Visitors from close allied countries like Japan and Britan will soon have to register personal details online at least three days before arrival.

The United States will begin implementing the changes in August. Online registration will be compulsory for all visa-free travel by Jan. 12.

There are currently 27 countries whose citizens are not required to obtain visas for U.S. entry, When U.S began discussing the online registration rule last year, European businesses worried that business travel could be hampered.

But Chertoff said the system will simplify visa-free travel, because visitors will only be required to register online once every two years instead of filling out forms each time they travel.
