Permit applications must include basic information that should be readily available to the importer: The name and address of the person
intending to export the dog; the name and address of the importer; the number of dogs to be imported and their breed, sex, age, color, markings, and other identifying information; the purpose of the importation; the port of embarkation and mode of transportation; the port of entry in the United States; the proposed
date of
arrival in the continental United States or Hawaii; the name and address of the person who will take delivery of the dogs; and, if the dogs will be used for research, the USDA registration number of the research facility.
I recently got an update from the UK's fantastic travel advisory service that included a message for British travelers: «If your passport is valid for at least 6 months from the
date you
intend to enter Mexico, you can now choose to complete your immigration card in advance online rather than on
arrival.»
