Form I-129F in short
Form I-129F is the petition a U.S. citizen files to bring a foreign fiancé(e) to the United States on a K-1 visa so they can marry. It is also used to bring a foreign spouse on a K-3 visa while a Form I-130 is pending. Eligible children of the beneficiary can be included without a separate petition.

Common mistakes to avoid
- Leaving out fields USCIS lists as rejection triggers: the classification sought, your family name, mailing address and date of birth, and the beneficiary's classification, family name and date of birth.
- Not signing the petition.
- Not including proof of in-person meeting within two years of filing for a K-1 petition, or an explanation for an exemption.
- Forgetting a passport-style photo of yourself and of your fiancé(e), taken within 30 days of filing.
- Not proving that prior marriages ended, with a divorce decree, annulment or death certificate.
- Leaving out criminal history or protection orders, or not asking for a multiple filer waiver when required.
- Sending non-paper items such as thumb drives or DVDs, which USCIS will not accept.
- Filing a K-3 petition without the Form I-130 receipt notice (unless filing both together) and the marriage certificate.
Questions about Form I-129F
Can a Green Card holder file Form I-129F?
No. The form is for U.S. citizens petitioning for a fiancé(e) or spouse.
Do I need separate petitions for my fiancé(e)'s children?
No. Unmarried children under 21 of a K-1 or K-3 beneficiary can apply for K-2 or K-4 visas based on the same petition.
What if we have not met in person in the last two years?
You can ask for an exemption if meeting would violate strict and long-established customs of your fiancé(e)'s culture, or would be an extreme hardship for you. Attach evidence.
Can I file Form I-129F online?
USCIS lists a mailing address at the Dallas lockbox. The form is not on the USCIS list of forms available to file online as of 2026-10-25.
What is the filing fee?
$675. There is no fee for a K-3 petition based on a Form I-130 you filed.
Can I withdraw the petition?
Yes, with a signed written request to USCIS. If it is already approved, contact the Department of State. Once the beneficiary is admitted in K status, you can no longer withdraw it.
