Form I-539 is the request that USCIS uses for certain nonimmigrants to extend their stay or change to another visa category. The underlying rule is found in 8 CFR 214.1(c): anyone who wants to remain beyond the authorized period must request the extension in the form and manner prescribed by USCIS. This guide describes, step by step, what the form and the rule require, so you can organize your paperwork with confidence.
What Is Form I-539?
According to the official I-539 page, the form is used by certain nonimmigrants who want to extend their stay or change to another nonimmigrant status. The same page lists other uses: residents of the Commonwealth of the Northern Mariana Islands (CNMI) requesting initial status, F and M visa holders requesting reinstatement, and people requesting V status or an extension of it.
In practice, the I-539 comes up most often for people who entered as visitors (B-1/B-2) and need more time, and for dependents of someone holding a work visa. For the worker themselves, the path is usually different, as we'll see below.
Who Uses the I-539 and Who Uses the I-129?
8 CFR 214.1(c)(1) states that, for workers in categories such as H-1B, L-1, and O-1, the request for extension or change of stay is made on Form I-129, generally by the employer or petitioner. Dependents generally use the I-539, although the rule allows them to be included in the worker's petition when the form provides for it.
8 CFR 214.1(c)(2), on the other hand, covers other nonimmigrants: anyone who wants to remain beyond the authorized period must request the extension on the form prescribed by USCIS. If family members are included in the same request, they receive the same extension period, and the shortest period granted to any member applies to all.
Which Categories Cannot Request an Extension?
8 CFR 214.1(c)(3) lists classes that cannot extend their stay. These include people admitted as B-1/B-2 under the Visa Waiver Pilot Program, the C, D, and K-1/K-2 categories, and those admitted for "duration of status," except for the exception under paragraph (m). For this reason, the first step is to check, on your I-94 and against the rule, which category your entry was recorded under. It is USCIS, not this guide, that decides whether a case qualifies.
What Is the Deadline to File?
The rule in 8 CFR 214.1(c)(4) is clear about timing: an extension or change cannot be approved for someone who failed to maintain status or whose status expired before filing. USCIS may, at its discretion, excuse a delay caused by extraordinary circumstances beyond the applicant's control, among other conditions. When that happens, the extension is counted from the date the previous stay ended.
For this reason, timing matters: the request should be prepared and sent while the current period is still valid. For those already planning ahead, it's also worth reviewing how the USCIS biometrics notice and the ASC appointment work, since USCIS may request biometrics after filing.
What Evidence Does USCIS Request?
8 CFR 214.1(c)(6) states that the applicant must present evidence that they maintained their previous status. The rule cites, as examples, documents such as pay stubs, W-2s, income tax returns, or contracts, depending on the type of status.
In addition, 8 CFR 214.1(c)(7) notes that even when eligibility appears to be met, USCIS may grant the extension at its discretion. In other words, a well-documented request organizes the information, but the decision rests with the agency.
What Are the Steps of the Request?
- Confirm the category recorded on your I-94 and whether it is among those eligible to request an extension, according to 8 CFR 214.1(c).
- Check the form's page on USCIS and use the current edition of the form and instructions, since USCIS states it does not accept previous editions.
- Fill out the form completely. The USCIS page highlights that USCIS rejects any I-539 without a signature, at Part 5, item 3.a.
- Gather the evidence of maintained status described in 8 CFR 214.1(c)(6).
- Check the fee in the current official USCIS fee schedule before filing. The form's page refers to special instructions for the amount, so this text does not repeat numbers that may change.
- If filing by paper, the I-539 page indicates the mailing address (Direct Filing Addresses) and the use of the Lockbox. To receive notification by email, attach Form G-1145 to the first page.
- Keep your receipt and follow USCIS notices, including a biometrics appointment and a possible RFE, the request for additional evidence.
What Recent Edition and Fee Changes Should I Check?
USCIS frequently updates form editions and fee amounts. In 2026, USCIS announced a new edition of both the I-539 and the I-765, the 09/15/26 edition, according to the official USCIS notice. Before any filing, always check the form's page and the fee schedule on the USCIS website, which are the current source.
What If I'm a Visitor or Student?
Anyone who entered as a visitor can find context about the visa on the page about the B1/B2 visa: requirements, fee, and steps. Students can see the guide on the F-1 visa, I-20, and student steps. 8 CFR 214.1(c)(8) addresses a specific situation for F, I, and J students with a pending request who leave the country, and this is the kind of point you check against the rule, not from memory.
