Yes, you may request to extend your stay in the U.S. as a visitor by filing Form I-539 with USCIS before your current authorized stay expires. You must demonstrate a valid reason for the extension, proof of financial support, and show that you intend to depart the U.S. at the end of your extended visit.

Yes, if you're in the U.S. on a visitor visa (B-1/B-2), you can apply to extend your stay. You’ll need to file Form I-539 with USCIS before your current stay ends and explain why you need more time. If they approve it, you can stay longer but don’t wait until your visa expires to apply.

You can extend your visitor stay in the U.S., but it requires proper timing and documentation. The application should be filed while your current I-94 admission record is still valid, and you’ll need to explain your reason for needing more time such as medical treatment, family emergencies, or delayed return travel. You cannot overstay if the extension is denied.
