Since Oct 1, 2022, VWP travelers entering the U.S. by land must have an approved ESTA. If you’re not within a current 90‑day admission, you may also pay the I‑94W fee at the port.

Certain travel histories (e.g., **Cuba on/after Jan 12, 2021**) make travelers ineligible for VWP, requiring a visa instead.
