Does an approved ESTA guarantee entry to the USA?

No. An ESTA only authorises you to travel to the USA under the Visa Waiver Program. The final decision on admission is made by the CBP officer during the in-person interview at the airport.

What questions does the CBP officer ask at border control?

Typical questions cover the purpose of your trip, how long you will stay, where you are staying, your return flight, your occupation and the funds you have available.

What is secondary inspection?

Secondary inspection is a second, more detailed check to which travellers may be referred from the first checkpoint. Your details and documents are examined more closely there before a decision on admission is made.

US Border Control: the CBP Interview at the Airport

On arrival in the USA, every travellergoes through an in-person check by an officer of U.S. Customs and Border Protection (CBP). An approved ESTA does not guarantee entry — the final decision is made by the officer at the inspection booth. This page explains how the interview works, which questions are asked and what secondary inspection means.

Who is checked? Everyone — without exception

Unlike some countries, the USA has no fully automated passport check that replaces the conversation: every arriving traveller is questioned in person by a CBP officer. This also applies to travellers with an approved ESTA.

Important: an ESTA is a travel authorisation, not a guarantee of entry. The final decision on whether you may enter the USA is made by the CBP officer on arrival. To find out exactly what an approval means, see Checking your ESTA status.

The CBP interview: questions to expect

The interview is usually short. The officer wants to confirm that your trip matches the details in your ESTA application. Typical questions include:

Purpose of the trip — tourism, business, visiting someone?
Length of stay — how long will you be in the USA?
Accommodation — where are you staying (hotel, friends, family)?
Return flight — when and where are you flying back to?
Occupation — what do you do for work in your home country?
Funds — how much money are you carrying, or how are you paying for the trip?

Tip: answer briefly, calmly and truthfully. Your answers should match the details in your ESTA application.

Secondary inspection: the second check

In some cases the officer refers travellers from the first checkpoint to what is called secondary inspection— a second, more detailed check in a separate area. Your details and documents are examined more closely there before a decision on admission is made.

A referral is not an accusation — at first it simply means the officer needs more time for the check
Expect extra waiting time and further questions about your trip
The same applies here: stay calm and answer truthfully

Documents to keep to hand

Your ESTA is linked electronically to your passport and does not need to be printed. Even so, it helps to have evidence for your answers ready during the interview:

A valid e-passport (the one your ESTA is linked to)
Return or onward flight booking — in case you are asked about your return
Address of your accommodation (hotel booking or your hosts' address)
Evidence of the purpose of your trip and your funds, if asked

For a list of documents needed for the application itself, see Required documents.
