The US Visa Waiver Program allows foreign nationals from certain countries, including New Zealand and Australia, to visit the U.S. for a maximum of 90 days without obtaining a visa.
From January 12, 2009, travellers visiting the U.S. under the Visa Waiver Program will have to apply for authorization to enter the U.S. prior to their trip using the Electronic System for Travel Authorization (ESTA).
Simply apply online at ESTA for authorization at least 72 hours prior to your journey. A cost of 14 USD will apply.
ESTA travel authorization is valid for up to two years or until your passport expires, whichever comes first. Travellers who fail to obtain approval prior to check-in may be denied boarding. Passengers may also experience delayed processing or denied admission at a U.S. port of entry. Learn more and a full list of countries participating in the Visa Waiver Program.
