If you are a U.S. citizen with a partner abroad, there are generally two ways to bring them here: marry first and file a marriage-based green card petition, or file for a K-1 fiancé visa and marry in the United States within 90 days of arrival. Choosing between a K-1 visa vs. a marriage green card mostly comes down to where you want to marry, total cost, and how soon your partner needs to work and travel.

What is the difference between a K-1 visa and a marriage green card?

A K-1 fiancé visa lets the foreign fiancé(e) of a U.S. citizen enter the United States to marry the citizen within 90 days, then apply for a green card from inside the country. A marriage-based green card starts after the wedding, with the citizen (or permanent resident) filing a spousal petition, Form I-130, for the husband or wife.

The K-1 is really a two-stage process: a temporary visa first, then a green card application (called adjustment of status, filed on Form I-485). The spousal route can lead directly to a green card. If your spouse is abroad, that happens through consular processing: an immigrant visa interview at a U.S. embassy, after which your spouse enters as a permanent resident.

Who can use each path?

Only U.S. citizens can file for a K-1 fiancé visa; green card holders cannot. Both U.S. citizens and lawful permanent residents can file an I-130 spousal petition, although spouses of permanent residents usually wait longer because their category is subject to annual limits tracked in the State Department’s Visa Bulletin.

Spouses of U.S. citizens are “immediate relatives,” which means no annual quota applies to them. The couple must also be legally free to marry, and for a K-1, the couple generally must have met in person within the two years before filing (the rule allows limited waivers).

How does the marriage-based green card process work?

The process depends on where your spouse lives when you file. In either case, it begins with Form I-130, which asks USCIS to recognize the marriage as genuine.

If your spouse is abroad (consular processing): after USCIS approves the I-130, the case moves to the State Department’s National Visa Center (NVC), which collects fees, civil documents, and the financial sponsorship form (the Affidavit of Support, Form I-864). Your spouse then attends an interview at a U.S. embassy or consulate. If approved, they enter on an immigrant visa, either CR-1 (conditional resident, if married less than two years) or IR-1 (married two years or more), and the physical green card follows by mail.

If your spouse is already in the U.S. (adjustment of status): a spouse who was lawfully admitted can often file the I-130 and I-485 together, along with optional work and travel permit applications. How your spouse entered, and whether they ever fell out of status, can matter a great deal here, so this is worth reviewing before filing.

How does the K-1 fiancé visa process work?

The K-1 begins with Form I-129F, filed by the U.S. citizen with USCIS. After approval, the case passes through the National Visa Center to the embassy, where your fiancé(e) completes a visa application, medical exam, and interview.

Once admitted on the K-1, your fiancé(e) must marry you (the petitioner, not anyone else) within 90 days. After the wedding, they file Form I-485 to adjust status, usually with a work permit and travel permit application. If the marriage does not happen within 90 days, the K-1 holder generally is expected to leave, and there is no way to switch to a different status in the meantime.

How long does a fiancé visa take compared to a spouse visa?

Both paths often take many months, and in many cases more than a year from filing to arrival, so neither is reliably faster. The K-1 has historically sometimes moved more quickly to arrival, but the K-1 holder then waits again for the green card application to be decided inside the U.S.

Processing times change frequently and vary by service center and embassy. For current figures, check USCIS case processing times and the embassy’s posted wait times. We’d rather point you to live data than quote a number that may be outdated by the time you read this.

A current note: in late August 2026, the State Department paused immigrant visa interviews worldwide while consular officers are trained on new public charge guidance. That pause affects spousal (CR-1/IR-1) interviews; early reports indicated nonimmigrant visas, including K-1, were not covered. The situation is changing quickly, so confirm the status with your embassy before planning around it.

What do the government fees cost?

Government filing fees for the two paths are in a similar range, but the K-1 path usually costs more in total because you pay for both a visa and a later green card application. Current fees below come from the USCIS fee schedule and the State Department’s fee table; they do not include medical exams, translations, travel, or legal fees.

• Spousal route, spouse abroad: I-130 ($675 on paper, $625 online) + immigrant visa application fee ($325) + Affidavit of Support review fee ($120) + USCIS Immigrant Fee after the visa is issued ($235).

• Spousal route, spouse in the U.S.: I-130 ($675/$625) + I-485 ($1,440) + optional work permit, Form I-765 ($260 when filed with a pending I-485) + optional travel permit, Form I-131 ($630).

• K-1 route: I-129F ($675) + K visa application fee ($265) + after the wedding, I-485 ($1,440) + optional I-765 ($260) and I-131 ($630).

The 2025 federal reconciliation law added new immigration fees, mostly in asylum, parole, and temporary protected status cases; they do not change the core family-based fees above. Still, confirm amounts on the USCIS fee schedule just before filing, because a wrong fee can lead to a rejected filing.

Side-by-side comparison

What is conditional residence, and what is Form I-751?

If your marriage is less than two years old when your spouse becomes a permanent resident, they receive a two-year conditional green card instead of a 10-year card. This applies whether they came as a CR-1 immigrant or adjusted status after a K-1.

To keep permanent residence, the couple generally files Form I-751 together during the 90 days before the conditional card expires, with evidence that the marriage is ongoing and genuine. The current fee is $750 on paper ($700 online). Missing the window can cause serious problems, so put the date on your calendar the day the card arrives.

Which path makes more sense for you?

The spousal green card often fits couples who want to marry abroad, want the lower total cost, or want the immigrant spouse to arrive ready to work and travel. The K-1 often fits couples who want to marry in the U.S., with family present, and who accept a second round of paperwork after the wedding.

Conditions at the embassy in your partner’s country, including any current pauses or travel restrictions, can also tip the decision. Both paths involve a public charge review of the household’s finances under a new rule that took effect September 18, 2026.

Frequently asked questions

Can my fiancé(e) come on a tourist visa and marry me instead?

It is legally possible to marry while visiting, but entering on a visitor visa with a preconceived plan to marry and stay can raise serious questions about the visa application. The honest answer depends on the facts and timing, so talk it through with a lawyer before booking travel.

Can a green card holder file for a K-1 visa?

No. The K-1 is only available to U.S. citizens. A permanent resident can marry and file an I-130 for a spouse, though that category is typically subject to longer waits under the Visa Bulletin.

Can a K-1 holder work right away?

Not automatically. A K-1 holder can apply for a work permit on arrival, or more commonly after the wedding together with the I-485. Work begins only once the permit is approved.

Do we need a joint sponsor?

Possibly. The U.S. citizen must sign an Affidavit of Support and generally show household income of at least 125% of the federal poverty guidelines for the household size. If income falls short, assets or a qualifying joint sponsor can often help.
