The online form replaces the onboard paper and customs entry requirements for all passport holders of visa waiver countries. Electronic Travel Authorization (ESTA) application forms became mandatory on January 12, 2009, to reinforce security.

How long is my ESTA approval good for? Your ESTA authorization is generally valid for multiple trips over a period of two years (starting the date that you are approved) or until your passport expires, whichever comes first*. This means that as long as you received an ESTA authorization to travel, you do not have to reapply during the validity period.
