UPDATE - 5/12/08: Western Hemisphere Travel Initiative
ALL PERSONS traveling by air outside of the United States are required to present a passport or other valid travel document to enter or re-enter the United States.
You may be required to present additional or different travel documents when entering foreign countries, including countries in the Western Hemisphere. Before you travel, make sure you know the entry requirements of the country you plan to visit. See Country Specific Information for more information on the country you are traveling to.
U.S. citizens on closed-loop cruises (cruises that begin and end at the same port in the U.S.) will be able to enter or depart the country with proof of citizenship, such as a birth certificate and laminated government issued picture ID, denoting photo, name and date of birth. A U.S. citizen under the age of 16 will be able to present either an original or a certified copy of his or her birth certificate, a Consular Report of Birth Abroad issues by DOS, or Certificate of Naturalization issued by U.S. Citizenship and Immigration Services.
LAND AND SEA TRAVEL:
The following summarizes information available on the Department of Homeland Security's website.
U.S. citizens need to present either (a) a passport, passport card (available in spring 2008), or WHTI-compliant document; or (b) a government-issued photo ID, such as a driver's license, along with proof of citizenship, such as a birth certificate.
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 WHTI-compliant document.
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 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. See the Department of Homeland Security's GetYouHome.gov for more information on the changing travel requirements.
The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory.
U.S. territories include American Samoa, Guam, Northern Mariana Island, Puerto Rico, Swains Island and U.S. Virgin Islands.
U.S. PASSPORT AND WHTI COMPLIANT DOCUMENTS:
U.S. Passport: U.S. citizens may present a valid U.S. passport when traveling via air, land or sea between the U.S. and the aforementioned Western Hemisphere countries.
The Passport Card: U.S. citizens may begin applying in advance for this new, limited-use, wallet-size passport card beginning February 1, 2008. We expect cards will be available and mailed to applicants in spring 2008. When available it will only be valid for land and sea travel between the U.S. and Canada, Mexico, the Caribbean region, and Bermuda.
WHTI-Compliant Travel Documents for U.S. citizen travel via land or sea, as of January 31, 2008:
For further information see U.S. Customs and Border protection.
Effective Jan. 31, 2008, New Requirements for Entry at Land and Sea Ports from Canada
Effective Jan. 31, 2008, U.S. and Canadian citizens (19 and older) will be required to present proof of citizenship, such as 1) a passport or 2) a birth certificate or naturalization certificate supported by a government issued photo ID, when entering the United States through land and sea ports of entry from Canada. Children ages 18 and under are only required to present proof of citizenship (without ID), such as a birth certificate, naturalization certificate or passport. If a birth certificate is presented, it must be a certified birth certificate issued by the city, county or state. A photocopy of a birth certificate will only be accepted by U.S. Customs and Border Protection (CBP) if the original has been sent to the Department of State in support of a passport application. In such case, the traveler must obtain and provide proof of passport application. These changes are significant as compared to the current and long-standing policy that allows CBP officers to accept oral declarations of citizenship from U.S. and Canadian citizens seeking entry into the United States through a land or sea border. Effective Jan. 31, 2008, oral declarations will not be accepted.
Eventually, at an unspecified date in mid-2008, the Department of State will require passports, or soon-to-be announced passport alternatives, from ALL travelers at ALL points, including air, land and sea, within the Western Hemisphere. Prior to the effective date, the State Department intends to make available a Passport Card, which is specifically designed for land and sea travel from neighboring countries. The primary advantages of the Passport Card are that it will be less expensive and smaller than a traditional passport. In addition, several states including Washington, Vermont and New York are creating an Enhanced Driver_s License that will, according to the CBP, also fulfill the proof-of-citizenship requirement at land and sea borders. Further details of these alternative products are unknown. However, CBP says that ample notice of the exact date of implementation will be provided to ensure travelers can obtain the appropriate documents.
Since passports are the gold standard for entering and exiting the country from all foreign destinations, ALL travelers, including those traveling by land or sea in the Western Hemisphere, should be obtain, and travel with, a passport. The current turnaround time for a passport is four to six weeks.
UPDATE - 10/1/07: U.S. citizens traveling by air to Canada, Mexico, the Caribbean, and Bermuda

About the Initiative:
The Western Hemisphere Travel Initiative (WHTI) requires all citizens of the United States, Canada, Mexico, and Bermuda to have a passport or other accepted document that establishes the bearer�s identity and nationality to enter or re-enter the United States from within the Western Hemisphere.
The travel document requirements make up the departments of State and Homeland Security�s Western Hemisphere Travel Initiative (WHTI). This change in travel document requirements is the result of recommendations made by the 9/11 Commission, which Congress subsequently passed into law in the Intelligence Reform and Terrorism Prevention Act of 2004.
This travel initiative is being implemented in two phases. The first phase will be for air travel, and the second for land/sea travel.
