New Travel Requirements (Western Hemisphere Initiaive)
"AIR TRAVEL

* All U.S. citizens traveling by air are required to present a passport book to enter or re-enter the United States.

LAND AND SEA TRAVEL

The following summarizes information available on the Department of Homeland Security’s website.

* CURRENTLY:
All U.S. citizens must show proof of identity and proof of U.S. citizenship when entering the United States from Canada, Mexico, Bermuda and the countries of the Caribbean by land or sea.

Acceptable documents include: U.S. Passport Book, U.S. Passport Card, or other document approved by the Department of Homeland Security.

U.S. citizens who do not have a single document verifying identity and citizenship must present both an identification and citizenship document; for example, a driver’s license and a copy of a birth certificate or naturalization certificate.

* LATER:
On June 1, 2009, the U.S. government will implement the full requirements of the land and sea phase of WHTI. The proposed rules require most U.S. citizens entering the United States at sea or land ports of entry to have a passport, passport card, or other travel document approved by the Department of Homeland Security.

o CHILDREN: U.S. citizen children under the age of 16 will be able to present the original or copy of their birth certificate, or other proof of U.S. citizenship such as a naturalization certificate or citizenship card.

Groups of U.S. citizen children ages 16 through 18, when traveling with a school or religious group, social organization, or sports team, will be able to enter under adult supervision with originals or copies of their birth certificates or other proof of citizenship.
