K-1 Fiancé Visa Process: A Step-By-Step Guide

A K-1 visa allows a U.S. citizen to bring their foreign national fiancé(e) to the U.S. before marriage. Once in the U.S., the marriage needs to be completed within 90 days. Then the K-1 visa holder can file Form I-485 to apply for a Green Card.

The K-1 visa is one of the more straightforward immigration processes, and it can be broken down into a few clear steps. The approval rates for K-1 visas also hit a 10-year high in 2024. However, the application does require a lot of documentation. U.S. Citizenship and Immigration Services (USCIS) requires clear evidence that a legitimate relationship exists.

Overview of the K-1 visa application process

The process for a foreign fiancé(e) to obtain a nonimmigrant K-1 visa can be broken down into a few main steps.

• Step 1: The U.S. citizen files Form I-129F on behalf of their fiancé(e).
• Step 2: The fiancé(e) completes Form DS-160.
• Step 3: The fiancé(e) attends a K-1 visa interview and medical exam.

After the visa is approved, the fiancé(e) can enter the U.S. Once they do, the couple has 90 days to marry. After marriage, the foreign spouse can begin the process of getting a Green Card by applying to USCIS for an adjustment of status.

Step 1: The U.S. citizen files Form I-129F

A U.S. citizen must sponsor their fiancé(e) for the K-1 visa—the foreign fiancé(e) cannot sponsor themselves. So the U.S. citizen must start the process by filing the Form I-129F, Petition for Alien Fiancé(e), with USCIS.

Once USCIS approves the K-1 petition, it’s sent to the Department of State’s National Visa Center (NVC), which assigns a case number that it forwards to the U.S. embassy or consulate handling the visa interview.

As of January 2026, the processing time for Form I-129F is about 10 months. NVC processing times typically take four to six weeks.

Documents you need to file Form I-129F

Your exact list depends on your situation, but many K-1 filings include:

• Proof of U.S. citizenship: A passport biographic page, birth certificate, naturalization certificate, etc.
• Evidence you’re both legally free to marry: If there were any previous marriages, divorce decrees, death certificates, etc.
• Proof you met in person in the last two years: Travel records, photos together, itinerary receipts, entry/exit stamps, etc.
• Evidence you have a real relationship: Photos over time, call logs, message screenshots, letters, shared plans, statements of intent to marry, etc.
• Proof you intend to marry within 90 days of arriving in the U.S.: Wedding planning discussions, emails, voicemails, etc.

Step 2: Fiancé(e) completes Form DS-160

After the case reaches the embassy or consulate stage, the foreign fiancé(e) completes Form DS-160, which is the nonimmigrant visa application. Although the form is completed and submitted online, be sure to print the DS-160 confirmation and barcode page to bring to the in-person interview.

Documents you need to file Form DS-160

The requirements can vary by embassy or consulate, but most applicants should be ready with at least :

• A valid passport
• Addresses and travel history details of where you’ve lived and where you’ve traveled in the past few years, particularly if you’ve traveled to the U.S.
• Employment and education history, such as payroll records or transcripts
• Contact info for the U.S. citizen sponsor
• A photo that meets visa photo requirements for the U.S. embassy or consulate where you’re applying

Step 3: K-1 visa interview and medical exam

The consulate handling the application will provide a date and location for an in-person interview. Before the interview, K-1 applicants must also complete a medical examination performed by an authorized panel physician designated by the U.S. embassy or consulate.

If the visa officer determines that more information is needed to make a decision, the case can be sent to administrative processing. This doesn’t mean your case will be denied. It just gives them extra time to look at your records or request additional information before making a final decision. There is no firm timeline for administrative processing.

K-1 visa interview questions

At the interview, a consular officer will generally try to confirm a few key pieces of information:

• You’re eligible for a K-1 visa.
• The relationship you have is genuine.
• You’re not otherwise inadmissible under U.S. immigration rules.

What to bring to the interview

The State Department’s K-1 page lists the typical items applicants are asked to bring:

• DS-160 confirmation page with barcode
• A passport that is valid for at least six months after your stay in the U.S.
• Birth certificate
• Divorce or death certificates for any prior marriages
• Police certificates from your current and prior countries of residence
• Medical examination results, which should be be in a sealed envelope
• Financial support evidence, which may include Form I-134
• Photos and relationship evidence

Note that each U.S. embassy can have extra instructions. Always check the specific guidance for your embassy or consulate.

What happens after K-1 approval

If your K-1 visa is approved, you’ll get your passport back with the visa inside, along with a sealed packet that includes the civil documents you submitted and other paperwork prepared by the U.S. embassy or consulate. Don’t open the packet. It’s meant to stay sealed until you arrive in the U.S., when a DHS officer will open it during your entry process.

Your K-1 visa is typically valid for one entry to the United States, and you must use it within the visa’s validity period, which is up to six months from the date it was issued.

The date you enter the U.S. is the beginning of the 90 days within which you must marry your U.S. citizen sponsor.

After marriage, the K-1 visa holder can live in the U.S. while they apply for permanent resident status (through a marriage Green Card). They can also apply for authorization to work.

Important information about the K-1 visa application

Here are a few important things to know before you begin the K-1 visa application process.

Basic K-1 visa qualifications

• The sponsor must be a U.S. citizen. Green Card holders aren’t eligible to sponsor.
• You must be legally free to marry. Any previous marriages must be legally ended.
• You must have a real relationship, not just a paper relationship. This is often referred to as the “bona fide” relationship requirement.
• You must have met in person within the past two years, with very limited exceptions.
• You must intend to marry within 90 days after entry into the United States.

Income requirements for the K-1 visa

At the interview stage, the consular officer may ask for Form I-134, which is a declaration of financial support. This form requires the U.S. citizen sponsor to confirm that they have the means to support their foreign fiancé(e). 

You typically need the following information from the U.S. citizen:

• Recent tax returns or IRS transcripts
• Recent pay stubs
• Employment letters
• Proof of assets
