I wonder how long it will take other countries to respond by finding ways to get inbound US passengers to pay up! - The Travel Blogger
The Electronic System for Travel Authorization (ESTA) scheme replaces the old arrangement whereby passengers needed to fill out a green card to enter the US. The new scheme was introduced in January last year, but becomes mandatory from next Wednesday. It applies to all 35 countries that enjoy visa waiver status. An approved ESTA is valid for two years and can be used for multiple entries into the US. More UK Telegraph
