Form I-539 Guide 2026: How to Extend or Change Your Nonimmigrant Status

Form I-539 (Application to Extend/Change Nonimmigrant Status) allows foreign nationals already inside the United States to either extend their current nonimmigrant status or change to a different nonimmigrant category — without leaving the country. This is a critical tool for visitors, students, dependents, and others who need more time in the United States or who need to switch their visa category. This guide covers who can use I-539, how to apply, fees, processing times, and key risks in 2026.

Visa Expiration vs. I-94 vs. Extension of Stay

People often say they want to “extend a visa” while they are already in the United States, but U.S. immigration law separates several different concepts. A visa is the document issued by the U.S. Department of State that allows a traveler to go to a U.S. port of entry and request admission. The visa expiration date does not determine how long the person may remain in the United States after admission.

For most nonimmigrants, the authorized period of stay is controlled by the admission record issued by U.S. Customs and Border Protection, generally reflected on Form I-94 as a specific admitted-until date or, for certain classifications, a notation such as D/S for Duration of Status.

Visa expiration

The visa expiration date generally controls how long the visa can be used to travel to a U.S. port of entry and request admission, subject to the permitted number of entries and the visa classification. A visa can expire while a nonimmigrant is lawfully inside the United States if the person remains within the authorized period of stay and continues to maintain status.

Authorized stay and the I-94

The I-94/admission record is the key record for the period of authorized stay after entry. If it contains a specific admitted-until date, that is generally the date by which the traveler must depart or obtain another lawful basis to remain. The visa expiration date printed in the passport should not be used as a substitute for the I-94 date.

Extension of stay

An extension of stay asks USCIS for additional time in the same eligible nonimmigrant status. Form I-539 is used by many classifications for extension-of-stay requests, while other classifications use different petition procedures. USCIS instructions generally require an extension or change-of-status request to be filed before the current authorized stay expires.

Change of status

A change of status is different from an extension. It asks USCIS to change the person’s nonimmigrant classification while the person is in the United States when the law and category allow it. Form I-539 covers many, but not all, change-of-status situations.

Visa renewal

Visa renewal is a Department of State process for obtaining a new visa document. It is not the same as extending an authorized stay with USCIS. A person who receives an extension of stay inside the United States does not automatically receive a new visa foil in the passport. If a new visa is later required for travel and reentry, the traveler generally follows the applicable Department of State visa application procedures.

Because these terms lead to different agencies, forms, and deadlines, first determine whether the real issue is the visa document, the I-94 authorized stay, an extension of stay, or a change of status before filing anything.

What Is Form I-539 Used For?

Form I-539 serves two distinct purposes:

• Extension of Status: You are currently in the United States in a valid nonimmigrant status that is about to expire, and you want to remain longer in the same category. Example: a B-2 tourist whose authorized stay is ending, who wants to extend their visit.
• Change of Status: You want to switch from one nonimmigrant category to another without leaving the United States. Example: a B-2 tourist who was accepted to a U.S. university and wants to change to F-1 student status before classes begin.

Who Can File Form I-539?

I-539 is used by a wide range of nonimmigrant categories. Common filers include:

• B-1/B-2 visitors seeking to extend their authorized stay
• F-2, J-2, H-4, L-2, O-3, and other dependents extending or changing their dependent status alongside the principal visa holder
• B-2 visitors seeking to change to F-1 student status, M-1 vocational student status, or J-1 exchange visitor status
• J-1 exchange visitors seeking to change to B-2 or another category (subject to two-year home residency requirement if applicable)
• F-1 students who have completed their program and want to change to B-2 status during a grace period

Note: H-1B workers, L-1 workers, O-1 workers, and most other primary employment-based visa holders do NOT use I-539 — their employers file separate petitions (I-129) on their behalf. I-539 is primarily for visitors, students, and dependents.

Key Rules: Filing Before Your Status Expires

You must file Form I-539 before your current authorized stay expires — not before your visa stamp expires (those are different things). Your authorized stay is shown on your I-94 arrival/departure record, accessible at i94.cbp.dhs.gov. If you file a timely I-539 before your I-94 expires:

• You are in a period of authorized stay (“authorized stay pending application”) while USCIS processes your I-539 — you are not accruing unlawful presence during this time
• You can generally continue to remain in the United States lawfully while your I-539 is pending
• If your I-539 is approved, your status is extended or changed as requested
• If your I-539 is denied, you begin accruing unlawful presence from the date of denial

If you fail to file before your I-94 expires, you begin accruing unlawful presence immediately upon expiration — even if you later file I-539. Filing late is not a bar to filing, but the period of unlawful presence before filing counts and can trigger admissibility bars

if you depart the United States.

Form I-539 Filing Fee and Requirements (2026)

• Filing fee: $370 online (myUSCIS) / $420 by paper mail — a $50 online discount, as of 2026
• Biometrics fee: $85 (if required for your category — USCIS will send a biometrics appointment notice)
• Form I-539 — completed and signed
• Copy of your I-94 arrival/departure record (print from i94.cbp.dhs.gov)
• Copy of your current visa stamp (front page of passport + visa page)
• Evidence supporting your extension or change request — for B-2 extensions: explanation of why you need more time, itinerary, evidence of ties abroad; for change to F-1: acceptance letter from SEVIS-certified school, I-20, financial documents showing ability to fund studies
• Filing method: Online through the USCIS online account system (preferred) or by mail — see the official Form I-539 page for current instructions

Form I-539 Update Status

September 2026 rule update: DHS’s fixed-admission rule did not take effect on September 15, 2026. A federal court postponed implementation on September 14, so Duration of Status remains in effect while the litigation continues. USCIS had prepared a revised edition of Form I-539 tied to that rule, but continues accepting the prior edition because the rule’s implementation is postponed. Always verify the current Form I-539 edition directly on the official Form I-539 page before filing.

I-539 Processing Times in 2026

I-539 processing times as of 2026 range from approximately 6 to 18 months depending on the category and filing location (routine B-2 extensions trend toward the faster end; B-2-to-F-1 changes and dependent extensions filed with a principal petition trend slower). This is a significant processing backlog. Important considerations:

• During processing, you are in a period of authorized stay if you filed before your I-94 expired — you are not required to leave while waiting
• If you need to travel outside the United States while your I-539 is pending, your application is automatically abandoned — you cannot re-enter on the pending application. You would need to obtain a new visa abroad and re-enter.
• For change of status to F-1: USCIS must approve the I-539 before the program start date shown on your I-20. If USCIS processing is too slow, you may need to leave the U.S., obtain an F-1 visa abroad, and re-enter as F-1.
• Premium processing is not available for I-539.

Changing from B-2 to F-1 Student Status

One of the most common I-539 uses is changing from B-2 visitor status to F-1 student status. Key requirements and considerations:

• You must have been admitted to a SEVP-certified school and have a valid I-20 issued by that school
• File I-539 well before your program start date — at least 3–4 months in advance given processing times
• If USCIS approves your change of status, you transition to F-1 without leaving the U.S.
• If you entered the U.S. with the intent to study (i.e., you had a school acceptance before entering on B-2), consular officers may view this as misrepresentation — entering on B-2 with the pre-formed intent to study is a problem. Changing from B-2 to F-1 is most straightforward when the intent to study developed after arriving in the U.S.

Frequently Asked Questions: Form I-539

Can I stay in the U.S. while my I-539 is pending?

Yes — if you filed I-539 before your I-94 expired. Once you file a timely I-539, you enter a period of authorized stay while USCIS processes your application. You are not accruing unlawful presence during this time. However, you cannot travel outside the United States while your I-539 is pending without abandoning your application.

How long can I extend my B-2 tourist visa with I-539?

USCIS generally grants B-2 extensions for up to 6 months at a time. The total period of admission as a B-2 visitor generally should not exceed one year. USCIS evaluates extension requests for evidence that you intend to depart after your authorized stay and that you have sufficient financial resources for the extended stay. There is no guarantee of approval — USCIS has discretion to deny extension requests.
