Some Countries require that a veterinarian certificate issued in the United States have an official USDA stamp.
The following is the procedure for acquiring one.
Have your veterinarian complete the EU form 998 or other form for the country you are visiting.
Your veterinarian will complete and sign the form including the vaccination information and stating that the pet is parasite free and in good health.
Take the original of the form to the APHIS/USDA vet office in your state and they will endorse and stamp them.
The fee is $24 per form...more than 1 animal can be listed on a form. If your vet uses separate forms for each animal; it will be $24 per form.
If there is not a State office located nearby you can send the forms by mail.
Include: The original of the form
Payment in the amount of $24.00 per form
A self-addressed, stamped envelope for returning the form to you.
Each state has an APHIS/USDA state veterinarian.
