United States
Visas and entry
Most British citizens visiting for up to 90 days use the Visa Waiver Programme and need an approved ESTA before they travel. Apply only on the official US government site: other sites charge extra.
Passport
You need an electronic passport (with the chip symbol on the cover), valid for the length of your stay.
At the border
Apply for the ESTA at least 72 hours before you fly. It costs US$40.62 (from October 2026) and lasts two years, or until your passport expires if that's sooner. A new passport needs a new ESTA.
Health cover
The GHIC is not valid here. Travel insurance with full medical cover, declaring every pre-existing condition, is essential.

Tip for grandparents
US medical bills are among the highest in the world. Check that your insurance covers several million pounds of medical costs and declares every condition, especially if you're visiting family for a long stay.
Check your cover before you go: travel insurance in your 60s, 70s and 80s.
