Yes, you can request an extension of your B-2 visitor visa by filing Form I-539 (Application to Extend/Change Nonimmigrant Status) with USCIS. You must apply before your current authorized stay expires, and provide a valid reason for the extension, along with supporting documentation and proof of financial support.

B-2 visa holders may apply for an extension of stay if they need more time for tourism or personal reasons. To do this, you must file Form I-539 with USCIS, usually at least 45 days before your current I-94 expiration date. Approval is not guaranteed and depends on your ability to show that your visit remains temporary and that you will depart the U.S. afterward.

Yes, it's possible to extend your B-2 stay, but you must apply while your visa status is still valid. You’ll need to explain why the extension is needed, show you can financially support yourself during the extended stay, and prove you still intend to return home. Extensions are generally granted for up to six additional months, if approved.
