Almost every nonimmigrant who enters the United States discovers, sooner or later, that the expiration date stamped on their passport visa and the expiration date on their I-94 do not match. The visa only authorizes the request to enter the country; it is the I-94, issued electronically by U.S. Customs and Border Protection (CBP) at each admission, that determines how long the foreign national may legally remain on U.S. soil. Confusing the two dates is one of the fastest ways to fall into unlawful presence — a situation that can trigger three- or ten-year bars of inadmissibility.
The good news is that, for most nonimmigrant categories, it is possible to request an I-94 extension without leaving the United States. This guide details who may apply, which forms to use, how much it costs in 2026, and how long the process typically takes at USCIS.
What Is the I-94
The I-94 is the electronic arrival/departure record used by the U.S. government to verify the legal status of each nonimmigrant visitor. Since 2013, the paper form has no longer been issued at airports, seaports, and major land crossings; the process became electronic, based on airline manifests and inspection by the border officer. The document shows the visa category admitted, the date of entry, and the date by which the foreign national must depart.
The authorized period varies on a case-by-case basis. Tourists with B-1/B-2 visas, for example, typically receive up to six months per entry, but the officer may shorten that period if deemed appropriate. F-1 and M-1 students, J-1 exchange visitors, and A and G diplomats frequently receive the notation D/S (duration of status), which ties the stay to the length of the program. The record can be checked at any time at i94.cbp.dhs.gov.
Who Can Apply for an Extension
To request an I-94 extension, the foreign national must cumulatively meet several requirements: have been lawfully admitted to the United States with a valid nonimmigrant visa, maintain status throughout the entire stay, hold a passport valid for the intended period, not have committed any acts that render them inadmissible, and not have violated the terms of admission.
Some categories, however, are ineligible for extension within the U.S.: visa C (transit), D (crewmember), K-1 and K-2 (fiancé(e) of a U.S. citizen and dependents), S (witnesses and informants), TWOV (transit without visa), and WT/WB (entry under the Visa Waiver Program, including travelers with ESTA). For those in these categories, any stay beyond the initially granted period requires departure from the country.
Forms: I-539 and I-129
The choice of form depends on the visa type. Non-employment-based categories use Form I-539, Application to Extend/Change Nonimmigrant Status. Employment-based categories use Form I-129, Petition for a Nonimmigrant Worker, which is filed by the employer, not the worker.
Form I-539
The I-539 is used by holders of A-3, B-1/B-2, G-5, H-4, K-3, K-4, L-2, M, N, NATO-7, O-3, P-4, R-2, any V, and TD visas. The form can be submitted online through the MyUSCIS portal or on paper. The online version has a lower cost per application but requires separate payment for each co-applicant. The paper version charges a single fee that covers the applicant and their dependents, which is why families generally prefer paper filing.
Each co-applicant included in a paper I-539 must attach a separate I-539A. The questions cover personal information, most recent I-94 number, passport information, date of last U.S. entry, current visa category and its expiration, number of persons included in the request, new intended departure date, foreign address, immigration petition history, and criminal history.
Part 4 of the form, dedicated to Additional Information About The Applicant, includes questions about status violations, criminal convictions, and other grounds of inadmissibility. Any doubt about this section warrants consultation with a licensed attorney: answering incorrectly or omitting information can compromise not only the current petition but the entire future immigration history.
Form I-129
Holders of work visas — E-1, E-2, E-3, H-1B, H-1B1, H-2A, H-2B, H-3, L-1A, L-1B, O-1, O-2, P-1, P-2, P-3, P-1A, P-2S, P-3S, Q-1, R-1, TN-1, and TN-2 — depend on their employer to file the I-129. The worker’s dependents (spouse and unmarried children under 21), in turn, must file their own I-539, ideally together with the worker’s I-129 petition.
Visa and I-94: Why the Dates Differ
The visa stamped in the passport is simply the key that allows the foreign national to request admission at the border. The duration of stay, however, is decided by the CBP officer at the time of entry. That officer may limit the I-94 based on several factors: remaining passport validity, the applicant’s recent travel pattern, the declared purpose of the visit, or simple discretionary authority provided by regulation.
A recurring example: foreign nationals whose passport expires before the visa’s validity end date receive an I-94 limited to the passport’s expiration. To remain in the U.S. longer, the passport must be renewed and a border run made, or an extension must be requested. Another common case involves B-2 holders with a ten-year visa: the standard I-94 lasts six months, but if the officer notices a pattern of lengthy successive stays, they may grant only one month.
Required Documents
The documents required vary by visa category. The basic set includes a copy of the current I-94, the approval notice for the current visa, a copy of the relevant passport pages, and proof of U.S. address. The complete list by category is found in the official instructions for I-539 and I-129, published by USCIS.
It is highly recommended to attach a declaration letter detailing the reason for the request, the temporary nature of the stay, departure plans after the extension, and how the applicant will support themselves financially during the additional period. Applications with a robust declaration tend to proceed with fewer requests for evidence (RFEs).
Sample Extension Letter
A practical example of a declaration for a B-2 extension due to a family emergency:
Applicant’s Declaration — Anna Katerina Ivanova. I, Anna Katerina Ivanova, born on September 8, 1992, in Sofia, Bulgaria, and currently residing at 1550 N. Lake Shore Drive, Apt. 12C, Chicago, IL 60610, submit this declaration in support of Form I-539 to request an extension of my B-2 status.
I entered the United States on a B-2 visa to visit my sister, a U.S. citizen. My authorized stay ends on November 30, 2025. My sister underwent an unexpected surgical procedure and will require significant home care during her recovery. I am requesting an extension of three additional months to support her while her husband returns to work.
I fully understand the temporary nature of B-2 status. I maintain a permanent residence and full-time employment in Sofia, Bulgaria, at ul. Tsar Ivan Asen II 28, fl. 4, 1124. I intend to return to my home country as soon as my sister has recovered.
Fees in 2026
The current fees, per the USCIS final rule published in January 2024 and still in effect in 2026, are:
- Paper I-539: $470, covering the applicant and dependents included in the same petition
- Online I-539: $420, with separate charges per co-applicant
- I-129: $1,015 base fee, paid by the employer, plus an Asylum Program Fee of $600 ($300 for small employers with up to 25 employees, waived for nonprofits and qualifying educational institutions)
- Optional Premium Processing: $2,805 for guaranteed review within 15 business days
- Land border I-94 (for land port of entry): $30, adjusted effective September 30, 2025
Processing Times
Review time depends on the service center and visa category. At egov.uscis.gov/processing-times, you can check the current average by form and center. I-539 cases can range from a few months to over a year during high-volume periods; I-129 without Premium Processing typically takes four to eight months, depending on the visa type.
If the I-94 expires before USCIS decides on a petition filed within the deadline, the foreign national remains in authorized stay and does not accrue unlawful presence — but loses work authorization (in the case of employees with an I-129) until the extension is approved. Monitor the case status through MyUSCIS and respond immediately to any RFE.
When the I-94Cannot Be Extended
There are situations where an extension is not viable: the applicant is already out of status, has committed serious violations, has been convicted of crimes affecting admissibility, or belongs to one of the ineligible categories. In these cases, departing the U.S. before the I-94 expires and seeking a new admission at the border is generally the safest alternative. Remaining beyond the authorized period, even for a few days, can result in automatic visa cancellation and a three- or ten-year reentry bar, depending on the duration of the unlawful presence.
Typical Cases
Among the most common situations that motivate an extension are parents with B-2 visas who need to stay longer to support sick children, pregnant women who faced medical complications, travelers who missed flights due to family health issues, and H-1B professionals who lose their jobs and transition to B-2 status while arranging their departure. Laid-off H-1B workers, it is worth noting, have a 60-day grace period under 8 CFR 214.1(l) to find a new employer, transfer status, or leave the United States.
