Tourist Visa in the USA Expires: I-94, I-539 Extension, Overstay, and 3/10 Year Bans (2026)

The legality of your stay is determined by the date on the I-94, not the visa's validity; ESTA has no extensions (emergency satisfactory departure for up to 30 days), while for B-2 you must file I-539 (470/420 USD) before the deadline, with over 180 days resulting in a 3-year ban and over a year leading to a 10-year ban, alongside changes in 2025 and 2026 regarding registration, ESTA fees, and asylum fees.
