Generally a passport is not required for Canada,
Mexico, and the Caribbean (except for Barbados) as long
as you have an original birth certificate (not a photo
copy). If you do not have an original copy of your
birth certificate and are not sure where to obtain one,
go to www.vitalrec.com. For Barbados and most other
foreign countries, a passport is necessary. Even an
infant must have a passport. Some countries require
that the passport expiration date is at least six
months beyond your return date.
