K-1 Visa: How U.S. Citizens Can Bring a Fiancé to America
If you are a U.S. citizen engaged to a foreign national, the K-1 visa is the pathway designed for you. It allows your fiancé to enter the United States specifically to get married — and then apply for a green card without leaving the country.
This guide gives you a clear overview of how the K-1 visa works, what the requirements are, and what to expect along the way.
Key Takeaways
- Only U.S. citizens — not green card holders — can petition for a foreign fiancé using the K-1 visa.
- Both partners must have met in person within two years before filing.
- The couple must marry within 90 days of the fiancé entering the U.S.
- After marriage, your spouse must separately apply for a green card through adjustment of status.
- Budget for two stages: the K-1 visa process and the green card application that follows.
- CitizenPath helps you prepare every form correctly at a fraction of attorney costs.
What Is the K-1 Visa?
The K-1 visa — commonly called the fiancé visa — is a nonimmigrant visa issued by the U.S. Department of State. It allows the foreign-citizen fiancé of a U.S. citizen to travel to the United States for the purpose of marriage.
USCIS requires that the couple marry within 90 days of the fiancé's entry into the United States. After the marriage, the foreign spouse can apply for a green card without leaving the country through a process called adjustment of status.
The K-1 visa is only available to U.S. citizens. Therefore, lawful permanent residents (green card holders) cannot petition for a fiancé using this visa category. They must pursue other options, such as a marriage green card after the wedding.
K-1 Visa Requirements
Only the fiancé of a U.S. citizen has a qualifying relationship for the K-1 visa process. The fiancé of a lawful permanent resident does not qualify. Before the couple may begin the process, they must satisfy the following requirements:
- Are legally free to marry;
- Have a genuine relationship;
- Have met each other in person within the two years immediately before filing the petition;
- Intend to marry within 90 days of the fiancé’s admission to the United States; and
- Meet the requirements set in the International Marriage Broker Regulation Act of 2005.
In fact, the visa petition and visa application have separate requirements. For a detailed look at this topic, view our post on the K-1 fiancé visa requirements →
How the K-1 Visa Process Works — Step by Step
The K-1 visa process follows a defined sequence across three government agencies. Each stage has specific requirements, and your case cannot advance until the previous step is complete. Here is what to expect at each stage.
File Form I-129F with USCIS
The U.S. citizen starts the process by filing Form I-129F, Petition for Alien Fiancé, with USCIS. This petition establishes that a genuine qualifying relationship exists between the couple. It must include supporting documents such as proof of U.S. citizenship, evidence of the in-person meeting, and proof that both parties are free to marry.
Each year, USCIS receives hundreds of thousands of I-129F petitions — and rejects or denies a significant portion due to errors and missing documents. Getting this step right matters. Prepare Form I-129F with CitizenPath →
USCIS Reviews and Approves the Petition
Next, USCIS reviews the petition package for completeness and eligibility. If approved, USCIS issues a Form I-797, Notice of Action, confirming the decision. If USCIS needs more information, they may issue a Request for Evidence (RFE), which can add time to the process. A well-prepared petition is the best way to avoid this delay.
Case Transfers to the National Visa Center
After USCIS approves the petition, the case transfers to the National Visa Center (NVC), part of the U.S. Department of State. The NVC routes the case to the appropriate U.S. embassy or consulate — generally the one serving the country where your fiancé lives. This transition typically takes six to eight weeks.
Your Fiancé Applies for the K-1 Visa
The U.S. embassy or consulate contacts your fiancé with instructions to complete the DS-160 K-1 visa application online and schedule a required medical examination with an approved panel physician. Your fiancé will also need to gather supporting documents, including a valid passport, police clearance certificates, and a completed Form I-134, Declaration of Financial Support, from you as the petitioner.
Attend the Consular Interview
A consular officer interviews your fiancé at the U.S. embassy or consulate to verify the relationship is genuine and that your fiancé is admissible to the United States. The officer reviews all original documents and may ask questions about the relationship, your plans to marry, and your fiancé's background. Most applicants who are well-prepared receive a decision the same day. To help your fiancé prepare, review our post on the fiancé visa interview questions →
Your Fiancé Travels to the United States
Once the K-1 visa is issued, your fiancé has six months to use it to enter the United States. The embassy will provide a sealed visa packet to present to Customs and Border Protection (CBP) upon arrival. Use this window to finalize any wedding plans and coordinate travel, especially if children will also be traveling on K-2 visas.
Marry Within 90 Days
Importantly, USCIS requires the couple to marry within 90 days of the fiancé's entry into the United States. This deadline is firm — no extensions are granted. The marriage can be a simple civil ceremony or a formal celebration, depending on your preference and budget. What matters is that it is legally recognized.
Apply for a Green Card
After the wedding, your spouse can apply for a green card without leaving the country through adjustment of status. This package of forms is filed with USCIS and allows your spouse to obtain work authorization and travel permission while the green card is pending. Approval typically takes about one year.

Should You Use a Fiancé Visa or a Spouse Visa?
If you are considering a marriage-based green card, there may be more than one option. And there are trade-offs between immigrating as a spouse and fiancé. Explore your paths to immigrate based on different factors such as cost, marriage status and location.
K-1 Visa Timeline and Processing Time
The timeline for a K-1 visa varies depending on USCIS workloads and the specific U.S. embassy handling the case. In general, couples should expect the process to take several months from start to finish.
USCIS publishes current processing times for Form I-129F on its website. Embassy processing times vary by country. Delays can occur due to missing documents, security checks, or high case volume.
Planning ahead and submitting a complete, accurate petition is the best way to avoid unnecessary delays. For a more detailed look, see the K-1 visa processing time →
K-1 Visa Costs
The K-1 fiancé visa involves several costs throughout the process. At a minimum, you can expect to pay for the USCIS filing fee, the visa application fee, and the required medical exam. Additional expenses may include travel, translations, and vaccinations.
What many couples don't realize is that the K-1 visa is only the first stage. After you marry, your spouse will need to apply for a green card through adjustment of status — and that process carries its own separate set of government fees. Budgeting for both stages upfront helps you avoid surprises later.
Many couples also hire an immigration attorney to prepare their forms — which can add thousands of dollars to the total. CitizenPath gives you the same attorney-reviewed guidance at a fraction of the cost, so you keep more money for the things that matter. Learn more about the K-1 Visa Petition Package →
K-1 Visa vs. Spouse Visa: Which Is Right for You?
Some couples wonder whether to use the K-1 visa or marry abroad first and then sponsor a spouse visa. Both paths have advantages and trade-offs.
The visa comparison comes down to timing, preference, and circumstances. The K-1 visa can be faster in some situations, while the spouse visa may be preferable for couples who are ready to marry before starting the immigration process. See the full fiancé visa vs spouse visa comparison →

What Happens After the K-1 Visa
After the couple marries within the 90-day window, the foreign spouse can apply for lawful permanent residence. The process is called adjustment of status, and it is filed with USCIS.
The foreign spouse will need to file form i-485 along with supporting forms for work authorization and travel. USCIS will schedule an interview, and if approved, the foreign spouse receives a green card. To learn more about the green card application stage, review K-1 Visa to Green Card →
