K-1 Visa: A Comprehensive Guide to the Fiance Visa

There are multiple ways to bring a spouse or family member to the United States on a Green Card, but they don’t apply to engaged couples who aren’t yet married. If you are a U.S. citizen with a fiancé(e) who is living in another country, you may be able to reunite and marry in the U.S. using a K-1 visa. Also known as a fiancé(e) visa, the K-1 requires you to file a petition to U.S. Citizenship and Immigration Services (USCIS), along with evidence that you’ve actually spent time with your foreign fiancé(e) and have plans for a life together.

What is a K-1 visa?

The K-1 is a nonimmigrant visa for foreign fiancé(e)s of U.S. citizens. It allows the foreign partner to enter the country specifically to get married. Once the fiancé(e) enters the U.S., they must get married within 90 days. After the marriage, the foreign spouse can stay in the country and apply for a Green Card through adjustment of status.

If you’re already married, you’ll need to apply for a different visa, like the IR-1, to bring your spouse to the United States.

Who qualifies for a K-1 visa

Both partners must meet certain requirements to qualify for the K-1 visa, though the responsibility largely falls on the U.S. citizen who is sponsoring a fiancé(e) from overseas.

• The sponsoring spouse must be a U.S. citizen.
• The sponsor must meet income requirements to support their fiancé(e).
• The sponsor must intend to marry the fiancé(e) within 90 days of their arrival in the U.S.
• The foreign fiancé(e), as the visa applicant, must have a clean legal record and a bill of health.
• Both partners must be legally free to marry. Any prior marriages should be properly terminated, with the necessary documents to prove it.
• The relationship must be genuine, and not just for immigration purposes.
• The couple must have met in person within the last two years.

Proving a real relationship for a K-1 visa

As with other marriage-based visas, a successful K-1 petition requires proving to USCIS that your engagement is genuine and not just an attempt to get immigration benefits for the foreign spouse.

In particular, you and your fiancé(e) will need to show that you met at least once within the two years before you file a petition. You should be prepared to provide USCIS with supporting documents or other evidence that clearly demonstrates you’ve actually spent time together and have plans for a life together.

It is possible to get a waiver for the in-person meeting requirement, such as if your religion forbids you from meeting before marriage, but waivers only apply in a small number of cases.

K-1 visa documents to prove a real relationship

Strong K-1 visa applications include a mix of documents that, when taken together, show you’ve had consistent, meaningful contact over time. Potential documents include:

• Photos of you as a couple, including on trips over time
• Communication records, such as phone logs, text message history, emails, or social media chats
• Evidence of shared past and future plans, like travel itineraries
• Evidence of shared finances, like shared bills, bank accounts, or rental or property agreements
• Statements and letters of support from family and close friends

Common mistakes K-1 fiancé(e) should avoid

• Submitting weak relationship evidence: A handful of photos together is rarely enough. Immigration officers expect to see an ongoing, serious relationship.
• Inconsistencies across forms and interviews: Even small discrepancies in dates or details can raise concerns.
• Misunderstanding financial requirements: Failing to properly document the U.S. citizen’s income—or assuming their income is sufficient—can delay approval. You usually need at least 100% of the Federal Poverty Guidelines for your state and family size, but you can find the latest requirements in the Form I-134 instructions.
• Not meeting the in-person meeting requirement: This is a strict rule and formal waivers only apply in narrow circumstances.
• Planning a wedding too early or filing too late: This may not affect the ultimate approval of your K-1 visa, but it can create unnecessary stress and logistical issues.
• Missing documents or avoidable errors: Even when this doesn’t lead to a visa denial, if USCIS needs to send you a formal request for evidence, it can increase processing times by weeks.

K-1 visa application process

Here are the steps you can take to apply for a K-1 fiancé(e) visa. Learn more in our full guide to the K-1 visa application process.

1. The U.S. citizen files Form I-29F. The sponsoring spouse (the U.S. citizen) can begin the K-1 application process by filing Form I-129F, Petition for Alien Fiance and paying the $675 filing fee with USCIS.
2. Wait for approval. USCIS will review the I-129F petition and issue requests for additional evidence if needed. Respond quickly and completely to avoid delays. After the petition is approved, the bulk of the process is completed by the foreign fiancé(e) at their local U.S. embassy or consulate.
3. Submit Form DS-160. The foreign fiancé(e) must complete the online visa application, Form DS-160, pay the $265 fee, and submit all the necessary supporting documents.
4. Attend a visa interview. The fiancé(e) will receive an appointment date to attend a K-1 visa interview and a medical exam. The consular officer will typically let them know if they’ve been approved at the interview, but each consulate operates a little differently. Some cases may require additional background checks or document verification through administrative processing.
5. Travel to the U.S. After K-1 visa approval, the fiancé(e) will receive a visa stamp and will have up to six months to enter the U.S. You only have 90 days to get married after entering the country, so you may also want to use the six months to plan the wedding or marriage ceremonies.
6. Get married within 90 days. The K-1 visa requires you to get married within 90 days of entering the U.S. This deadline cannot be extended. Staying in the U.S. more than 90 days without getting married may make the foreign fiancé(e) subject to deportation or restrictions on becoming a permanent resident. That said, you can often still get a Green Card if you overstay your visa and get married.

K-1 visa processing time

In total, you should expect the K-1 visa processing time to take at least a full year from filing the initial I-129F petition to visa issuance.

Current USCIS processing times for most Form I-129F petitions is up to 11.5 months. After that, DS-160 processing and the wait time to schedule an interview may take anywhere from a couple of weeks to months, depending on the embassy.

K-1 visa approval rates

In recent years, approval rates for K-1 visas have been over 85%. That doesn’t mean getting a K-1 is easy, though. Failing to include clear and comprehensive evidence of your relationship will lead to a visa denial. One of the best ways to ensure your application has everything it needs is to work with an experienced K-1 visa lawyer.

What happens after your visa approval and marriage?

A key benefit of the K-1 visa is that it automatically leads to a Green Card. As long as you get married within 90 days of entering the U.S. on a K-1, you can apply for a Green Card using Form I-485 for adjustment of status. You can also apply for work authorization (using Form I-765) and international travel permission at this time.

If you failed to marry within 90 days, you will go through a longer process of submitting Form I-130 and then the I-485.

Conditional Green Cards

One thing to keep in mind is that there are two types of Green Cards: two-year conditional Green Cards and standard 10-year Green Cards. What you get is based on the length of your marriage. If the marriage is less than two years old at the time of Green Card approval, which is generally the case for K-1 visa recipients, the foreign spouse will receive a conditional Green Card. Conditional Green Cards last two years and offer all the same benefits, but they expire after two years. 

Renewal requires you to apply to remove conditions and reaffirm to USCIS that your marriage was legitimate. Then you will receive a standard 10-year Green Card. (The expiration date of your Green Card has no effect on your status as a lawful permanent resident.)

Planning for a K-1 fiancé(e) visa

Applying for a K-1 visa takes time and effort. Decisions you make early—how you present your relationship, how you document income, when you file—can affect not just approval, but how long the process takes. If you’re worried about proving a genuine relationship, aren’t sure which documents you need, or have any other questions during the K-1 and Green Card process, know that Manifest works with couples at every stage, from starting the initial petition to removing conditions from a conditional Green Card.

FAQs about K-1 visas

How much does a K-1 visa cost?

Expect the total cost to get a K-1 visa to be over $1,000. That includes a $675 filing fee for Form I-12F, $265 to file Form DS-160, and a medical examination that can cost $200 or more in some locations. There may be additional fees for document translations, interpretation services, travel expenses, and K-1 attorney fees. Applying for a Green Card after marriage will cost at least another $1,400.

What are the K-1 visa income requirements?

The U.S. citizen sponsor must typically meet at least 100% of the Federal Poverty Guidelines for their state and household size to qualify for a K-1 visa. After marriage, higher requirements (125%) apply during the Green Card process.

Do you have to follow the two-year meeting rule?

You must show that you and your fiancé(e) met in person at least once within the two years before filing your K-1 visa petition, unless you qualify for a limited waiver based on hardship or cultural reasons.

What happens if you don’t marry within 90 days?

If you don’t get married within 90 days, the K-1 visa expires and the foreign fiancé(e) must leave the United States. There is no extension or conversion to another status without marriage. You may still be able to get a Green Card after overstaying and getting married, but eligibility depends on your situation.

Can my fiancé’s children get a K-1 visa?

Unmarried children under 21 may accompany the foreign fiancé(e) on a K-2 visa, as long as they are listed on the Form I-129F. They can travel with the fiancé(e) or follow later, but they cannot enter the U.S. before the K-1 visa holder.
