For couples separated by a border, the K-1 is often the first official step toward closing the distance. It's also long, paper-heavy and expensive, and small mistakes (an old form edition, the wrong fee) can cost you months. This guide walks through the whole route, from deciding whether the K-1 is right for you to the green card after the wedding.

What is a K-1 fiancé visa?

The K-1 is a nonimmigrant visa for the foreign fiancé(e) of a US citizen. It allows a single entry to the US for the purpose of marrying the petitioner. After the wedding, the foreign spouse applies to "adjust status" to lawful permanent resident (green card holder) without leaving the country.

• Your fiancé(e) enters on the K-1 and must marry you (the petitioner, not anyone else) within 90 days.
• K-1 status can't be extended or changed to another visa type.
• After marrying, they file Form I-485 for a green card.
• Work and international travel generally have to wait for permits from that application.
• Eligible unmarried children under 21 can come on K-2 visas.

Who qualifies for a K-1 visa?

The US citizen petitioner

• Must be a US citizen. Green card holders can't file for a K-1.
• Must be legally free to marry, with any previous marriages ended by divorce, annulment or death.
• Must have met the fiancé(e) in person at least once in the two years before filing. USCIS can waive this in limited cases: extreme hardship, or where meeting would violate strict, long-established cultural or religious customs.
• Must intend to marry within 90 days of the fiancé(e)'s arrival.
• Some criminal convictions (particularly offenses against minors and certain violent crimes) trigger extra disclosure and review. Petitioners who have filed several fiancé petitions before also face additional rules.

The foreign fiancé(e)

• Legally free to marry, with proof that any earlier marriages ended.
• Intends to marry the petitioner within 90 days of entry.
• Admissible to the US: medical, criminal, security and prior immigration history all count.

Same-sex couples qualify on exactly the same terms.

K-1 visa fees in 2026: the full cost table

Government fees for one adult fiancé(e) with no children, as of 2026:

Two things to check before you budget. First, the July 2025 federal budget law created a new "visa integrity fee" on many nonimmigrant visas, and its rollout has been uneven; ask your embassy whether it applies. Second, since 2025, presidential proclamations have suspended or limited visa issuance for nationals of certain countries. If your fiancé(e) is a national of an affected country, check travel.state.gov and speak to an immigration attorney before paying anything.

Other costs to plan for

• Police certificates and certified civil documents (vary by country)
• Certified translations of any documents not in English
• Travel to the embassy city for the medical exam and interview, sometimes with an overnight stay
• The flight to the US
• The wedding, even a simple courthouse one (marriage license fees vary by state and county)
• An immigration attorney, if you use one (fees vary widely; get a flat-fee quote)
• Several months of living costs while your partner waits for a work permit

Our moving budget guide helps you put it all in one place.

The K-1 process, step by step

1. File Form I-129F with USCIS. The US citizen files the petition with the $675 fee, proof of citizenship, proof you're both free to marry, evidence you've met in person in the past two years (photos together, boarding passes, passport stamps, hotel bookings), evidence of a genuine relationship, and signed statements from each of you that you intend to marry within 90 days. Check the I-129F page for the current edition and filing address.
2. Receipt, possible request for evidence, approval. USCIS sends a receipt notice. If something is missing, it sends a Request for Evidence (RFE); answer completely and by the deadline. Approval notices are generally valid for four months, and the consulate can revalidate them.
3. National Visa Center. After approval, USCIS sends the case to the NVC, which creates a case number and forwards it to the US embassy or consulate where your fiancé(e) will interview. This step is usually measured in weeks.
4. Embassy instructions, DS-160 and fees. Your fiancé(e) completes the online DS-160 visa application, pays the $265 K visa fee, gathers documents and books the medical exam with an embassy-approved panel physician.
5. The consular interview. Your fiancé(e) attends alone (you can't usually join). The officer checks the documents and asks about your relationship.
6. Visa issued. If approved, the passport comes back with a K-1 visa, usually valid for a single entry within up to six months. Your fiancé(e) must enter before it expires.
7. Entry and the 90-day clock. The 90 days start on the date of entry shown on the I-94 record.
8. Marry, then file for the green card. File Form I-485 with the I-864 Affidavit of Support, and optionally I-765 (work) and I-131 (travel).

How long does a K-1 visa take?

There's no fixed timeline, and published averages move around. A realistic picture as of 2026:

Check the live numbers on the USCIS processing times tool (select Form I-129F, and later I-485 at your field office) and your embassy's page on travel.state.gov. Track your own case with the receipt number on USCIS case status.

Evidence that makes a strong I-129F

Most delays come from thin or disorganized evidence. Make the officer's job easy:

• Proof of meeting in person: photos of you together (with dates and locations noted), boarding passes, itineraries, hotel or rental bookings, passport stamps.
• Relationship history: a short timeline of how you met, visits, and the engagement.
• Ongoing contact: a representative sample of messages and call logs across the relationship, not hundreds of pages.
• Intent to marry: each of you signs a statement saying you intend to marry within 90 days of arrival. Wedding plans, a venue booking or engagement ring receipts can help.
• Previous marriages: final divorce decrees, annulments or death certificates.
• Translations: full certified English translations of any foreign-language documents.

The K-1 interview: what to expect

Your fiancé(e) typically brings their passport, birth certificate, police certificates from countries they've lived in, sealed or electronically sent medical results, proof previous marriages ended, the DS-160 confirmation, passport photos, relationship evidence, and financial evidence from you (the embassy may ask for Form I-134, Declaration of Financial Support, plus your tax returns and pay stubs). Follow the embassy's own checklist; it overrides general lists.

Questions usually cover:

• How and when you met, and how often you've seen each other
• When and how you got engaged; wedding plans
• Basic facts about the petitioner: job, family, where they live
• Where you'll live and how you'll support yourselves

• Memorizing scripted answers. Officers notice; honest, consistent detail works better.
• Guessing. "I don't remember the exact date" is fine.
• Bringing unrequested piles of paper. Have it organized, but hand over what's asked.

Outcomes: approval, refusal, or administrative processing (Section 221(g)), where the officer needs more documents or checks. 221(g) delays can be frustrating and vary in length.

After arrival: the 90 days and the green card

Getting married in time

Get a marriage license in the state where you'll marry (rules and waiting periods vary by state and county), hold a legal ceremony, and order several certified copies of the marriage certificate. Many couples do a small legal wedding within the 90 days and a bigger celebration later. Our guide to planning a wedding long-distance covers the planning side.

Filing for adjustment of status

• Form I-485 ($1,440 for applicants 14 and older).
• Form I-864, Affidavit of Support, from the US citizen spouse: income generally at least 125% of the federal poverty guidelines for your household size (see I-864P). A joint sponsor can help if your income is short.
• Form I-765 ($260 with a pending I-485) if your spouse wants to work before the green card arrives.
• Form I-131 advance parole ($630 paper / $580 online) if they need to travel abroad while it's pending.
• Medical exam: if you file within one year of the overseas exam, a new full exam generally isn't needed, though a vaccination record supplement may be. After that, you'll need a USCIS civil surgeon.

Don't reuse a form edition you downloaded months ago; check uscis.gov/i-485 on the day you file, since editions and policies (including how public charge is assessed) change.

Conditional green card and removing conditions

Because you'll have been married less than two years when the green card is approved, your spouse will usually receive a two-year conditional green card. In the 90 days before it expires, you file Form I-751 ($750) together, with evidence that the marriage is ongoing: joint lease or mortgage, joint bank accounts, insurance, photos, children's birth certificates. Start saving that evidence from day one.

K-1 vs. spouse visa (CR-1/IR-1): which is better?

If you're willing to marry before your partner moves (for example, in their country or a third country), the spouse visa is the main alternative.

Compare current I-129F and I-130 processing times on the USCIS tool before choosing; the faster route changes over time. The K-1 makes sense if you want to marry in the US with family present and current times favor it. The spouse visa usually wins on cost, work rights and simplicity after arrival. Our spouse visa guide covers that route in detail.

Common reasons for K-1 delays and denials

Surviving the wait as a couple

The K-1 process can take longer than parts of the relationship that came before it, and the uncertainty is its own stress. A few things help:

• Visit if you can. A pending K-1 doesn't automatically stop visits, but your fiancé(e) can be refused a visitor visa or entry if officers think they intend to stay. Carry proof of ties at home and a return ticket.
• Use the time: save money, plan the wedding, research jobs and neighborhoods, and start the closing-the-distance checklist.
• Lean on community. Forums such as VisaJourney have years of timelines from other couples; just remember anecdotes aren't official guidance.
• Protect the relationship from the paperwork. Set a weekly "visa talk" slot so updates don't take over every call. Our guide to coping with uncertainty helps.

Life after the K-1: the first months together

Arrival is the start of another adjustment. Your partner may be unable to work for months, dependent on you for money and transport, far from family and in a new culture, while you plan a wedding and file a green card application. Expect a wobble. Build a financial cushion for at least six months, help them build their own social life, and talk openly about the power imbalance that visa dependence creates.

Next reads: cultural differences after moving abroad, the first 30 days living together, health insurance after a move (arriving from abroad usually opens a special enrollment period), and getting a driver's license.

Frequently asked questions

Can a green card holder sponsor a K-1 fiancé visa?

No. Only US citizens can file Form I-129F for a K-1. A permanent resident who wants to bring a partner has to marry first and then file Form I-130 for the spouse, which usually takes longer than the citizen routes. If you're close to becoming a citizen, it may be worth naturalizing first.

What happens if we don't marry within 90 days?

K-1 status can't be extended, and the fiancé(e) can't switch to another status from inside the US. If you don't marry within 90 days, they're expected to leave, and staying on can create serious immigration problems later. If something goes wrong, such as an illness or a canceled venue, talk to an immigration attorney quickly. A simple courthouse wedding inside the window, with a celebration later, is common.

Can my fiancé(e) work or travel after arriving on a K-1?

Work is technically possible on a K-1-based permit, but it expires with the 90-day status, so most people wait to file Form I-765 together with the green card application after the wedding. For travel, leaving the US while the green card application is pending without advance parole (Form I-131) usually means the application is treated as abandoned. Plan the first months without international trips.

Can my fiancé(e)'s children come on the K-1?

Usually yes. Unmarried children under 21 of the K-1 beneficiary can apply for K-2 visas, as long as they're listed on the I-129F. They travel with the parent or within a year of the K-1 being issued, and file their own green card applications after the wedding, each with its own fee.

Do I need an immigration lawyer for a K-1 visa?

Many couples with straightforward cases file on their own using the official instructions. Consider a lawyer if either of you has a criminal record, a previous visa denial, an overstay or deportation, a previous K-1 or spousal petition, complicated divorces, or if you've only met once and evidence is thin. A one-off consultation to review your packet is a middle option.
