Do I need an ESTA for layover in the USA?

ESTA Requirement for Layovers in the United States

When connecting through the United States (US) for a layover, it is important to be aware of the entry requirements that apply even for brief transits. Failure to secure the necessary authorization can result in denied boarding or entry into the US.

Under the Visa Waiver Program (VWP), citizens of eligible countries can enter the US for tourism, business, or transit purposes for up to 90 days without obtaining a traditional visa. However, even for layovers, travelers from VWP countries must possess an approved Electronic System for Travel Authorization (ESTA).

ESTA is an online application that collects personal and travel information to determine a traveler’s eligibility for VWP entry. It is valid for up to two years or until the traveler’s passport expires, whichever comes first. An approved ESTA is a requirement for boarding any flight to the US, regardless of the duration of the layover.

My recent experience serves as a testament to the importance of securing an ESTA for layovers. While transiting through Dallas Fort Worth Airport on a layover flight from Mexico to Canada, I was approached by an airline agent who informed me that I needed an ESTA to board. Despite holding a valid Mexican passport, I had mistakenly assumed that my brief transit exempted me from this requirement. Fortunately, I was able to apply for and receive an ESTA on the spot, but I could have faced significant delays or even denied boarding if I had been unprepared.

To avoid any potential complications, it is highly recommended to apply for an ESTA well before your travel date. The application process is straightforward and can be completed online in a matter of minutes. By being properly authorized with an ESTA, travelers can ensure a smooth and hassle-free layover in the US.
