Form I-129F, Explained

A guide to the processing time, cost, and requirements to file the “Petition for Alien Fiancé(e)” form

What is Form I-129F?

Form I-129F (“Petition for Alien Fiancé(e)”) is the first step towards a K-1 visa for the fiancé of a U.S. citizen, or a K-3 visa for the spouse of a U.S. citizen (note the K-3 visa is rarely issued). If you’re engaged to a U.S. citizen, you can use the K-1 visa to enter the U.S. if you plan on getting married within 90 days of your arrival.

Form I-129F to Green Card Timeline

Once your Form I-129F petition has been approved, the sponsored fiancé will then need to apply for their visa, attend an interview, and enter the U.S. before they can apply for a green card.

For more, Boundless has put together a guide on timelines for each phase of the K-1 process.

Once the K-1 visa is approved, the sponsored fiancé will need to enter the U.S. within six months, and the couple must get married within 90 days. The sponsored fiancé — now considered the spouse of a U.S. citizen — will then need to file Form I-485 (adjustment of status) so they can start their spousal green card application, which can take anywhere from a few months to a few years to process.

Expedited Processing for Form I-129F

Premium processing is not available for Form I-129F, but you may be able to make an expedite request through the USCIS Contact Center with your 13-digit USCIS case receipt number. USCIS considers each request on a case-by-case basis, and you will need to have documentation to support the reason you’re asking for expedited processing.

Form I-129F Cost

The government filing fee for Form I-129F is $675. If you’re filing Form I-129F to petition for the spouse of a U.S. citizen to enter on a K-3 visa however, then that fee is waived.

Important Update (January 31, 2024):

The cost to file Form I-129F will increase from $675 to $675 on April 1, 2024. Learn more about USCIS’ upcoming fee changes here and get started on your application with Boundless now to avoid paying higher fees.

Who can file Form I-129F?

You can file Form I-129F if you are a U.S. citizen petitioning for either your fiancé to enter the U.S. for your marriage, and you have met your fiancé in person in the last two years. You can also file this form if you’re a U.S. citizen petitioning for your spouse to enter the U.S. and USCIS has already approved Form I-130 (“Petition for Alien Relative”) for them to start their green card application (although learn more about why this option is rarely used).

Who cannot file Form I-129F?

Because only U.S. citizens can file Form I-129F, if you are a green card holder, you won’t be able to file Form I-129F for your fiancé or spouse. If you are a green card holder who is already married, you can petition for your spouse’s entry as the first step in the green card process.

Supporting Documents

When you file Form I-129F, you will need to include supporting documents to prove your identity and your relationship with your fiancé or spouse. These documents may include:

  • Proof that you are a U.S. citizen, either through a copy of your birth certificate, a certificate of citizenship or naturalization, a copy of an unexpired passport.
  • One color photograph, passport-style, of both yourself and your fiancé, taken within 30 days of filing.
  • Proof of legal name change if you’ve changed your name in the past.
  • If you or your fiancé have previously been married, you’ll also need to show proof the marriage has been terminated, for example with a divorce decree or annulment order.

If you’re petitioning for your fiancé to enter on a K-1 visa, you should also include the following:

  • Proof that you and your fiancé intend to marry within 90 days after they arrive in the U.S.
  • Proof you have met each other in-person within two years of filing Form I-129F. If you haven’t met each other in-person, you’ll need to send proof of why you haven’t been able to meet, for example, if meeting each other would have violated strict, long-established cultural customs.

If you’re petitioning for your spouse to enter under K-3 status, you should include the following:
