It won't be quite as easy to travel by car to Mexico or Canada beginning June 1, according to a published report.
On that date, all adult U.S. citizens will need a passport to cross the border, U.S. officials say. Children 16 years old and younger will still be able to use their U.S. birth certificates as proof of citizenship, reported the North County Times.
Officials said getting Americans to use passports will improve border security. The requirement is part of a 2004 law passed by Congress called the Western Hemisphere Travel Initiative.
