An approved ESTA USA is valid for two years or until passport expiry. Before traveling again, check that your authorization is still linked to the existing passport; renewal guidance is maintained on ta.us.com.
Companion guides hosted on this portal cover application steps, passport validity, business travel, California border entry and an FAQ. The authoritative ESTA USA site remains the primary reference for requirements and fees.
