Form I-129F guide: Petition for Alien Fiancé(e)

Wang Law Firm, LLC · David Wang, Managing Attorney · Attorney-reviewed · Updated October 2026

The official name of I-129F is Form I-129F, Petition for Alien Fiancé(e), and it is handled by U.S. Citizenship and Immigration Services (USCIS). It is the first step for a U.S. citizen to obtain a K-1 nonimmigrant visa for a fiancé(e) who is outside the United States; the same form is also used to obtain a K-3 visa for a spouse (the children correspond to K-2 and K-4).

In the overall process, USCIS decides the I-129F; after approval the case moves to the Department of State's National Visa Center (NVC) and then to the U.S. embassy or consulate in the beneficiary's country, which interviews the beneficiary and issues the K-1 visa. After entering on a K-1, the beneficiary must marry the petitioner within 90 days and then file I-485 inside the United States to apply for a green card. For an overview of the K-1 visa and how it compares with marriage-based immigration, see K-1 fiancé(e) visa.

At a glance

Who can file and when it doesn't apply

K-1 fiancé(e)

• The petitioner must be a U.S. citizen;
• Both parties are legally free to marry: unmarried, or any prior marriage legally ended by divorce, annulment or the death of the spouse;
• Both genuinely intend to marry within 90 days after the beneficiary's entry;
• The two have met in person at least once within the 2 years before filing (a waiver can be requested; see below);
• The beneficiary is outside the United States (K-1 is a visa for entry).

K-3 spouse

A U.S. citizen who has already filed an I-130 for a foreign spouse can, while waiting, separately file I-129F for a K-3 nonimmigrant visa so the spouse can come to the United States and wait here. In practice, if the I-130 is approved before the K-3 process is complete, the NVC generally closes the K-3 case and processes the immigrant visa (IR-1/CR-1) directly, so K-3 is now rarely used. K-3 children are K-4.

Situations where it doesn't apply

• The petitioner is a green card holder: cannot file I-129F and can only file I-130 (F2A) after marrying;
• The couple is already married: K-1 is no longer available; use I-130 (or K-3);
• The beneficiary is already in the United States: K-1 is designed for beneficiaries abroad, and couples who marry in the United States generally go directly through I-130 + I-485; see Marriage green cards;
• The couple cannot yet legally marry (for example, one party's divorce is not yet final).

The beneficiary's children (K-2)

The beneficiary's unmarried children under 21 can enter with or after the beneficiary on K-2 visas without a separate I-129F, but they must be listed on the form. After entry, the children also adjust status through I-485; the child's age, when they enter and when the I-485 is filed all affect eligibility, so pay attention to these.

Legal basis and eligibility

• K visa categories: Immigration and Nationality Act (INA) section 101(a)(15)(K) (K-1 fiancé(e), K-2 child, K-3 spouse, K-4 child).
• Requirements for a fiancé(e) petition: INA section 214(d); regulations at 8 CFR 214.2(k). These include the 2-year meeting requirement and marriage within 90 days after entry.
• Waiver of the meeting requirement: 8 CFR 214.2(k)(2) — it can be waived where meeting would cause extreme hardship to the petitioner or would violate strict and long-established customs of the beneficiary's culture.
• International Marriage Broker Regulation Act (IMBRA): incorporated in INA section 214(d) and related provisions, it requires the petitioner to disclose certain criminal history and limits multiple K-1 filings (see below).
• Adam Walsh Act: if the petitioner has been convicted of certain specified offenses against minors, the petition cannot be approved unless the Department of Homeland Security determines that the petitioner poses no risk to the beneficiary.
• Limits after K-1 entry: under INA sections 245(d) and 248, K-1/K-2 holders can adjust status only on the basis of the marriage to that petitioner; they cannot change to another nonimmigrant status or adjust status in the United States through any other route.

IMBRA: criminal record disclosure and multiple-filing limits

• Criminal record disclosure: the petitioner must truthfully answer whether they have ever been arrested for or convicted of specified crimes such as domestic violence, sexual assault, child abuse, homicide, assault, stalking or unlawful restraint, or multiple alcohol- or controlled-substance-related offenses, and whether there are protection orders, attaching the relevant court and police records. This information is disclosed to the beneficiary through the embassy or consulate, and the beneficiary also receives an information pamphlet about their rights.
• Multiple-filing limits: if the petitioner has previously filed two or more K-1 petitions, or had a K-1 petition approved within the 2 years before this filing, the petitioner must request a waiver in the petition, explaining the reasons and attaching evidence.
• Petitioners with a violent criminal record: where the petitioner has a violent criminal record and also triggers the multiple-filing limits, the waiver standard is stricter and a waiver is generally granted only in extraordinary circumstances; follow USCIS rules for details.
• Use of an international marriage broker: you must state truthfully whether the couple met through an international marriage broker and provide the broker's information.

Recent changes

• Form edition updates: USCIS has updated family-based forms several times in recent years, and older editions are rejected once the transition period ends. Before filing, check the current I-129F edition (Edition Date) on the official page and whether older editions are accepted.
• Payment methods: starting October 28, 2025, USCIS generally switched to electronic payment for paper filings (for example, card payment with G-1450 or a bank account debit with G-1650); exceptions are as stated in the official guidance.
• Country-specific limits on visa issuance: in 2025–2026 the United States restricted visa issuance for nationals of certain countries, and the policies have changed often. An approved I-129F does not guarantee a visa; check before filing whether the beneficiary's nationality is affected.

Filling it out

Information about the petitioner (U.S. citizen)

• Visa classification: at the start, check whether you are filing for K-1 or K-3. For K-3, also provide information about the I-130 already filed.
• Name, addresses and employment: list other names used; you usually need to give your address and employment history for the past 5 years, continuous and without gaps.
• Marital history: list every prior marriage, including the spouse's name and the date it ended, and attach proof that it ended.
• Citizenship: through birth, naturalization or parents; if naturalized, give the certificate number.
• Prior I-129F filings: whether you have ever filed I-129F for anyone, with filing dates, beneficiaries and outcomes. This question ties directly to the IMBRA multiple-filing limits; answer truthfully.
• Children: information about the petitioner's own children under 18 (IMBRA-related).

Information about the beneficiary

• The beneficiary's name, birth information, marital history, and whether they have been to the United States before and their entry records;
• The beneficiary's children under 21 (K-2);
• The beneficiary's past addresses and employment history, and parents' information;
• The beneficiary's name and address written in their native script;
• The relationship: whether the two are related by blood (for example, cousins; whether they can legally marry depends on the law of the place of marriage); whether they met in person within 2 years, and when and under what circumstances; if requesting a waiver, explain why;
• Whether they met through an international marriage broker;
• Which U.S. embassy or consulate the beneficiary will apply at: generally the one in the beneficiary's country of nationality or lawful residence; fill this in accurately.

Other information (IMBRA criminal history questions)

Answer each item on whether there are protection orders and whether you have been arrested for or convicted of specified crimes. Even if a case was dismissed or a record sealed, answer truthfully and attach the court documents, consulting an attorney first if needed. Concealing a record can lead to denial and may constitute misrepresentation.

Biographic information, statement and signature

• The petitioner's height, weight and other biographic information;
• The petitioner must sign by hand; if there is an interpreter or preparer, complete the corresponding sections;
• Anything that does not fit goes on the additional information page.

Evidence and supporting documents

• Proof of the petitioner's U.S. citizenship: U.S. birth certificate, valid U.S. passport, Certificate of Naturalization or Certificate of Citizenship, etc.;
• Both parties' legal ability to marry: proof that prior marriages ended (divorce decrees, annulment decrees, death certificates of former spouses);
• Evidence of meeting within 2 years: airline tickets and boarding passes, passport entry and exit stamps, hotel records, photos together, itineraries, etc.; if requesting a waiver, attach an explanation and evidence;
• Statements of intent to marry: a statement signed by each party saying they intend to marry within 90 days after the beneficiary's entry; evidence of wedding planning (such as a venue booking) can be added as support;
• Evidence of the relationship: communications and correspondence, choosing representative samples;
• Photos: passport-style photos of both parties as required by the instructions;
• IMBRA documents: if there are criminal or protection order records, certified court and police documents; if the multiple-filing limits apply, the waiver request and evidence;
• Proof of name change: if a name has changed;
• If you have an attorney, include G-28; if you want electronic notification, you can include G-1145.

Chinese-language documents (for example, a divorce certificate, a divorce judgment, or the beneficiary's notarial birth certificate) must come with a complete English translation and a translator's certification; see Translation requirements. At the consular interview stage, the originals must also be prepared according to the U.S. Department of State's published civil document list for China (for example, for a beneficiary from China).

How to file and fees

• Filing address: generally mailed on paper to the USCIS lockbox designated for it; rely on the official I-129F page for the address.
• Fees: rely on the USCIS fee schedule (G-1055); K-2 children do not need a separate I-129F. Consular visa application fees, medical exam fees and the like come later and are paid separately. See How to check fees and processing times.

What happens after filing

1. Receipt notice: USCIS issues an I-797C receipt, and you can check status online; see Checking your USCIS case status.
2. Request for Evidence (RFE): insufficient evidence of meeting and incomplete IMBRA documents are common reasons; for how to respond, see How to respond to an RFE.
3. Approval: after approval the case goes to the NVC and then to the embassy or consulate where the beneficiary will apply. An approved I-129F is generally valid for 4 months after approval for the consulate to act on, and the consulate can extend the validity as appropriate.
4. Consular stage: the beneficiary completes DS-160, has the immigration medical exam (see Immigration medical exam), prepares civil documents and proof of financial support (consulates usually ask the petitioner to submit I-134), and attends the interview.
5. Entry and marriage: the beneficiary enters on the K-1 visa and must marry the petitioner within 90 days.
6. Adjustment of status: after the marriage, file I-485; at this point the petitioner must submit a legally binding I-864 Affidavit of Support. Work authorization and a travel document can be requested at the same time. If approved when the marriage is less than 2 years old, the green card is conditional, and I-751 must be filed later.

Check processing times on the USCIS processing times page; consular interview scheduling is as published by the Department of State and each embassy or consulate.

Common reasons for denial and options after a denial

• Unable to prove an in-person meeting within 2 years, and not eligible for a waiver;
• One party's prior marriage has not legally ended;
• Doubts about whether the relationship is genuine;
• Incomplete criminal record or multiple-filing waiver documents required by IMBRA;
• Failure to respond to an RFE.

After an I-129F denial, the most common approach is to refile with stronger evidence; whether a motion or appeal (I-290B) is available depends on the instructions in the denial notice. In addition, even after the I-129F is approved, the consulate can still refuse the visa at the interview or return the case to USCIS for review. If the couple has since married, they can also switch to the I-130 immigrant visa route.

I-129F compared with I-130

Which route fits better depends on whether the couple is already married, where the wedding will be, arrangements during the wait, and processing times at the time. For a detailed K-1 comparison, see K-1 fiancé(e) visa.
