If you are a U.S. citizen bringing your fiancé(e) to the United States on a K-1 visa, you gather documents in two stages.
First, the U.S. citizen files a fiancé petition with USCIS. That petition needs proof of four things:
- You are a U.S. citizen.
- You are both free to marry.
- You have met in person.
- You truly plan to marry.
Second, your fiancé(e) brings a new set of documents to the visa interview at a U.S. embassy or consulate abroad. These include a passport, civil records, medical exam results and proof of financial support.
Below is a plain-English checklist of what is usually needed at each step. This is general information, not legal advice. Every case is different, so if your situation has any twists, talk with an attorney before you file.
Stage One: Documents for the Fiancé Petition
The U.S. citizen partner files the petition. Its job is to show USCIS that your relationship is real and that you are legally able to marry. Plan to include:
- Proof of U.S. citizenship. A copy of your U.S. passport, U.S. birth certificate, or certificate of naturalization or citizenship.
- Proof you are both free to marry. If either of you was married before, include divorce decrees, annulment records or death certificates showing each prior marriage ended.
- Proof you have met in person. Good examples are photos of you together, travel itineraries, boarding passes, hotel receipts and passport stamps. The law generally requires an in-person meeting. There are only narrow exceptions.
- Proof you intend to marry. Include a signed statement from each of you about your relationship and wedding plans. Items like a ring receipt, venue booking or invitations also help.
- Passport-style photos of each of you.
- Name change records, if either of you has used a different legal name.
Strong relationship evidence matters. Call logs, messages, letters and photos taken over time help tell your story. Choose quality over volume. A well-organized sample is more useful than hundreds of pages of screenshots.
Stage Two: Documents for the Visa Interview Abroad
Once USCIS approves the petition, the case moves to the National Visa Center. From there it goes to the U.S. embassy or consulate in your fiancé(e)’s country. Your fiancé(e) completes an online visa application and prepares for an interview. Common documents at this stage include:
- A valid passport
- A birth certificate
- Prior marriage and divorce records, if any
- Police certificates from the places the embassy asks for
- Medical exam results from an embassy-approved doctor, along with vaccination records
- Passport-style photos
- Updated evidence of your relationship
- Financial support documents from the U.S. citizen, such as an affidavit of support, recent tax returns and proof of current income
Each embassy can have its own instructions, so read the interview letter carefully. For a general overview of how visa applications work, see our guide on how to apply for a visa to the USA.
Tips for a Smoother Document Package
- Translate foreign documents. Any document that is not in English needs a full, certified English translation.
- Keep details consistent. Names, dates and addresses should match across every form and record. Small differences can lead to questions or delays.
- Send copies, not originals, unless you are told to provide originals. Bring your originals to the interview.
- Use current forms. USCIS and the State Department update their forms and fees. Download them fresh from official government sources.
- Organize with labels. A clear index and tabbed sections make it easier for an officer to follow your case.
Common Mistakes That Slow Down Fiancé Visa Cases
Many delays come from problems you can prevent, such as:
- Missing proof that a prior marriage ended
- Records that were never translated
- Thin evidence of meeting in person
- Financial documents that do not match what was written on the forms
Any of these can lead to a request for more evidence, which can add weeks or months to your case. Careful preparation before filing is one of the simplest ways to avoid that.
What Comes After the Wedding
The K-1 visa is a first step. After your fiancé(e) arrives, you must marry within the time the visa allows. The next stage is usually applying for a green card from inside the United States. That application needs its own set of documents. Learn more on our marriage green card page.
If the green card is issued on a conditional basis, you will later need to remove the conditions on your green card.

Frequently Asked Questions
Who files the documents for a K-1 fiancé visa?
The U.S. citizen files the fiancé petition with USCIS. After it is approved, the foreign fiancé(e) submits a visa application and supporting documents to the U.S. embassy or consulate in their country and attends an interview.
Do we need proof that we met in person?
In general, yes. The law usually requires an in-person meeting, and photos, travel records and receipts help show it happened. There are only narrow exceptions. If you have not met in person, speak with an attorney before you file.
Do foreign documents need to be translated?
Yes. Any document that is not in English should come with a complete, certified English translation. Missing translations are a common reason for delays.
What financial documents does the U.S. citizen need?
Expect to show you can support your fiancé(e). This is usually done with an affidavit of support, recent tax returns and proof of current income. If your income may not be enough, ask an attorney about your options before the interview.
