If your authorized stay in the United States is running out and you are not ready to leave, Form I-539 is often how you ask to stay longer or switch to a different status. Officially titled the Application to Extend/Change Nonimmigrant Status, it is the form a visitor, student, or dependent uses to tell USCIS, “I need more time,” or “I need to change what I am doing here.” Filed correctly and on time, it can protect your lawful presence. Filed late or incompletely, it is one of the easier applications to lose.
We help people in Central Florida file these requests and fix the ones that went sideways. This plain-English guide covers who files, what it costs in 2026, the deadline that matters most, and the mistakes we see most often. If you are close to your deadline, do not wait to call us at (407) 917-2087.
What is Form I-539?
Form I-539 is the application most nonimmigrants use to either extend their current status or change to a different nonimmigrant category while staying in the United States. According to USCIS, it covers people such as B-1 and B-2 visitors, F and M students, and dependents in several categories who need to extend or change their status without leaving the country.
The form does two distinct jobs. An extension asks to keep the same status longer, for example a tourist who needs additional time. A change of status asks to move from one category to another, for example a visitor who has been admitted to a school and wants to become a student. Knowing which one you are requesting shapes the entire application.
Who should file Form I-539?
You generally file Form I-539 if you are a nonimmigrant inside the United States who wants to extend or change status without traveling abroad. Common filers include B-1/B-2 visitors seeking more time, F-1 and M-1 students, and the dependent spouses and children of various visa holders who need their own status extended or changed.
Not everyone uses this form. Workers in categories like H-1B and L-1 usually have their status extended through their employer’s Form I-129 petition, not Form I-539. The dependents of those workers, however, often do use I-539. If you are unsure whether the form applies to you, that is worth confirming before you file, because submitting the wrong form wastes time you may not have.
How much does Form I-539 cost in 2026?
The filing fee depends on how you file. As of 2026, the fee is $370 to file online and $420 to file by paper, a $50 difference that reflects the paper surcharge USCIS introduced under its 2024 fee rule. You can confirm the current amount on the official USCIS Form I-539 page before you submit, since fees can change.
Many applicants also owe an $85 biometric services fee. This generally applies to applicants between the ages of 14 and 79, while children under 14 and adults over 79 are typically exempt. When several family members file together as co-applicants on one form, each person who needs biometrics pays the biometric fee. Adding up the filing fee plus biometrics for everyone on the application avoids an unwelcome surprise. Because fee questions come up constantly, our note on recent USCIS processing changes is a useful companion when you are budgeting time and money.
What is the deadline to file Form I-539?
You must file before your current status expires, and that date is on your Form I-94 arrival record, not your visa stamp. This is the single most important deadline in the entire process. USCIS recommends filing for an extension at least 45 days before your authorized stay ends, which gives the agency time to act and gives you a cushion if something needs to be corrected.
People confuse the visa stamp in their passport with their I-94 expiration, and that confusion is costly. The visa is your entry document; the I-94 sets how long you may stay on this particular trip. Always file based on the I-94 date. If you have lost track of yours, you can retrieve it from the CBP I-94 website before it is too late.
Can you stay in the United States while Form I-539 is pending?
In many cases, yes, if you filed on time. When you submit a timely, non-frivolous extension or change of status request before your current status expires, you generally may remain in the United States while USCIS decides, even if your prior status lapses during the wait. This protection depends on having filed before the deadline.
That said, a pending I-539 does not give you new benefits before approval. An extension request does not let you work without separate authorization, and a change of status request does not let you begin the new activity until it is granted. Acting too early, such as starting school or work before approval, can undermine the very application you are waiting on. Patience here protects you.
What are the most common Form I-539 mistakes?
The mistakes we see most often are filing after the I-94 expired, paying the wrong fee, leaving the biometric fee out, and submitting inconsistent or incomplete documents. Each of these can lead to a rejection or a denial, and a denial after your status has expired can quickly turn into a serious problem. Filing late is the most damaging of all, because the on-time protection that lets you stay during processing disappears.
Inconsistency is the quieter danger. When the dates, names, or status details on your I-539 do not match your I-94, your passport, or your earlier filings, USCIS may question the whole application. Reviewing everything for consistency before you file, and keeping copies of what you send, prevents most of these problems. If you want a second set of eyes on your packet, you can request a free pre-evaluation and we will review it with you.
Frequently asked questions
Can I file Form I-539 online? Many applicants can. USCIS offers online filing for eligible I-539 categories, and filing online costs less than paper. Check the online eligibility page to confirm your category qualifies.
Does filing I-539 let me work? No. An extension or change of status does not authorize employment by itself. Work authorization comes through a separate process tied to your specific status.
What if my I-94 already expired? Filing after expiration is risky and may not be accepted, and any time out of status carries consequences. Talk to an attorney right away rather than filing on your own.
Can my family be included on one I-539? Often yes. A spouse and children can sometimes be co-applicants on a single form, though each may owe a biometric fee. The instructions explain who can be grouped together.
