Filing immigration paperwork isn’t always straightforward, especially when it comes to extending your stay or changing your visa type while inside the U.S. That’s what Form I-539 is used for. Whether you’re a tourist wanting to extend your B-2 visitor status, an H-4 dependent spouse, or an F-1 student’s family member, understanding how to file Form I-539 online or by mail is crucial for maintaining your legal status.
In this guide, we’ll break down how to file Form I-539 online, how to fill out the form correctly, where to send it if you’re mailing, and everything else you need to know to get your application moving in the right direction.
What is Form I-539 and Who Can File I-539?
Form I-539, officially called the Application to Extend/Change Nonimmigrant Status, allows certain nonimmigrants to stay longer in the U.S. or shift into a different nonimmigrant visa category, without having to leave the country.
This form is commonly used by:
- Tourists on a B-2 visa who want to extend their stay
- H-4 and L-2 dependents (spouses or children)
- F-2 dependents of F-1 international students
- Individuals looking to switch from one visa category to another (for example, B-2 to F-1)
Some applicants can file Form I-539 online. USCIS allows form I-539 online filing through its official website. If you’re eligible, this is often the easiest and fastest way to apply.
When you file Form I-539 online, you’ll get instant confirmation and be able to track your case status as it moves through the system. The system also reduces common mistakes by guiding you through each part of the I-539 online form step-by-step.
However, certain circumstances may require paper filing, such as when you’re including multiple family members on a single application or when specific supporting documentation cannot be uploaded digitally. Before choosing your filing method, verify whether you can file Form I-539 online based on your specific situation and visa category.
How Do I Fill Form I-539 Correctly?
One of the most important parts of this process is making sure your form is filled out completely and correctly. Even small errors can lead to delays or denials. The instructions to fill out the I-539 form require careful attention to detail and a thorough understanding of each section’s requirements.
Here are the essential steps for how to fill out Form I-539:
Part 1 (Information About You): Make sure your full legal name is entered exactly as shown in your passport. That includes any middle names or suffixes.
Part 2 (Application Type): Indicate clearly whether you are applying for an extension of your current stay or a change to a new nonimmigrant category.
Part 3 (Processing Information): Add your country of birth and citizenship, along with your current immigration status.
Part 4 (Additional Information): Answer all the yes/no questions honestly, including ones about immigration history and any criminal background.
Part 5 (Applicant’s Statement and Certification): This is where you certify that everything is accurate. Make sure you sign and date this part.
Here are some common mistakes to avoid when filling out the I-539 form:
- Leaving sections blank instead of writing “N/A”
- Mismatched dates that don’t align with your I-94 record
- Missing documents
- Forgetting to sign
If you’re using the I-539 online form, the system often catches these errors before you submit. That’s one reason many people choose to file Form I-539 online instead of by mail.
Where Do I Send Form I-539 If I’m Filing by Mail?
If you’re not filing Form I-539 online, you’ll need to mail your application. But where to send Form I-539 depends on a few key things:
- The type of visa you’re on
- What you’re applying for (extension or change of status)
- Your current U.S. address
USCIS provides updated filing addresses every year. If you’re unsure where to mail Form I-539 or where to send the I-539 form, don’t guess; check the USCIS website for the most current list.
Make sure you’re also using the correct address, depending on whether you’re sending your form via USPS or a courier like FedEx or UPS. This small detail can make a big difference in how quickly your application is received and processed.
How Can I Avoid Delays or Rejections?
There are a few key instructions for Form I-539 that applicants should follow closely. Filing the I-539 form properly means paying attention to both the details and the bigger picture.
- Submit complete supporting documentation: Include your I-94 record, passport copy, and documents that justify your request.
- Pay correct fees: Double-check the current I-539 filing fee. As of July 2025, the online filing fee is $420, while the paper filing fee is $470. Use approved payment methods.
- Provide certified translations: Submit certified English translations for any foreign language documents.
- Submit required photographs: If your application requires photos, follow USCIS size, quality, and background requirements.
- File on time: Ideally, you should file Form I-539 at least 45 days before your current status expires.
- Complete every section: Answer all applicable questions. Write “N/A” in sections that don’t apply to you.
- Don’t forget to sign: The Form I-539 won’t be processed without your signature. Also, if you’re including family members, make sure everyone signs where needed.
What Happens After You File Form I-539?
Once you’ve submitted Form I-539, whether you chose to file Form I-539 online or mail a paper application, USCIS will send you a receipt notice. This notice is proof that your application was received and is being processed. It also contains your receipt number, which you can use to track your case using the USCIS online system.
In many cases, especially if you’re requesting a change of status or certain types of extensions, USCIS may schedule you for a biometrics appointment. This means you’ll need to visit a USCIS Application Support Center to provide your fingerprints and have your photo taken. It’s a required step, and skipping it could lead to delays or, worse, a denial.
How Long Does It Take to Process Form I-539 in 2025?
There’s no fixed processing time for the I-539 form. How long it takes depends on several factors, including which service center is handling your case and what type of request you submit. For most people filing the I-539 form, processing times range from 3 months to 12 months or more.
You can check the estimated timeline for your specific case using the Check Case Processing Times tool on the USCIS website. Just make sure you select the correct form category and service center. Keep in mind that USCIS may also request additional documents, which can slow things down.
Can I File Form I-539 Twice?
Yes, you can file the I-539 form more than once, but not simultaneously for the same beneficiary. You can’t have two pending applications for the same person at the same time. However, if you’ve already received a decision on a previous application or your situation has changed, you can submit a new one.
Make sure your initial application has been resolved before filing again unless USCIS specifically allows concurrent filings in your case.
What’s the Best Way to File Form I-539 in 2025?
The best method depends on your specific situation. In general, Form I-539 online filing is faster and more convenient for most people. When you file Form I-539 online, you get immediate confirmation, real-time tracking, and fewer chances of basic errors. The system guides you through how to fill out Form I-539 and catches common mistakes before you submit.
However, paper filing still works better in some scenarios, especially if you’re including multiple dependents or need to submit a large packet of physical evidence. If you’re unsure which route to take, review the latest Form I-539 instructions on the USCIS site before deciding.
