For Current Passport Policy:
For specific information with respect to the current policy associated with U.S. citizen air travel to Canada, Mexico and the
Caribbean, please follow the link below to the webpage of the U.S. Department of State. http://travel.state.gov/travel/cbpmc/cbpmc_2223.html
If you do not have a valid passport, and are considering travel outside the
U.S. within the coming year, I would strongly encourage you to begin the application process as soon as possible.
