K-1 Fiancée Visa: Requirements, Process, and Costs

The K-1 fiancé visa lets a U.S. citizen bring a foreign-national partner to the United States to get married within 90 days of arrival. The path starts with a petition filed by the citizen, moves through USCIS review and a consular interview abroad, and ends with the couple marrying and the foreign spouse applying for a green card. From first filing to entry, expect a year or longer and several thousand dollars in fees.

Who Can File and Who Qualifies

Only a U.S. citizen can petition. Green card holders do not qualify to sponsor a fiancé under this category. The law defines a K-1 nonimmigrant as the fiancé or fiancée of a “citizen of the United States” entering to marry that citizen within 90 days of admission.¹

Both people must be legally free to marry. Any prior marriage has to have ended through divorce, annulment, or the former spouse’s death, and the petition needs documents proving it. Both must genuinely intend to marry each other; a relationship built solely for immigration benefits does not qualify.

The In-Person Meeting Rule

Federal law requires the couple to have met face-to-face at least once within the two years before the petition is filed, and the petition will only be approved after the petitioner submits satisfactory evidence of that meeting.² Evidence usually means airline boarding passes, passport stamps, hotel receipts, and dated photographs.

The Secretary of Homeland Security can waive the meeting requirement, but waivers are uncommon. They are generally reserved for situations where meeting in person would cause extreme hardship, or where cultural or religious practices strictly prohibit unsupervised meetings before marriage. Expect to document any waiver request in detail.

Criminal History Is Shared With Your Fiancé

The petitioner’s criminal history is not just reviewed. It is shared with the beneficiary. Federal law requires DHS to give the State Department any criminal background information it has on the petitioner, and that information is then passed along to the visa applicant.³ The disclosed categories include domestic violence, sexual assault, stalking, child abuse, kidnapping, and other violent offenses. Certain prior convictions may bring extra scrutiny or bar filing altogether.

The Petition and Its Supporting Documents

The process opens when the U.S. citizen files Form I-129F, Petition for Alien Fiancé(e), with USCIS.⁴ The form asks for detailed biographical information from both people, including legal names, dates of birth, and employment and address histories.

The petition needs evidence for every eligibility point. At minimum, that means:

Proof of U.S. citizenship: a valid passport or certified birth certificate.
Proof of legal ability to marry: if either party was previously married, final divorce decrees, annulment orders, or death certificates for former spouses.
Evidence of the in-person meeting: airline tickets, passport entry stamps, hotel receipts, dated photos.
Signed statements from both parties confirming they plan to marry within 90 days of the beneficiary’s arrival.⁴

Anything in a foreign language, including birth certificates, divorce decrees, and police clearances, must include a complete English translation. Federal regulations require the translator to certify in writing that the translation is complete and accurate and that they are competent to translate from the original language into English.⁵ The certification should include the translator’s signature, date, and contact information. Professional licensing is not required, but sloppy translations invite delays.

The petition is mailed to the USCIS Dallas lockbox with the current filing fee.⁴ USCIS updates its fees periodically. Check the current amount on the USCIS fee schedule (Form G-1055) or the online fee calculator before filing, because submitting the wrong amount triggers an automatic rejection.

What Happens After USCIS Gets the Petition

After the petition is received, USCIS issues Form I-797C, a Notice of Action, with a receipt number for tracking the case online.⁶ That notice only confirms acceptance of the filing. It is not approval. Officers review the evidence, run background checks, and may issue a Request for Evidence if something is missing or unclear. A prompt, thorough response matters; a weak or late answer can lead to denial.

Processing times swing widely and can stretch past a year. USCIS posts estimated processing times online, and those estimates shift often. Once the petition is approved, USCIS forwards the file to the National Visa Center, which runs additional security screening before sending the case to the appropriate U.S. Embassy or Consulate abroad.

Financial Support: Two Forms, Two Stages

The K-1 process has two separate sponsorship forms, filed at different points. Mixing them up is a common mistake.

Form I-134 Before the Consular Interview

At the consular interview stage, the petitioner submits Form I-134, Declaration of Financial Support, to show they can support the beneficiary during the temporary K-1 period. The consular officer looks at whether household income reaches at least 100 percent of the Federal Poverty Guidelines for the household size. The review is discretionary, and the officer can weigh the petitioner’s overall finances, including savings and property equity. If income falls short, another U.S. citizen or permanent resident who is at least 18 can file a separate I-134 as an additional supporter.

Form I-864 After Marriage

After the couple marries and the foreign national files for a green card, the petitioner files Form I-864, Affidavit of Support. The bar is higher: household income must reach at least 125 percent of the Federal Poverty Guidelines, or 100 percent for active-duty military members sponsoring a spouse or child.⁷ Unlike the I-134, the I-864 is a legally enforceable contract. Both the government and the sponsored immigrant can enforce it. The obligation continues even after a divorce and only ends when the immigrant becomes a U.S. citizen, earns about 40 qualifying quarters of work credit (roughly 10 years), permanently leaves the country, or dies.

If the petitioner’s income does not reach 125 percent, a joint sponsor can file a separate I-864. A joint sponsor must be a U.S. citizen or permanent resident, be at least 18, and live in the United States, but does not need to be related to either party.⁷ Anyone taking on this role is signing a binding financial commitment that outlasts the couple’s relationship.

The Consular Interview and Medical Exam

Once the case reaches the embassy or consulate, the beneficiary completes the DS-160 online nonimmigrant visa application and pays a $265 visa application fee.⁸ Before the interview, the beneficiary completes a medical exam with a physician approved by the embassy. The exam screens for health conditions that would make the applicant inadmissible and records vaccination history on Form DS-3025.⁹ K visa applicants are not required to complete every vaccination before entry, but full vaccination requirements will apply later at the green card stage. Medical exam prices vary by country and provider; plan for a few hundred dollars.

At the interview, the consular officer asks questions to confirm the relationship is real. Expect questions about how you met, your communication history, and your plans after marriage. The beneficiary should bring originals of every document already sent to USCIS, plus updated financial evidence from the petitioner. If the officer is satisfied, the K-1 visa is issued. It is valid for a single entry and must be used within six months.¹⁰

The 90-Day Marriage Deadline

This part is unforgiving. The foreign national must marry the U.S. citizen petitioner, and only that petitioner, within 90 days of admission to the United States. The statute is direct: if the marriage does not happen within three months, the foreign national and any accompanying children “shall be required to depart” and face removal proceedings if they do not.² The 90-day clock starts on the date stamped on the I-94 arrival record, not the visa issuance date.

If things fall apart after arrival, options are narrow. A K-1 holder generally cannot switch to another visa category or apply for a green card through a different sponsor.¹¹ The narrow exceptions cover victims of certain crimes (U visa) or severe trafficking (T visa). For everyone else, the realistic outcome is leaving the country.

Working After You Arrive

K-1 holders are authorized to work in the United States, but not on day one. They need an Employment Authorization Document, obtained by filing Form I-765.¹² Processing takes weeks or months, so most K-1 entrants cannot start work right away. Many couples find it simplest to marry quickly, file for adjustment of status, and include the I-765 in that filing. Plan for a period after arrival with no earned income.

Getting the Green Card

Once the marriage is legally complete, the foreign spouse files Form I-485, Application to Register Permanent Residence or Adjust Status, to move from K-1 nonimmigrant to lawful permanent resident. This is where the I-864 Affidavit of Support comes in, along with another round of biometrics, background checks, and in many cases a second interview.¹¹ The I-485 filing fee is separate from everything paid earlier; check the USCIS fee schedule for the current amount. The marriage certificate is the anchor document at this stage. Without it, the adjustment application cannot go forward.

Because the marriage occurred within two years of the green card being issued, the foreign spouse first receives conditional permanent residence valid for two years. Before that period expires, the couple must jointly file Form I-751, Petition to Remove Conditions on Residence, to convert to a standard 10-year green card. Missing the I-751 deadline can cost the immigrant permanent resident status entirely.

Bringing Children on K-2 Visas

If the foreign fiancé has unmarried children under 21, those children may qualify for K-2 derivative visas. The statute defines a K-2 beneficiary as the “minor child” of the K-1 applicant.¹ Children are listed on the parent’s I-129F petition and go through their own consular processing and medical exams. After the parent marries the U.S. citizen and adjusts status, K-2 children can also apply for adjustment as stepchildren. The marriage between the parent and the U.S. citizen must take place before any K-2 child turns 21, or that child loses eligibility.

What It All Costs

Fees hit at several stages and go to different agencies, and they add up faster than most couples expect. The main line items are the I-129F petition fee to USCIS, the $265 consular application fee to the State Department, the medical exam performed by an approved physician abroad, and the I-485 adjustment of status fee after marriage.⁸ Add document translations, certified copies of records, and travel for interviews, and the total easily reaches several thousand dollars before any legal help. Every fee can change, so confirm current amounts on the USCIS and State Department websites before filing.
