Essential Information for U.S. Visitors to Waterton Park
On June 1, 2009, a new American law known as the Western Hemisphere Travel Initiative (WHTI) will require U.S. citizens 16 years of age or over who re-enter the United States by land and sea to have a passport or other appropriate secure document like a NEXUS card.
Until this date arrives, U.S. citizens 19 years and older who enter the U.S. at land and sea ports of entry from within the Western Hemisphere will need to present government-issued photo ID, such as a driver’s license as proof of identity, along with proof of citizenship, such as a birth certificate or naturalization certificate, or a passport. Children age 18 and under will be able to enter with proof of citizenship. Verbal claims of citizenship and identity alone will not be sufficient to establish identity and citizenship for entry into the United States.
