K-3 visa requirements: eligibility, documents and why most become immigrant visas

To qualify for a K-3 visa, you must be legally married to a U.S. citizen, live abroad, and have a pending Form I-130 filed by your spouse while seeking entry to await USCIS's decision. USCIS charges no fee to file Form I-129F for a K-3 spouse, and the Department of Homeland Security admits K-3 holders for 2 years. Because USCIS usually approves Form I-130 first or simultaneously, most spouses finish through an immigrant visa instead.

Who qualifies for a K-3 spouse visa and a K-4 child visa

The K-3 nonimmigrant visa lets the foreign spouse of a U.S. citizen enter the United States to live and work while waiting for USCIS to decide Form I-130, Petition for Alien Relative. Only U.S. citizens can petition for a K-3 spouse. Lawful permanent residents file Form I-130 under the family Second Preference (2A) category, where visas follow a priority date, and cannot file Form I-129F for a K-3 visa.

Unmarried partners planning to marry in the United States within 90 days of entry use the fiancé(e) path instead, covered in our guide to K-1 visa requirements. Unmarried children under 21 of a K-3 applicant may seek derivative K-4 visas, though Green Card rules for stepchildren are stricter:

• K-3 spouse eligibility: You must be legally married to a U.S. citizen, live outside the United States, have a Form I-130 filed by that spouse, and seek entry to await USCIS's Form I-130 decision.
• K-4 child entry rules: Your child must be unmarried, under 21, and listed on the Form I-129F filed for you. No separate Form I-129F or Form I-130 is needed just to get the K-4 visa.
• Stepchild Green Card age-18 cutoff: To create an eligible step-parent and step-child relationship for a Green Card, the child must have been under 18 when you married the U.S. citizen.
• Separate Form I-130 before age 21: Your U.S. citizen spouse must file a separate Form I-130 for the child before age 21 so the child can apply for a Green Card.

Why most K-3 petitions turn into immigrant visas instead

USCIS states that processing times for Form I-129F are currently comparable to processing times for Form I-130. As a result, USCIS approves Form I-130 before or at the same time as Form I-129F in the vast majority of cases. Once Form I-130 is approved, beneficiaries are no longer eligible for a K-3 or K-4 visa, so the Department of State rarely issues them.

When an approved Form I-130 reaches the Department of State, an immigrant visa is immediately available to a U.S. citizen's spouse, who then applies abroad for admission as a lawful permanent resident. See each stage in our guide to CR-1 visa processing time. Filing Form I-129F is optional, and waiting abroad on Form I-130 alone avoids filing Form I-485 after arrival.

Worked example written by our team (the family is invented): Maya, a U.S. citizen, marries Mateo abroad. Mateo has two unmarried children, Sofia (16 at the wedding) and Lucas (19 at the wedding). Maya files Form I-130 only for Mateo, then files Form I-129F listing Mateo, Sofia, and Lucas. USCIS approves Mateo's Form I-130 on the same day it reviews Form I-129F. First, all three lose K-3 and K-4 eligibility, and Mateo moves to immigrant visa processing. Second, Sofia cannot immigrate with Mateo yet because she lacks an approved Form I-130 at the Department of State, forcing Maya to file a separate Form I-130 for her. Third, Lucas cannot adjust as Maya's stepchild because he was over 18 at the wedding. Filing separate Form I-130 petitions upfront for stepchildren under 18 avoids Sofia's delay.

Step-by-step K-3 filing process and USCIS fees

Many sites mistakenly quote the fiancé(e) fee for K-3 filings. Under USCIS rules and Form G-1055 (edition 10/26/26), there is no fee to file Form I-129F for a K-3 spouse, and Form I-912 is not required for a fee exemption. You still pay the Form I-130 filing fee upfront, plus the Form I-485 fee later if adjusting status in the United States.

Follow the filing sequence and location rules in Form I-130 (edition 04/01/24) and Form I-129F (edition 01/20/25):

• Step 1, File Form I-130 and Form I-130A: Submit Form I-130 online or by mail at the Chicago or Phoenix lockbox (or request embassy filing abroad in limited immediate-relative cases) with Form I-130A and the required fee. Complete only Question 61 or 62 in Part 4, never both.
• Step 2, Keep your Form I-797 receipt notice: USCIS sends Form I-797 (or Form I-797C) confirming receipt. File a separate Form I-130 for each qualifying biological child, stepchild under 18 at marriage, or adopted child, attaching a copy of the spouse's Form I-130 receipt.
• Step 3, Mail Form I-129F to the Dallas Lockbox: Send via USPS to P.O. Box 660151, Dallas, TX 75266-0151, or via FedEx, UPS, and DHL to 2501 South State Highway 121 Business, Suite 400, Lewisville, TX 75067-8003. USCIS international offices cannot adjudicate Form I-129F. Attach Form I-130 filing proof unless filing concurrently, mark N/A on Part 2 Items 53 and 54, and check Part 3 Item 5.d. because IMBRA multiple-filer waivers do not apply to spouses.
• Step 4, Apply in the country of marriage: A spouse who married a U.S. citizen outside the United States must apply for the K-3 visa in the country where the marriage took place. Couples who married in the United States list the spouse's country of current residence abroad (Part 2, Items 47.a. to 47.f.).
• Step 5, Department of State visa application: If USCIS approves Form I-129F before Form I-130, it forwards the petition to the Department of State for a nonimmigrant visa application.

Required documents for Form I-130, Form I-129F and the visa stage

Our team separated the USCIS evidence lists by stage so you do not mix up packets. Mail legible photocopies unless instructions request originals, because USCIS may destroy unrequested originals. Never mail thumb drives, CDs, DVDs, items with batteries or chips, DNA samples, or graphic photos. Include a full English translation for any foreign-language record, signed by a competent translator with their printed name, date, and contact details.

• Packet 1, Form I-130 and Form I-130A: Proof of U.S. citizenship (U.S. birth certificate, unexpired U.S. passport, Certificate of Naturalization or Citizenship, Form FS-240, or an original U.S. consular officer statement), civil marriage certificate, divorce, annulment, or death records ending all prior marriages, legal name change proof, 2 passport photos if applicable, Form I-130A, and bona fide marriage evidence (joint property, joint lease, combined finances, children's birth certificates, or detailed third-party sworn affidavits).
• Packet 2, Form I-129F for a K-3 spouse: U.S. citizenship proof (a U.S. passport or passport card must have at least 5 years validity), civil marriage certificate, termination records for all prior marriages, name change proof, Form I-130 filing proof (Form I-797C, USCIS online printout, or receipt number), and one color 2-by-2-inch passport photo each of petitioner and beneficiary taken within 30 days of filing (white to off-white background, head 1 to 1 3/8 inches, eyes 1 1/8 to 1 3/8 inches, name and A-Number lightly printed on back).
• Criminal and IMB disclosures on Form I-129F: Certified court and police dispositions for specified protection orders, arrests, or convictions under Part 3 (even if sealed or expunged), which DOS discloses to the beneficiary, plus the beneficiary's signed written consent form if you met through an international marriage broker.
• Visa stage vs Form I-485 support and medical forms: K-3 and K-4 visa applicants do not submit Form I-864 at the Department of State, though they must show they will not become a public charge. Later, Form I-864 (or Form I-864EZ) and Form I-693 (when required) must accompany Form I-485 or USCIS may reject it.

What the consular officer checks at a spouse visa interview

Whether interviewing for a K-3 visa or an immigrant visa, the consular officer checks your answers against Form I-130, Form I-130A, Form I-129F, and your civil records:

• Relationship timeline: How and when you met, wedding details, visits, and how you communicate while apart.
• Place of marriage: For K-3 interviews abroad, confirmation that your civil marriage occurred in that country, backed by your marriage certificate.
• Prior marriages and children: Exact dates any prior marriages ended, civil decrees, and each child's birth date and age on your wedding date.
• U.S. spouse's work and finances: Where your spouse lives, their 5-year address and job history from the petition, and how you will avoid becoming a public charge.
• Past U.S. travel and disclosures: Any Form I-94 history, prior petitions, and confirmation that you received any required IMBRA disclosures.

Admission, work permits, travel and extensions on K-3 status

If your spouse enters on a K-3 visa, DHS admits them for a 2-year period. DHS admits a K-4 child for 2 years or until the day before their 21st birthday, whichever is shorter, and status expires at age 21. You can print a paper copy of an electronic Form I-94 from U.S. Customs and Border Protection after arrival.

• Bar on changing nonimmigrant status: K nonimmigrants cannot change to another nonimmigrant category in the United States, except when filing Form I-914 for T status or Form I-918 for U status.
• Automatic work authorization: K-3 and K-4 holders are authorized to work incident to status upon admission. File Form I-765 anytime for an employment authorization card, or apply based on a pending Form I-485.
• Travel without advance parole: You may travel abroad temporarily and seek readmission with an unexpired K-3 or K-4 visa. You need approved advance parole (Form I-131) before leaving only if your K visa will be expired on return and Form I-485 is pending.
• 2-year extensions of stay: File Form I-539 within 120 days before authorized stay expires, showing Form I-130, Form I-485, or an immigrant visa application is pending, or good cause for not yet filing after Form I-130 approval. File a K-4 child's Form I-539 with the K-3 parent's extension.

Green Card adjustment, conditional residence and 30-day termination

To get a Green Card in the United States, a K-3 or K-4 holder files Form I-485 at any time after admission (even while Form I-130 is pending), though Form I-130 must be approved for Green Card approval. Adjustment is restricted to the same U.S. citizen petitioner. If an approved Form I-130 already went to the Department of State, contact the USCIS Contact Center if DOS has not contacted your spouse yet, use the NVC Public Inquiry Form if the case is at the NVC, or contact the U.S. embassy or consulate if CEAC shows the file is at the post.

Petitioners may withdraw Form I-129F by signed written request to USCIS (or DOS after approval), though withdrawal is no longer possible once the spouse is admitted in K status.

• 10-year vs 2-year Green Card: Marriages of at least 2 years at Form I-485 approval receive a 10-year card. Marriages under 2 years receive 2-year conditional residence for the spouse and K-4 children, requiring a joint Form I-751 (not Form I-90) within 90 days before expiration or status terminates.
• CSPA protection for K-4 Green Cards: Although K-4 status strictly ends at age 21, a K-4 child seeking a Green Card may benefit from Child Status Protection Act (CSPA) age-out rules if Form I-130 was timely filed.
• Automatic 30-day K-3 termination: Authorized stay ends 30 days after Form I-130 denial or revocation, Form I-485 denial, immigrant visa denial, or divorce or annulment before permanent residence.
• Extra K-4 termination triggers: A K-4 child's stay also ends 30 days after the K-3 parent's status ends, the child's own petition or application is denied or revoked, turning 21, or marrying before permanent residence.

Practice example

How did you and your spouse meet, when and where did you get married, and have either of you been married before?

Preparation guidance written by our team. Answer all three parts plainly in two or three sentences so your dates match Form I-130, Form I-130A, and Form I-129F. State the month, year, and setting of your first meeting, then give the exact date, city, and country of your civil wedding. For a K-3 interview abroad, confirm the wedding occurred in the country where you are interviewing. Next, state honestly whether either spouse had a prior marriage and the month and year each prior marriage legally ended. Keep your civil marriage certificate and every final divorce, annulment, or death record ready to hand over if asked.

The officer is verifying three requirements at once: a genuine marriage, legal termination of all prior marriages before your wedding, and consular jurisdiction over the place of marriage.
