United States - Passport & Travel Document Requirements
All U.S. citizens including children must present a passport or other approved travel document when entering the United States by air.

Land and Sea Travel
The following summarizes information available on the U.S. Department of Homeland Security's website.
Beginning June 1, 2009
U.S. citizens entering the United States at sea or land ports of entry are required to have documents that comply with the Western Hemisphere Travel Initiative (WHTI), most commonly a U.S. passport, a passport card, a trusted traveler card such as NEXUS, SENTRI or FAST, or an enhanced driver's license. See the complete list of WHTI-compliant documents.

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: Passport card applications are currently being accepted in anticipation of land border travel document requirements. Based on current projections, we expect the passport card to be in full production beginning in July 2008. We will provide additional updates as available. Once in production, the passport card it will only be valid for land and sea travel between the U.S. and Canada, Mexico, the Caribbean region, and Bermuda.

About Western Hemisphere Travel Initiative
The Western Hemisphere Travel Initiative is a result of the Intelligence Reform and Prevention Act of 2004 (IRTPA), requiring all travelers to present a passport or other document that denotes identity and citizenship when entering the U.S.
The Department of Homeland Security (DHS) announced on February 22 its intent to propose, as part of the Notice of Proposed Rulemaking on the Western Hemisphere Travel Initiative (WHTI), significant flexibility regarding travel documents required for U.S. and Canadian children as part of WHTI requirements for U.S. land and sea border entry in 2008.
The goal of the initiative is to strengthen U.S. border security while facilitating entry for U.S. citizens and legitimate foreign visitors by providing standardized documentation that enables the Department of Homeland Security to quickly and reliably identify a traveler.
