K-1 visa status: how to check your case, the 90-day rule and adjusting to a Green Card

Searching for K-1 visa status means one of two things: tracking your Form I-129F petition online through USCIS and the Department of State, or understanding the legal rules of K-1 nonimmigrant status once you arrive in the United States. When a consular officer issues a K-1 visa, it is valid for up to 6 months for a single entry, and U.S. Customs and Border Protection then admits you in K-1 status for a strict 90-day period to marry your U.S. citizen petitioner, according to USCIS.

How to check your K-1 visa case status from Form I-129F to the embassy

The process of bringing a fiancé(e) to the United States moves across three federal agencies: U.S. Citizenship and Immigration Services (USCIS), the U.S. Department of State (DOS) and U.S. Customs and Border Protection (CBP). Where you check your K-1 case status depends on which stage your petition has reached.

At each stage, background and security checks may be conducted on both the U.S. citizen petitioner and the foreign fiancé(e) using fingerprints, names or other biographic or biometric information.

• Before you mail Form I-129F: To get an email or text message when USCIS accepts your petition at the USCIS Dallas lockbox, complete Form G-1145, E-Notification of Application/Petition Acceptance, and clip it to the first page of your form.
• Stage 1 (USCIS Form I-129F review): Once USCIS accepts your petition, check the status of your Form I-129F online on the USCIS Case Status Online tool and view wait times on the USCIS Check Case Processing Times page. USCIS processes fiancé(e) petitions in the order it receives them.
• Stage 2 (National Visa Center and U.S. Embassy): When USCIS approves Form I-129F, it recognizes the claimed fiancé(e) relationship and sends the approved petition to the DOS National Visa Center (NVC). The NVC issues the foreign fiancé(e) a case number and forwards the petition to the U.S. Embassy or consulate where your fiancé(e) lives. DOS notifies the U.S. citizen petitioner when it is time to apply and when the visa interview is scheduled, and provides K-1 visa application guidance on the Department of State Nonimmigrant Visa for a Fiancé(e) (K-1) page.
• After the interview: The DOS consular officer determines whether your fiancé(e) qualifies for the K-1 visa. If the consular officer does not find the relationship to be bona fide, DOS will not issue the visa and returns the Form I-129F to USCIS. Generally, if DOS returns an expired Form I-129F, USCIS allows it to remain expired, though the petitioner may file a new Form I-129F.

K-1 visa stages, agencies and status actions from USCIS K-1 process guidance (as of May 2026)

K-1 nonimmigrant status vs. the K-1 visa and your Form I-94

Many applicants confuse the expiration date printed on the K-1 visa sticker in their passport with their K-1 nonimmigrant status in the United States. They are two separate clocks controlled by different agencies.

First, an approved Form I-129F petition only means USCIS recognizes an intended marriage. Approval does not give the foreign fiancé(e) permission to travel to the United States and does not guarantee that DOS will issue a visa. Second, the K-1 visa issued by the consular officer only lets you travel to a U.S. port of entry during its validity window to seek admission, and having a K-1 visa does not guarantee admission.

Third, a CBP officer at the port of entry makes the final decision on whether to admit you, after conducting systems queries, collecting biometrics and holding an inspection interview. Once CBP admits you, your K-1 nonimmigrant status begins. If the petitioner needs to withdraw Form I-129F before USCIS approves it, they must submit a signed, written request to USCIS. If USCIS has already approved the petition, the petitioner must contact DOS to withdraw it. Once the fiancé(e) is admitted to the United States in K nonimmigrant status, the petitioner can no longer withdraw Form I-129F.

Because your 90-day marriage clock is governed by your admission record rather than your visa stamp, your first task after landing is checking your Form I-94, Arrival/Departure Record. CBP gathers arrival and departure information automatically from electronic travel records and issues Form I-94 electronically at air, sea and land ports of entry. Your authorized status and expiration date appear in the lower right-hand corner of your Form I-94.

• Retrieve your record online or by app: Use the CBP I-94 website or the CBP Link mobile application and select the Get Most Recent I-94 option to view your I-94 number and Admit Until Date.
• Check the 11-character format: Since May 2019, CBP issues alphanumeric I-94 numbers that are 11 characters long, formatted as 9 digits, a letter in the 10th position and a digit in the 11th position.
• Print a paper copy for your Green Card file: Print a paper version from the CBP I-94 website to verify your immigration status, apply for employment authorization and file Form I-485.

Rules and strict limits of K-1 and K-2 status (the 90-day rule)

Your 90-day admission on a K-1 visa is conditioned on marrying the exact U.S. citizen who filed Form I-129F for you. Your marriage must be valid and bona fide, meaning both you and your fiancé(e) intend to establish a life together and the marriage is not for the sole purpose of obtaining an immigration benefit.

• No extensions allowed: K-1 and K-2 nonimmigrant status automatically expires after 90 days and cannot be extended.
• No change of nonimmigrant status: You cannot apply to change from K nonimmigrant status to another nonimmigrant visa category inside the United States, unless you are applying for T nonimmigrant status (Form I-914) or petitioning for U nonimmigrant status (Form I-918), and you cannot use Form I-539 to request T or U status.
• No adjustment through a different sponsor: A K-1 nonimmigrant cannot adjust status to lawful permanent resident on any basis other than marriage to the U.S. citizen who filed Form I-129F, unless granted U or T nonimmigrant status inside the United States.
• What happens if you do not marry within 90 days: You and any K-2 children must leave the United States at the end of the 90 days. Staying past 90 days without marrying violates U.S. immigration law, which may result in removal (deportation) and affect future eligibility for immigration benefits.
• What if you marry your petitioner after the 90th day: If you marry the U.S. citizen petitioner after the 90-day period expires, your U.S. citizen spouse may file Form I-130, Petition for Alien Relative.
• Rules for K-2 children: Unmarried children under 21 of a K-1 fiancé(e) may come to the United States on a K-2 visa if their names were included on Form I-129F. They must remain under 21 and unmarried to be admitted as K-2 nonimmigrants, and they may travel with the K-1 parent or later, but never before the K-1 parent.

Working and traveling while in K-1 status or pending a Green Card

USCIS provides two paths for work authorization after you arrive in K-1 status, and they have very different validity periods.

Option 1 is applying immediately after admission based on your K-1 status by filing Form I-765, Application for Employment Authorization. Work authorization under this category is valid for only 90 days after your entry into the United States.

Option 2 is applying at the same time you apply for a Green Card after marriage.

Be careful with international travel. The K-1 visa is valid for only a single entry. Once you marry and file Form I-485, if you need to leave the United States temporarily while Form I-485 is pending, look to Form I-131, Application for Travel Documents, Parole Documents, and Arrival/Departure Records. Generally, if you have a pending Form I-485 and leave the United States without an Advance Parole document, you will have abandoned your application.

Adjusting from K-1 status to a Green Card (Form I-485 checklist)

Once you marry your U.S. citizen petitioner within 90 days of K-1 admission, you are treated as an immediate relative of a U.S. citizen, meaning an immigrant visa is always immediately available to you. You file Form I-485, Application to Register Permanent Residence or Adjust Status, while physically present in the United States. USCIS conducts background and fingerprint checks and usually requires both spouses to appear for an interview. Below is our checklist of the documents USCIS lists for a K-1 adjustment package.

• Form I-485, properly completed and signed, with the required filing fee from the USCIS Fee Schedule (Form G-1055).
• Copy of the Form I-797, Approval Notice, for the Form I-129F petition filed on your behalf, and a copy of your marriage certificate.
• Two passport-style photographs, a copy of a government-issued identity document with your photograph, and a copy of your birth certificate.
• Copy of your passport page with the K-1 nonimmigrant visa, your passport page with the admission or parole stamp, and your Form I-94 Arrival/Departure Record.
• Form I-864, Affidavit of Support Under Section 213A of the INA (or Form I-864EZ, if eligible).
• Form I-693, Report of Immigration Medical Examination and Vaccination Record, or a partial Form I-693. If you completed an immigration medical exam before arriving in the United States, you may not need another exam, but you must still show proof that you complied with the vaccination requirements.
• If applicable: certified police and court records of criminal charges, arrests or convictions, Form I-601 or Form I-212 waivers, or documentation of past or present J-1/J-2 foreign residence compliance or waiver (Form I-612).
• For K-2 derivative children (who must apply at the same time as or after the K-1 parent and remain unmarried): their own Form I-485 package, proof of relationship to the K-1 parent (birth certificate or adoption decree), and a copy of the K-1 parent's Form I-485 receipt or approval notice (or Green Card).

Worked example: mapping your 90-day K-1 status timeline

To see how your visa validity and your 90-day status clock interact, walk through this timeline written by our team.

Suppose a U.S. embassy issues your K-1 visa on March 1. Because your visa is valid for up to 6 months for a single entry, you must travel to a U.S. port of entry on or before September 1.

You fly to the United States and CBP inspects and admits you on May 1. That single entry uses your K-1 visa and starts your 90-day K-1 nonimmigrant status period.

Step 1 (Day 1, May 1): You check the CBP I-94 website or CBP Link app, download your electronic Form I-94, and verify that the lower right-hand corner shows K-1 status expiring 90 days later, on July 30.

Step 2 (Day 40, June 10): You and your U.S. citizen petitioner marry in a civil ceremony inside the 90-day window ending July 30, satisfying the K-1 marriage condition.

Step 3 (Day 55, June 25): Instead of filing a standalone K-1 Form I-765 on May 2 that would expire on July 30, you file Form I-485 together with Form I-765 (for a 1-year renewable work permit) and Form I-131 (for Advance Parole) before July 30.

Conditional Green Cards (Form I-751), divorce rules and filing tips

If you have been married for less than two years when USCIS approves Form I-485, you receive conditional permanent resident status under INA 216 and a Green Card valid for 2 years. If permanent residence is granted after your second wedding anniversary, you receive lawful permanent resident status without conditions and a 10-year Green Card.

A 2-year conditional Permanent Resident Card cannot be renewed. You and your U.S. citizen spouse must jointly file Form I-751, Petition to Remove Conditions on Residence, during the 90 days before the 2-year card expires, unless a waiver of the joint filing requirement applies. Otherwise, you lose permanent resident status and become subject to removal.

• Marriage legally terminated after marrying within 90 days: Under the USCIS Policy Manual (Volume 7, Part B, Chapter 7, current as of October 2026), a K-1 nonimmigrant who enters into a valid, bona fide marriage with the Form I-129F petitioner within 90 days remains eligible to adjust status even if the marriage is legally terminated by death, dissolution or divorce before adjustment, regardless of whether the applicant remarries afterward. Conditional residency rules still apply.
• Terminated conditional residence and re-adjustment: If USCIS terminates conditional permanent resident status, an applicant admitted as a K nonimmigrant may seek to adjust status again only based on an approved Form I-130 filed by the same U.S. citizen who filed Form I-129F, and prior conditional time does not count toward naturalization residency.
• Prior Form I-601 waivers: A Form I-601 waiver obtained with a K-1 or K-2 visa application remains valid for Form I-485 without refiling if the K-1 holder married the Form I-129F petitioner.
• Avoiding USCIS lockbox rejections: Mail Form I-129F (edition 01/20/25) to the USCIS Dallas lockbox (P.O. Box 660151 in Dallas, TX for USPS, or the Lewisville, TX suite for FedEx, UPS and DHL) with all pages from the same edition, signed, and with no missing required fields in Part 1 or Part 2 (Classification Sought, Family Name, Date of Birth, and Part 1 Mailing Address). Do not send original civil documents unless requested or non-paper items like thumb drives, CD-ROMs, DVDs or items with chips or batteries.
• Paying USCIS fees: Check Form G-1055 (edition 10/26/26). Pay by mail using Form G-1450 for cards or Form G-1650 for U.S. bank ACH transfers (or Form G-1651 if exempt from electronic payment). Cash is never accepted, and Public Law 119-21 statutory fees cannot be waived.

Practice example

How and when did you and your U.S. citizen fiancé(e) meet in person, and what are your exact plans to marry within 90 days of arriving in the United States?

A strong, honest answer covers two core statutory requirements in two or three clear sentences: your in-person meeting during the two years before Form I-129F was filed, and your concrete plan to marry within 90 days of CBP admission. Start by stating the exact month, year and city where you met in person, and make sure those dates match your Form I-129F petition and passport travel stamps. Next, name the city and state where you will live together after you land and give your specific wedding date or courthouse plan inside the 90-day window. Have your Form I-797 approval notice, copies of your signed intent-to-marry statements, photographs and travel receipts from your trips together, and any venue or civil ceremony booking confirmations organized in your folder so you can hand them over immediately if the consular officer or CBP officer asks.

Both the Department of State consular officer at your visa interview and the CBP officer at the port of entry check that your relationship is bona fide, that you met in person within the two-year window before filing Form I-129F, and that you genuinely intend to marry the petitioner within 90 days of admission.
