I-539 Checklist: Extend or Change Nonimmigrant Status

Immigration Attorney and Nonimmigrant Status Resource

Streamline your Form I-539 (Application to Extend/Change Nonimmigrant Status) with our comprehensive document checklist. The I-539 is used to extend your stay in the same nonimmigrant category (e.g., extend B-2 visitor status or F-1 student status) or to change to a different nonimmigrant category (e.g., change from B-2 to F-1) while in the United States. You must file before your current period of stay expires—USCIS recommends filing at least 45 days before expiration and generally not more than six months early. This checklist helps immigration attorneys, international students, visitors, and dependents gather the right documents: I-94 for each applicant, category-specific evidence (e.g., I-20 and financial proof for F-1 extension; written statement for B-2 extension), and Form I-539A for each co-applicant. Certain employment-based extensions use Form I-129 instead of I-539.

Frequently Asked Questions

What is Form I-539 used for?
Form I-539 is the Application to Extend/Change Nonimmigrant Status. Use it to (1) extend your stay in your current nonimmigrant category (e.g., extend B-2 or F-1), or (2) change to a different nonimmigrant category while in the U.S. (e.g., change from B-2 to F-1). You must be in valid status when you file and before your authorized stay expires.
When should I file the I-539?
File before your I-94 or current period of stay expires. USCIS recommends filing at least 45 days before expiration. Do not file more than six months before your stay expires unless the instructions allow it. If you file on time, you may be able to stay while the application is pending (authorized stay); check the instructions for your category.
Do I use I-539 or I-129 for my extension?
Form I-539 is used for many nonimmigrant categories (B-1/B-2, F-1, M-1, and many dependent categories). Form I-129 is used for certain employment-based categories (e.g., H-1B, L-1, O-1). Check the USCIS I-539 page and form instructions to confirm which form applies to your status.
What evidence do I need for a B-2 extension?
For a B-2 (or B-1) extension you typically need your I-94, a written statement explaining the reason for the extension (e.g., medical, family, continued tourism), and evidence supporting that reason. Proof of funds and ties abroad may strengthen your case. Our checklist covers this and other categories.
