What is I-539 form used for?

Form I539, known as the “ Application to Extend/Change Nonimmig...nonimmigrant stay or change to a different nonimmigrant status.

The I539 form is commonly used by tourists, students, and dependents of work visa holders. It’s important to submit the I539 while you’re still lawfully present in the U.S.—filing after your visa or status has already expired may have serious legal consequences, including deportation and becoming ineligible to re-enter the United States for up to 10 years. However, there are some special circumstances where failure to file can be excused. For more information on such special circumstances, please reach out for a consultation.

Common Use Cases of Form I539

Some of the most common reasons people file Form I539 include:

• Tourist visa holders (B2 visa) who want to stay longer for personal reasons, such as visiting family or receiving medical treatment.
• Business visitors (B1 visa) who need more time to complete professional activities.
• F1 or M1 visa students who need to reinstate their status after a violation (like missing school).
• Dependents on H4, L2, or L3 visas, who need to extend their stay or change their status in line with the primary visa holder.
• Individuals seeking to change to a different status, such as from B2 to F1 to begin studying.

Who Should File I539

Form I539 should be filed by anyone in the U.S. on a temporary visa who wants to extend their legal stay or switch to another qualifying nonimmigrant status.

You should consider filing Form I539 if:

• You’re in the U.S. on a temporary (nonimmigrant) visa and want to stay longer.
• You are a dependent spouse or child (on an H-4, L-2, F-2 visa, etc.) and need to extend or change your status.
• You are changing to a different visa status, such as: B2 to F1 (tourist to student); F2 to F1 (dependent to primary student); H4 to B2 (dependent to tourist, temporarily)

A timely filed I539 form helps you stay in legal status while you wait for your new classification or extension decision.

Who Shouldn’t File I539

Not everyone is eligible to use Form I539. You should not file this form if:

• You entered the U.S. under the Visa Waiver Program (ESTA)—these entries can’t be extended or changed unless under certain rare exceptions.
• You’re changing to a work-based visa as the primary applicant—those use different forms (like Form I-129).
• You’re seeking asylum or permanent residency (green card).
• You’ve already been ordered removed or deported from the US.

Note: If you are changing from a work visa to a non-work visa, you must use Form I-539. Example: An H-1B worker who is laid off and switches to an F-1 student visa to stay in the U.S. would file Form I-539.

In contrast, Form I-129 is used only for applying for or extending work visas (such as H-1B, L-1, O-1, etc.).
