US Visa waiver program moves online
In a major change to the United States visa waiver program (VWP), Irish and UK citizens will need to apply online and in advance of travelling, this came into effect on January 12, 2009.
Once approved, an ESTA is valid for multiple entries over two years – or until the holder’s passport expires. US authorities are keen to highlight the fact that the information required of passengers is no different to that on the old Green I94 form and that, in the vast majority of cases, a message indicating authorisation to travel – or not – will be instant.
Those planning to travel to the US are encouraged to apply for authorisation as far in advance as possible and no later than 72 hours before travelling, although “there will be accommodations for those flying at the last minute or in emergencies”.
The ESTA itself is an electronic authorisation matched to a passport – rather than a physical endorsement or certificate – and can be applied for even without the passenger knowing their exact travel and destination details. Those in possession of an ESTA should update their travel details (via the same website) for each subsequent journey to the US during its two-year validity.
