How to Marry a Foreign Fiancé and Get a Green Card

To marry a foreign fiancé and get a green card, a U.S. citizen chooses one of two immigration paths: a K-1 fiancé visa if the wedding will happen in the United States, or a CR1/IR1 spouse visa if the couple marries abroad first. The K-1 brings your fiancé here on a temporary visa, requires marriage within 90 days of arrival, and then requires a separate green card application. The spouse visa route delivers the green card on entry, but only after you’ve legally married overseas. Both paths run through USCIS petitions, consular interviews, financial sponsorship, and medical exams, and either one typically takes nine months to well over a year from first filing to arrival.

Choosing Between the K-1 and the Spouse Visa

The choice comes down to one question: are you already married, or do you want to hold the wedding in the U.S.?

If you want your partner to enter the country so you can marry here, you need the K-1. It’s a nonimmigrant visa. Your fiancé arrives temporarily, the two of you must marry within 90 days, and then your new spouse files a separate application for permanent residency.¹

If you’re already legally married abroad, skip the K-1. File for a CR1 or IR1 spouse visa instead. Your spouse enters the U.S. as a lawful permanent resident on day one, with no adjustment paperwork required after arrival. That built-in green card is the spouse visa’s biggest practical advantage.

One boundary worth naming: only U.S. citizens can file K-1 petitions. If you hold a green card rather than citizenship, the K-1 isn’t available to you, and marrying abroad and filing an I-130 puts your spouse into the F2A preference category, which typically means a longer wait for a visa number.

The K-1 Fiancé Visa Process

You start by filing Form I-129F, Petition for Alien Fiancé, with USCIS.² Both of you must be legally free to marry, meaning any prior marriages ended by divorce, annulment, or death. You must also have met each other in person at least once within the two years before filing. USCIS can waive that in-person meeting only if the meeting would violate long-established customs of your fiancé’s culture or would cause you extreme hardship.¹

With the petition, submit proof of your U.S. citizenship, documentation that any earlier marriages ended legally, and evidence that your relationship is genuine. Photos together, records of calls and messages, flight itineraries from visits, and receipts from shared trips all help. What USCIS wants to see is a pattern of real contact over time, not a curated highlight reel.

After USCIS approves the I-129F, the case moves to the National Visa Center and then to the U.S. embassy or consulate in your fiancé’s country. Your fiancé completes Form DS-160 (the online nonimmigrant visa application), sits for a medical exam with an embassy-approved physician, and attends a consular interview.³ The medical exam covers screening for certain health conditions and verifies required vaccinations. An applicant missing age-appropriate vaccinations for diseases like measles, hepatitis B, or varicella can be found inadmissible unless the vaccines are administered before the interview or a medical waiver applies.⁴

You’ll also file Form I-134, Declaration of Financial Support, at the consular stage to show you can support your fiancé during the temporary stay.⁵ The heavier I-864 Affidavit of Support comes later, when you file for adjustment of status.

If the consular officer approves the visa, it’s valid for a single entry within six months. The 90-day clock starts the day your fiancé enters the country.

The 90-Day Marriage Window

This deadline does not bend. You must legally marry within 90 days of your fiancé’s admission to the United States. A courthouse ceremony counts the same as a large wedding. What matters is a valid marriage certificate from the state where you marry.

If day 90 passes without a marriage, your fiancé has no legal basis to remain in the country. Staying past that point creates unlawful presence and can trigger removal proceedings, along with a three- or ten-year bar on reentry depending on how long they overstay. Have the marriage license lined up before your fiancé arrives, and check whether your state imposes a waiting period or residency requirement that could eat into your 90 days.

Getting the Green Card After a K-1 Marriage

After the wedding, your spouse files Form I-485, Application to Register Permanent Residence or Adjust Status, with USCIS to apply for a green card.⁶ This is when you sign Form I-864, the Affidavit of Support, a legally binding contract with the federal government committing you to support your spouse so they don’t rely on means-tested public benefits.⁷ The adjustment process includes an interview where USCIS verifies your marriage is genuine.

Your spouse can file Form I-765, Application for Employment Authorization, to obtain a work permit. K-1 holders can apply during the initial 90-day status, and once the I-485 is filed, they can apply under a different category that stays valid while adjustment is pending. Don’t assume your spouse can start working the day after the wedding. An employer needs to see the approved Employment Authorization Document before hiring, and processing can take several months.

Because K-1 marriages are almost always less than two years old when adjustment finishes, your spouse will receive conditional permanent residence, a two-year green card rather than the standard ten-year card. Removing those conditions is a separate step described below.

The Spouse Visa Route If You Married Abroad

If you’ve already married overseas, you file Form I-130, Petition for Alien Relative, instead of the I-129F.⁸ Submit proof of your U.S. citizenship, a certified copy of your marriage certificate, and evidence the marriage is genuine. Stronger evidence goes beyond photos: joint bank accounts, shared lease or property documents, insurance policies naming each other as beneficiaries, and affidavits from people who know you as a couple.

After USCIS approves the I-130, the National Visa Center collects additional documents, including Form DS-260 (the immigrant visa application) and civil records like birth certificates and police clearances.⁹ Your spouse then completes a medical exam and consular interview. You file the I-864 Affidavit of Support at this stage.

Which visa your spouse receives depends on the length of the marriage at issuance. Less than two years, and your spouse gets a CR1 and enters as a conditional permanent resident. Two years or more, and it’s an IR1 with a full ten-year green card.¹⁰ Either way, your spouse walks off the plane a permanent resident. No adjustment of status filing needed.

Removing Conditions on the Two-Year Green Card

If your spouse received conditional permanent residence, whether through K-1 adjustment or a CR1 visa, the green card expires after two years.¹¹ To convert to full permanent residency, you and your spouse jointly file Form I-751, Petition to Remove Conditions on Residence, during the 90-day window immediately before the conditional card expires.¹²

Missing that filing window is one of the most damaging mistakes in the spousal immigration process. If the conditional card expires without a pending I-751, your spouse loses lawful permanent resident status. Set a calendar reminder well in advance. The I-751 requires fresh evidence the marriage is still genuine: updated joint financial records, a shared lease or mortgage, insurance documents, and similar proof of a life built together.

If you’ve divorced or your spouse experienced domestic abuse during the marriage, your spouse can file the I-751 with a waiver of the joint filing requirement. The grounds are narrow, but the waiver exists so an abusive petitioner can’t hold immigration status hostage.

Financial Sponsorship Requirements

Both paths require financial sponsorship, but the form depends on the stage. Form I-134 covers the K-1 consular interview. Form I-864 covers the I-485 adjustment after a K-1 marriage and the CR1/IR1 consular processing.⁷

The I-864 is the heavier obligation. It’s a legally enforceable contract. If your sponsored spouse receives means-tested public benefits, the agency that paid can sue you for repayment. The obligation ends only when your spouse becomes a U.S. citizen, earns 40 qualifying quarters of work under Social Security, permanently leaves the country, or dies. Divorce alone does not end it, which surprises many petitioners.

To qualify, you generally need household income at or above 125% of the federal poverty guidelines for your household size, which includes you, your spouse, any dependents, and anyone else you’ve previously sponsored. For a household of two in the contiguous United States, that threshold for 2026 is approximately $27,050 per year. If your income falls short, you can bring in a joint sponsor, a U.S. citizen or permanent resident who signs their own I-864 taking on the same legal obligation. Certain assets can also help bridge a gap.

If Your Fiancé or Spouse Has Children

Unmarried children under 21 can come along. On the K-1 path, they enter on K-2 derivative visas listed on the I-129F, complete their own DS-160 forms, medical exams, and interviews, and later file for adjustment of status alongside your new spouse.

On the spouse visa path, minor children are added as derivative beneficiaries on the I-130 and go through NVC processing with your spouse, entering on derivative immigrant visas. Either way, budget for additional filing fees, medical exams, and vaccination requirements per child.

Costs and Processing Times

USCIS adjusts its filing fees periodically, so verify current amounts against the USCIS fee schedule (Form G-1055) before you file. The forms you’ll see charges for depend on your path:

K-1 path: I-129F, DS-160 visa application fee, I-485 adjustment filing (typically including biometrics), I-765 work permit, and I-864 processing.
Spouse visa path: I-130, DS-260 visa application fee, immigrant visa issuance fee, and I-864 processing.
Both paths: medical examination (typically $250 to $650, varying by location and vaccinations needed), certified translations of foreign documents (roughly $25 to $35 per page), and a marriage license fee that varies by state and county.

Government filing fees alone commonly run $2,000 to $3,000 or more before you add medical exams, translations, and travel.

Timelines are harder to pin down. The K-1 process currently runs roughly 9 to 11 months from filing the I-129F through visa issuance, though it swings with USCIS service center workload and embassy appointment availability. The CR1/IR1 route often takes a similar span or longer depending on NVC backlogs. USCIS publishes updated processing times on its website, and you can check your service center’s estimate once you’ve filed.

Mistakes That Derail These Cases

A handful of patterns account for most of the avoidable trouble:

Thin relationship evidence. A few photos and some text messages won’t carry a petition. Officers see fraudulent filings regularly, and sparse proof makes legitimate couples look suspect. Build a file that documents the relationship over time.
Missing the 90-day K-1 marriage deadline. Sort out the marriage license requirements before your fiancé lands. State waiting periods can quietly consume your window.
Forgetting the I-751 filing window. The 90 days before the conditional green card expires is easy to overlook, and missing it puts your spouse’s status at risk.
Income shortfalls on the I-864. Line up a joint sponsor early if your income might not clear the threshold. Scrambling for one at the last minute causes delays.
Untranslated or uncertified documents. Every foreign-language document submitted to USCIS needs a certified English translation. Skipping that produces a request for evidence at best and a denial at worst.
