K-1 Fiancé Visa: Requirements, Process & Timeline (2026)
The K-1 visa — the fiancé(e) visa — lets the foreign fiancé of a U.S. citizen travel to the United States to get married. It is a nonimmigrant visa with one defining rule: once your fiancé enters the country, the two of you must marry within 90 days. After the wedding, your spouse applies for a green card from inside the U.S.
This page explains what the K-1 is, who qualifies, the step-by-step process (I-129F → interview abroad → entry → marry within 90 days → adjust status), how it compares to a marriage green card, and where to check current fees and timelines.
Who Qualifies for a K-1 Fiancé Visa
To pursue a K-1, the case generally needs to meet these conditions:
- The petitioner is a U.S. citizen. Lawful permanent residents (green card holders) cannot file a K-1 for a fiancé — they must marry first and petition for a spouse.
- Both partners are legally free to marry. Any prior marriages must be legally ended (divorce, annulment, or death).
- You have met in person within the two years before filing. Narrow exceptions exist (for example, where an in-person meeting would violate long-standing cultural custom or cause extreme hardship).
- You genuinely intend to marry within 90 days of your fiancé's arrival in the U.S.
- The relationship is bona fide — a real relationship, not one entered for immigration benefits.
- The U.S. citizen sponsor can meet the financial requirement to support the incoming fiancé.
The K-1 Process: Step by Step
The K-1 is a two-stage journey: first the fiancé visa (obtained abroad), then the green card (obtained inside the U.S. after marriage). Here is how it flows:
1. File Form I-129F, Petition for Alien Fiancé(e). The U.S. citizen files this petition to have USCIS recognize the fiancé relationship, with supporting evidence of the relationship and proof you have met in person.
2. USCIS review. USCIS adjudicates the petition and may issue a Request for Evidence (RFE) if it needs more documentation.
3. Consular processing abroad. After approval, the case moves through the National Visa Center to the U.S. embassy or consulate in your fiancé's country. Your fiancé completes the DS-160, a medical exam, and gathers required civil documents.
4. The visa interview. Your fiancé attends an interview at the U.S. embassy or consulate. If approved, the K-1 visa is issued.
5. Entry to the U.S. Your fiancé travels to the United States and is admitted on the K-1 visa. The 90-day clock starts on the date of entry.
6. Marry within 90 days. You and your fiancé must legally marry within 90 days of that entry. This deadline cannot be extended, so most couples plan the wedding before their fiancé arrives.
7. Adjust status to a green card. After the marriage, your spouse files Form I-485 (adjustment of status) to become a lawful permanent resident without leaving the country. Employment authorization and a travel document can be requested alongside it.
If your fiancé has unmarried children under 21, they may qualify for K-2 visas to accompany or follow the K-1 parent.
The 90-Day Rule — Why It Matters So Much
The 90-day marriage requirement is the single most important thing to understand about the K-1, and the one that trips couples up:
- The clock runs from the date of entry, not the date the visa was issued.
- It is a hard deadline. There is no routine extension. If you do not marry within 90 days, the K-1 status expires and your fiancé is expected to depart the United States.
- You cannot switch to a different marriage on a K-1. The visa is tied specifically to marrying the U.S. citizen who filed the petition.
- The wedding must be legally valid — an actual, recorded marriage, not merely a ceremony or engagement event.
Because of this, the K-1 rewards planning: many couples set a wedding date early and file the adjustment-of-status paperwork soon after the marriage certificate is issued.
After the Wedding: Adjusting Status
Marriage alone does not make your spouse a permanent resident. The K-1 is only the entry visa; the green card comes from the second stage. After the wedding, your spouse files Form I-485 to adjust status to lawful permanent resident from inside the U.S.
Because you married less than two years before the green card is granted, your spouse will generally receive a conditional (2-year) green card first, and will later need to file to remove those conditions to keep permanent residence. An attorney can confirm how that applies to your timeline.
K-1 Fiancé Visa vs. Marriage Green Card
A significant decision a couple faces is whether to use a K-1 at all, or to marry first and pursue a marriage-based immigrant visa (green card) instead. The core trade-off:
| K-1 Fiancé Visa | Marriage Green Card | |
|---|---|---|
| You marry | After entry — within 90 days | Before the immigration process |
| Petitioner must be | U.S. citizen only | U.S. citizen or green card holder |
| First form | Form I-129F | Form I-130 |
| Status on U.S. entry | Nonimmigrant (not yet a resident) | Becomes a permanent resident on entry |
| Green card obtained | Later, via adjustment (Form I-485) | On or shortly after entry — no second application |
| Where you marry | Must marry in the U.S. | In the U.S. or abroad |
In short, the K-1 often gets your partner into the country sooner but requires a second application for the green card after the wedding; the marriage green card can take longer to first entry but your spouse arrives as a permanent resident ready to work.

Timeline and Cost
Processing times and filing fees are set by the government and change over time, so we do not publish fixed figures here. Instead, check the official tools so you always see current numbers:
- Filing fees: the USCIS fee schedule (Form G-1055) lists current government filing fees for Form I-129F and the later adjustment-of-status forms. These are government fees only — not Altius Law attorney fees.
- Timeline: the USCIS processing times tool shows the current I-129F processing time, which is usually the largest variable in how long a K-1 case takes before the consular stage.
Remember the K-1 is two stages, so the full journey to a green card includes both the fiancé-visa timeline and the later adjustment-of-status timeline.
K-1 Fiancé Visa FAQ
What is a K-1 fiancé visa?
It is a nonimmigrant visa that lets the foreign fiancé of a U.S. citizen enter the United States to get married. The couple must marry within 90 days of the fiancé's entry, after which the foreign spouse can apply for a green card from inside the U.S.
Who can file a K-1 petition?
Only a U.S. citizen can file Form I-129F for a fiancé. Lawful permanent residents are not eligible to sponsor a K-1 and must marry first, then petition for a spouse.
What happens if we don't marry within 90 days?
The 90-day period is a firm deadline with no routine extension. If you do not marry your K-1 sponsor within 90 days of entry, the status expires and your fiancé is expected to leave the United States. This is why most couples set the wedding date in advance.
Does the K-1 give my fiancé a green card?
No. The K-1 is only the entry visa. After the marriage, your spouse must file Form I-485 (adjustment of status) to become a lawful permanent resident. Because the marriage is recent, they typically receive a conditional (2-year) green card first.
Do we have to have met in person?
Generally yes — the couple must have met in person within the two years before filing the I-129F. Narrow exceptions exist, such as where meeting would violate strict long-standing cultural custom or cause extreme hardship.
Should we use a K-1 or marry first and get a marriage green card?
It depends on your priorities — whether getting your partner into the U.S. sooner matters more than having them arrive as a permanent resident, and where you want to marry. See our fiancé and spouse visa page, and talk it through with an attorney.
Can my fiancé's children come too?
Often, yes. Unmarried children under 21 of a K-1 applicant may qualify for K-2 visas to accompany or follow the K-1 parent.
