President Bush recently announced that the visa waiver program, for travel to the USA without a visa, will be extended to seven more countries.  There are currently 27 countries in the visa waiver program that allows its residents to visit the USA for up to 90 days without obtaining a visa.  By mid November 2008, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, South Korea and Slovakia will join that list.

Residents from these seven countries will be able to visit the USA for up to 90 days without a visa as long as they posess a biometric passport and they register online through the Electronic System for Travel Authorization (ESTA). 

This new online travel registration system is now fully active, and available for all visa waiver visitors to the USA.  So far, it has been a voluntary convenience, but in January of 2009 it will become mandatory for all visa waiver visitors.

You can get information about ESTA in nine languages at this US Customs and Border Patrol webpage.
