed, unless a waiver applies.
  • The applicant must be otherwise admissible to the United States under US immigration law.

How to apply

The process runs in stages, starting in the US and finishing at a consulate abroad.

  • The US citizen files Form I-129F, Petition for Alien Fiancé(e), with USCIS.
  • USCIS reviews the petition and, if approved, forwards it to the Department of State's National Visa Center.
  • The case is sent to the US embassy or consulate handling the fiancé(e)'s application.
  • The fiancé(e) completes the online nonimmigrant visa application (DS-160), pays the visa fee, and gathers required documents.
  • The fiancé(e) attends a visa interview, including a required medical examination.
  • If issued, the fiancé(e) travels to the US and must marry the petitioner within 90 days.

After you marry: adjusting status

The K-1 visa allows a single entry and a 90-day stay for the purpose of marrying the petitioner. After the marriage takes place, the foreign spouse applies to adjust status to lawful permanent resident by filing Form I-485 with USCIS.

Because the initial green card is based on a recent marriage, it is normally granted on a conditional basis, and the couple must later apply to remove those conditions to obtain permanent status. If the couple does not marry within 90 days, the K-1 status cannot be extended and the fiancé(e) is expected to leave the United States.

Bringing children (K-2)

Unmarried children under 21 of the K-1 fiancé(e) may qualify for K-2 visas based on the same approved I-129F petition. The children must be listed on the petition. K-2 children can generally travel with or follow the K-1 parent and later apply to adjust status alongside the parent once the marriage has taken place.

Frequently asked questions

  • The K-1 status is strictly tied to marrying the petitioner within 90 days of entry. It cannot be extended, and the fiancé(e) is expected to leave the United States if the marriage does not take place. The couple would then need to consider other immigration options.
