To file Form I-129F, a U.S. citizen mails the completed petition, a $675 filing fee, and supporting evidence to the USCIS Dallas Lockbox. The evidence must show that you and your fiancé(e) met in person within the last two years, that you both intend to marry within 90 days of their arrival in the United States, and that you are each legally free to marry. Once approved, USCIS forwards the petition to the Department of State so your fiancé(e) can apply for a K-1 visa at a U.S. consulate.
Who Can File
Only U.S. citizens can file Form I-129F. Green card holders are not eligible and must use a different family-based path. Federal law requires you to show three things: the couple met in person within the two years before filing, both parties genuinely intend to marry, and both are legally able to enter a valid marriage within 90 days of the fiancé(e)’s admission.1Office of the Law Revision Counsel. 8 USC 1184 – Admission of Nonimmigrants “Legally able” means every prior marriage on either side has already ended by divorce, annulment, or the death of the former spouse.
The In-Person Meeting
The two-year, in-person meeting is where most petitions run into trouble. Flight itineraries alone aren’t enough. USCIS wants a combination of boarding passes, passport stamps, hotel receipts, and dated photos of the two of you together.2U.S. Citizenship and Immigration Services. Visas for Fiancees of US Citizens The more varied the evidence, the smoother the review.
The Secretary of Homeland Security can waive the meeting requirement, but only in narrow circumstances: when meeting would violate strict, long-established customs of the fiancé(e)’s culture, or when meeting would cause extreme hardship to you as the petitioner. Extreme hardship has to go well past inconvenience or cost. Think serious medical conditions, active military deployment in a conflict zone, or a government-imposed travel ban. Petitions relying on a waiver draw heavier scrutiny.
IMBRA Disclosures and Prior-Petition Limits
The International Marriage Broker Regulation Act adds disclosures many petitioners don’t see coming. Part 3 of the form asks you to report any criminal convictions or restraining orders involving domestic violence, sexual assault, child abuse, and other violent crimes.1Office of the Law Revision Counsel. 8 USC 1184 – Admission of Nonimmigrants USCIS shares this information with the foreign fiancé(e) so they can make an informed decision.3U.S. Citizenship and Immigration Services. International Marriage Broker Regulation Act Pamphlet Not disclosing a qualifying conviction can result in denial and potential criminal liability.
IMBRA also caps how many fiancé(e) petitions you can file without a waiver. You need one if you have previously filed Form I-129F for two or more different fiancé(e)s, or if fewer than two years have passed since the filing date of your last approved petition.4U.S. Citizenship and Immigration Services. Form I-129F Instructions The waiver isn’t automatic; USCIS decides case by case whether granting it serves the beneficiary’s interests.
Documents to Gather Before You File
Missing evidence is one of the most common causes of delay and Requests for Evidence. A complete package includes:
- Proof of your U.S. citizenship: a copy of your birth certificate issued by a civil authority, a valid U.S. passport, a naturalization certificate, or a consular report of birth abroad.
- One color passport-style photo of you and one of your fiancé(e), taken within 30 days of filing, on a white or off-white background, printed on glossy thin paper.4U.S. Citizenship and Immigration Services. Form I-129F Instructions
- Proof that every prior marriage has ended: final divorce decrees, annulment orders, or death certificates, for both of you.
- Evidence of the in-person meeting within the last two years: flight records, passport entry stamps, hotel receipts, and dated photos.
- A signed statement from each of you confirming the intent to marry within 90 days of the fiancé(e)’s admission, with a brief account of how you met and your wedding plans.
Any document not in English needs a certified English translation. The translator must certify in writing that they are competent to translate and that the translation is accurate. Costs typically run $20 to $95 per document depending on language and length.
If your fiancé(e) has unmarried children under 21, list each one in Part 2 of the form with full name, date of birth, and country of birth. They can enter on derivative K-2 visas without a separate petition, but each child goes through their own consular interview and medical exam abroad.
Filling Out the Form
Download the current edition of Form I-129F from uscis.gov/i-129f. USCIS rejects filings on outdated editions, and you don’t get credit for the earlier filing date.
Part 1 covers you as the petitioner: full legal name, any previous names, Social Security number, date of birth, and a five-year history of residential addresses and employers. Part 2 covers your fiancé(e) and any of their children: foreign address, biographical details, and children’s information. Every name has to match the spelling on passports and government-issued identity documents exactly. A single-letter discrepancy can trigger delays.
Part 3 is the IMBRA disclosure. Fill every field on the form; enter “N/A” or “None” where a question doesn’t apply. A handwritten signature is required. Typed or stamped signatures are not accepted, and an unsigned petition gets rejected and returned without a receipt date.
The Filing Fee
The filing fee for Form I-129F is $675.5U.S. Citizenship and Immigration Services. Form G-1055, Fee Schedule DHS adjusts fees periodically, so confirm the amount on the USCIS fee schedule before mailing.
Pay by personal check, cashier’s check, or money order made out to “U.S. Department of Homeland Security.” To pay by credit, debit, or prepaid card, complete Form G-1450 and place it on top of your petition package.6U.S. Citizenship and Immigration Services. G-1450, Authorization for Credit Card Transactions If a check bounces or the fee amount is wrong, USCIS returns the entire package without assigning a receipt date, and you lose whatever time passed since the original mailing.

G-1145, E-Notification of Application/Petition Acceptance The notification includes your receipt number, so you can start checking status online right away.
What Happens After You File
Once the Lockbox accepts the petition, USCIS mails you Form I-797C, Notice of Action, as your official receipt.9U.S. Citizenship and Immigration Services. Form I-797C, Notice of Action The receipt number lets you track your case at egov.uscis.gov/casestatus. Keep the notice; you will need the number throughout the process.
If USCIS finds the evidence incomplete, it issues a Request for Evidence specifying what’s missing. The case pauses until you respond. Miss the deadline and USCIS can deny the petition, either as abandoned or on the merits of what’s already in the file.10U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 1 Part E Chapter 6 – Evidence RFE deadlines are firm.
Processing times shift with USCIS workloads. Check the USCIS processing times page for current estimates. Plan on several months at a minimum, and hold off on calling USCIS unless your case has exceeded the posted time; earlier inquiries won’t speed anything up.
What Comes After Approval
Approval of Form I-129F is only the first step. USCIS forwards the file to the National Visa Center, which sends it to the U.S. embassy or consulate in the beneficiary’s home country. The consulate schedules the K-1 visa interview, and at that stage the beneficiary pays a $265 nonrefundable visa application fee to the Department of State11U.S. Department of State. Fees for Visa Services and completes a medical examination with an embassy-approved panel physician.12U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 8 Part B Chapter 3 – Applicability of Medical Examination and Vaccination Requirements Medical exam costs generally run $200 to $500 depending on the country. Before the interview, you file Form I-134, Declaration of Financial Support, to show you can support your fiancé(e) during the temporary stay.
Once the fiancé(e) enters on the K-1, a strict 90-day clock starts. The couple has to legally marry within those 90 days, and there are no extensions. If the marriage doesn’t happen, the fiancé(e) has no basis to remain and must depart. Overstaying can trigger removal proceedings and three- or ten-year bars to reentry, depending on the length of unlawful presence. A K-1 holder can only adjust status based on marriage to the petitioner who filed the original I-129F; marrying someone else doesn’t qualify. After the wedding, the new spouse files Form I-485 to apply for a green card, along with Form I-864, the binding Affidavit of Support.
