The US Congress has continued the discussion on the date of implementation of the Western Hemisphere Travel Initiative. Right now, it looks like those air passengers returning to the US will need to present valid passports starting January 8, 2007.
This change will not include Puerto Rico and the US Virgin Islands.
Cruise passengers returning from the region will have an extended period, possibly until mid-2009, to meet the passport requirement.
