How to Apply for an ESTA: Step-by-Step (and Common Mistakes)
By The Visit America editorial team · Last verified July 5, 2026
Apply only at the official site, esta.cbp.dhs.gov, at least 72 hours before you travel. You’ll need your e-passport, answer eligibility questions, and pay the fee. Approval is usually fast but isn’t guaranteed.
Use the official site only
Apply at esta.cbp.dhs.gov. Many search results are third-party “ESTA” sites that fill in the same government form for you and add a large service fee. They are not the government and can’t give you anything the official site doesn’t. Check the address bar for esta.cbp.dhs.gov before entering any details.
Step by step
1. Have your electronic passport ready. 2. Go to esta.cbp.dhs.gov and start a new application. 3. Enter your passport and personal details exactly as printed. 4. Answer the eligibility questions honestly. 5. Provide your travel and contact details. 6. Review carefully — a mistyped passport number is a common cause of problems at check-in. 7. Pay the fee. 8. Note your application number and check the status; approval can take up to 72 hours.
Apply early — and don’t assume
Apply at least 72 hours before departure; most approvals are quicker, but not all. An approved ESTA is generally valid for two years or until your passport expires, and covers multiple trips — but you must reapply if you get a new passport or your details change.
An approval authorises you to board and travel to a US port of entry. It is not a guarantee of admission — a CBP officer decides that on arrival.
