Hi gooner,
VERY IMPORTANT!!! you need to visit a website and complete the online application, otherwise you ain’t going to be allowed to board your plane. your travel agent should have advised you of this (I’m a travel agent myself 🙂 )
Here’s what we advise our customers:
“Traveller’s to the US under the Visa Waiver Programme will now have to apply in advance of travel for a travel authority using ESTA website https://esta.cbp.dhs.gov Once granted, a travel authority is valid for two years. Before each new trip to theUS, traveller’s must update their travel plans and address details via the ESTA website.
For those passengers transiting in the US you will also need to apply.
It is the individual travellers responsibility to make the application and to ensure that you have a valid travel authority before travel. At present Intrepid Travel will not be able to identify passengers eligibility for ESTA travel authorisation.
Passengers should apply for a travel authority at least 72 hours before departure. In usual circumstances a response (ESTA granted or denied) is given in seconds. For a small minority of passengers the decision will take up to 72 hours. Currently there is no fee to apply for a travel authorization.
The Visa Waiver Program allows foreign nationals from certain countries to travel to the United States for business or pleasure, for stays of 90 days or less without obtaining a visa. For more information please visit: https://esta.cbp.dhs.gov “
Have fun in Costa Rica 🙂
