| Just to add to Scott’s answer a bit.
As he said, yes, you now need a passport to travel by AIR or SEA to Canada, Mexico or the Caribbean.
And as of June 30, 2009 (but possibly as early as Jan 1, 2008), you will need a passport to cross those borders by car.
But to travel by plane from one US state to another, does NOT require a passport now, nor in the future. |
