AIR TRAVEL
 

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.
LAND AND SEA TRAVEL
The following summarizes information available on the Department of Homeland Security’s website.

  • CURRENTLY: 
    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.
  • 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 WHTI-compliant document. 

Note: The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory.

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 to begin production of the passport card in June, and be in full production in July. 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 WHTI
The Western Hemisphere Travel Initiative is a result of the Intelligence Reform and Terrorism 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 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.
