Passport Info

U.S. citizens traveling to Canada, Mexico, Bermuda or countries in the Caribbean region who have applied for, but not yet received passports, can re-enter the United States by air by presentation of a government issued photo identification and Department of State official proof of application for a passport through September 30, 2007.  The federal government is making this accommodation for air travel due to longer than expected processing times for passport applications in the face of record-breaking demand.

Adults who have applied for but not yet received a passport should present government-issued photo identification and an official proof of application from the U.S. Department of State. Children under the age of 16 traveling with their parents or legal guardian will be permitted to travel with the child’s proof of application status. This accommodation applies to all American citizens who apply for passports, until September 30, when this accommodation period ends. U.S. citizens with pending passport applications can obtain proof of application at: http://travel.state.gov/passport/get/status/status_2567.html.
