Prior to next week's launch of a new online immigration system, the U.S. Embassy in Tokyo made its final attempt Thursday to call on Japanese to preregister before they head off for a trip to the States.

The embassy has been promoting introduction of the Electronic System for Travel Authorization amid concerns there will be confusion at airports among travelers who don't know about the new system.

"What we are trying to do is to bring in the latest technology there is so we can make it as easy as possible for people to get into the U.S.," U.S. Ambassador Thomas Schieffer said. "What we want is more visitors to come to America and what we're trying to do is to make that easier for them to do."
