📌 Key points to remember

🛄 Why is an ESTA mandatory for a layover in the United States?

Unlike many other countries, the United States does not have a true international transit zone. Connecting passengers generally have to go through immigration control before continuing their journey.

🔹 Transit in the United States is considered entry into the country

Even if you stay only a few hours in the airport before catching another flight, the U.S. authorities consider this stopover as entry into U.S. territory.

In practical terms, this means that you will need to:

• ✈️ Get off your plane.
• 🛄 Go through immigration control.
• 🧳 Collect your checked baggage if necessary.
• 🔎 Go through another security check.
• ✈️ Then board for your final destination.

Consequently, travelers benefiting from the Visa Waiver Program must have a valid ESTA before departure.

In the vast majority of cases, the answer is no.

Even for:

• Asia or Oceania;

ESTA generally remains mandatory if your itinerary includes a layover in the United States.

Without valid travel authorization, the airline may refuse to let you board at the departure airport.
