Letter of intent to marry for the K-1 visa interview: USCIS rules, signature requirements and what the officer checks

Preparing for your K-1 visa interview? Both you and your partner must sign statements of intent to marry proving you are legally free to wed and plan to marry within 90 days of U.S. entry, according to USCIS's Form I-129F instructions. At the embassy interview, a Department of State officer checks your statements and wedding plans to decide if your relationship is bona fide, or refuses the visa and returns the petition to USCIS.

What is the letter of intent to marry for a K-1 visa?

A letter of intent to marry is a signed written statement confirming that you and your partner are legally able to marry and plan to wed within 90 days of the foreign fiancé(e)'s admission to the United States on a K-1 nonimmigrant visa.

USCIS's Form I-129F webpage and instructions state that K-1 petitioners must submit evidence that both partners have a bona fide intention to marry and intend to marry within 90 days of entry. USCIS's optional filing checklist for Form I-129F names "proof or original statements of intent to marry from both you and your fiancé(e)" as the standard item to include.

The legal requirement behind the letter has three parts on USCIS's fiancé(e) visa guidance page:

• Both partners intend to marry each other within 90 days of the fiancé(e) entering the U.S. as a K-1 nonimmigrant.
• The planned marriage is valid, meaning both partners have a bona fide intent to build a life together and the marriage is not solely to get an immigration benefit.
• Both partners are legally free to marry in the United States, with any prior marriages already ended by divorce, death or annulment.

How the statement of intent to marry fits into the K-1 process (USCIS Form I-129F instructions and fiancé(e) visa guidance, as of November 2026)

What USCIS requires in the statements and signatures

The Form I-129F instructions (edition 01/20/25) say that evidence of your intention to marry within 90 days of entry "may include statements of intent to marry signed by both you and your fiancé(e) or any other evidence that establishes, by a preponderance of the evidence, your mutual intention." Preparing one statement signed by the U.S. citizen petitioner and one signed by the foreign fiancé(e) beneficiary satisfies USCIS's checklist.

While USCIS does not publish a fill-in-the-blank form for this letter, matching the Form I-129F General Instructions (citing 8 CFR 103.2(a)(7)(ii)(A)) means each partner's letter must follow these content and signature rules:

• Full names and addresses: The signer's full legal name and current address, matching Part 1 (petitioner) or Part 2 (beneficiary) of Form I-129F, plus the other partner's full legal name.
• Recipient header and case numbers: Addressed to USCIS for the Form I-129F filing, or to the Consular Section of the U.S. Embassy or Consulate for the interview, with your USCIS Receipt Number and NVC Case Number once assigned.
• Legal ability and 90-day declaration: A clear statement that the signer is legally free to marry, has a bona fide intention to build a life together, and promises to marry the other partner within 90 days of the foreign fiancé(e)'s admission as a K-1 nonimmigrant.
• Handwritten ink signature required: USCIS will not accept a stamped or typewritten name in place of any signature. Sign the original document by hand in ink and date it.
• Scans and photocopies count for USCIS filing: USCIS considers a photocopied, faxed or scanned copy of an original document with a handwritten ink signature valid for filing. Submit legible photocopies unless an original is specifically requested, as USCIS may destroy unrequested originals.
• Foreign language translation rules: Any document in a foreign language must include a full English translation. The translator must sign a certification stating that the English translation is complete and accurate and that they are competent to translate from the foreign language into English, with the translator's printed name, signature, date and contact information.

Example structure for petitioner and beneficiary statements

Below are structural block templates written by our team for the K-1 consular interview stage. Each block outlines in second person the exact fields, case identifiers and legal declarations to include.

Updating your letters and how the officer checks your intent at the interview

When USCIS approves Form I-129F, it recognizes the claimed fiancé(e) relationship and sends the approved petition to the Department of State's National Visa Center (NVC), which forwards it to the U.S. Embassy or consulate where your fiancé(e) lives. Because months pass between Step 1 and Step 2, both partners should sign and date fresh statements addressed to the Consular Section of the U.S. Embassy or Consulate once the interview is scheduled. Check your embassy's interview instructions to confirm whether the officer accepts a printed scan of the petitioner's freshly signed statement or asks for the physical wet-ink original.

Approval of Form I-129F by USCIS does not guarantee the visa. At the interview, your fiancé(e) brings the required forms and documents, and the Department of State consular officer independently decides whether your fiancé(e) qualifies for the K-1 visa and whether your relationship and intent to marry are bona fide.

What happens if the officer doubts your intent: USCIS states that if the consular officer does not find the relationship to be bona fide, the Department of State will not issue the K-1 visa and will return the Form I-129F to USCIS. Generally, if the Department of State returns a Form I-129F after it has expired, USCIS allows it to remain expired, though the petitioner may file a new Form I-129F. Note that under the Form I-129F instructions, USCIS may also request earlier in the process that the petitioner appear at a USCIS office for an interview and provide biometrics.

What the consular officer may ask about your intent to marry

At the K-1 visa interview, the consular officer compares your spoken answers against the Form I-129F petition, your signed statements of intent to marry, and your supporting records. Review the exact facts on your forms so you can answer honestly without reciting a script.

• "When and where did you and your fiancé(e) meet in person?" What it checks: That you met in person within the 2 years before filing Form I-129F (unless you requested a waiver based on extreme hardship or strict cultural custom) and that your spoken timeline matches Item Numbers 53 and 54 in Part 2 of the petition. What to have ready: Exact dates, cities, flight records, passport entry stamps and photos from your visits.
• "What are your plans to get married within 90 days of arriving in the United States, and how have your plans developed since you filed Form I-129F?" What it checks: Consular officers cross-examine your spoken answers against your signed letters of intent to verify that your 90-day promise is backed by a practical plan to build a life together, including whether you plan a civil courthouse ceremony or a religious wedding inside the 90-day window. What to have ready: The U.S. city and state where you will live (matching Part 2, Item Numbers 45.a to 46 on Form I-129F), your ceremony plan, and proof of arrangements such as venue or officiant inquiries.
• "Have either you or your fiancé(e) been married before, and how did those marriages end?" What it checks: That both partners are legally free to marry and know each other's family history. What to have ready: The names of any prior spouses, the dates those marriages ended (matching Part 1, Item Numbers 37 to 39 and Part 2, Item Numbers 34 to 36), and the civil divorce decrees, annulment orders or death certificates.
• "Did you meet through an International Marriage Broker, and do you know about your fiancé(e)'s background?" What it checks: Compliance with the International Marriage Broker Regulation Act (IMBRA). Under the Form I-129F instructions, USCIS shares any protection orders or criminal history from Part 3 of the petition with the Department of State for disclosure to the beneficiary at the interview. What to have ready: Honest knowledge of how you met (and the signed IMB consent form if applicable) plus any criminal or marital history disclosed on the petition.

Checklist of supporting evidence required alongside your letters

A signed statement of intent to marry does not replace proof that you met in person or are legally free to marry. Based on USCIS's Form I-129F instructions and fiancé(e) visa guidance, our team organized this checklist of supporting proof:

• Supporting proof of your 90-day wedding plans for the interview: Email inquiries or reservations with a wedding venue or civil courthouse, correspondence with a marriage officiant, engagement or wedding ring receipts, tentative guest lists, and plans for moving to the U.S. address in Part 2, Item Numbers 45.a to 46 of Form I-129F.
• Proof of the petitioner's U.S. citizenship: A copy of a U.S. birth certificate issued by a civil authority, naturalization or citizenship certificate, Form FS-240 (Consular Report of Birth Abroad), an unexpired U.S. passport or passport card issued with at least a 5-year validity period, or a U.S. consular officer's statement verifying citizenship.
• Proof that all prior marriages ended legally: Copies of final divorce decrees, annulment orders or death certificates issued by a civil authority for every prior marriage of either partner.
• Proof of meeting in person within 2 years before filing Form I-129F: Written statements describing your meeting, airline tickets, passport pages and photos showing you were in each other's physical presence (or evidence supporting an extreme hardship or strict cultural custom waiver).
• Other required Form I-129F packet items: One 2-by-2-inch color passport-style photograph of the petitioner and one of the beneficiary taken within 30 days of filing, proof of any legal name change, the beneficiary's CBP Form I-94 Arrival-Departure Record number and expiration date if ever issued, and any required IMBRA consent forms, Part 3 criminal disposition records or multiple-filer waiver requests.

What happens after the K-1 interview and the 90-day marriage rule

If the consular officer grants the K-1 visa, it is valid for up to 6 months for a single entry into the United States. A U.S. Customs and Border Protection (CBP) officer at the port of entry makes the final decision to admit your fiancé(e), starting the 90-day clock promised in your letter of intent.

Marrying within 90 days and filing Form I-485: After you marry within 90 days, your new spouse (and any qualifying unmarried K-2 children under 21) can apply for a Green Card by filing Form I-485 and apply for work authorization on Form I-765. Spouses married less than two years when Form I-485 is approved receive conditional permanent resident status valid for 2 years.

What happens if you do not marry within 90 days: K-1 and K-2 status automatically expires after 90 days and cannot be extended. USCIS's change-of-status rules also prohibit K nonimmigrants from changing to another nonimmigrant status inside the United States (except for T or U nonimmigrant filings). If you do not marry within 90 days, your fiancé(e) and any K-2 children must leave the United States or face removal. If you marry after the 90-day period, the U.S. citizen must file Form I-130 (Petition for Alien Relative) instead.

Practice example

What are your wedding plans once you arrive in the United States, and how do you know you will marry within 90 days?

A strong, honest answer gives the specific, practical details of your plan to marry within the 90-day window without sounding rehearsed. State the city and state where you will live with your U.S. citizen fiancé(e), making sure the address matches Part 2, Item Numbers 45.a to 46 of your Form I-129F petition. Explain the type of ceremony you have planned for those first 90 days, whether that is a civil courthouse marriage right after arrival followed by a larger reception later, or a religious ceremony you have already started organizing. Even if you cannot lock in an exact wedding date until the visa is issued, be ready to name the month or timeframe you are aiming for, who will attend, and any steps you have already taken together. Bring your signed statements of intent to marry and any supporting proof of your arrangements, as listed in the checklist above, so you can hand them over if the officer asks.

The consular officer is checking that your signed statement of intent to marry reflects a bona fide intention to build a life together within 90 days of entry, not a marriage solely for an immigration benefit. Giving concrete details that match your Form I-129F shows your plan is real and active.
