For the purposes of international travel and trade, most foreign countries require that the health certificate be issued (completed, signed, dated) by a USDA-accredited veterinarian before being endorsed (countersigned and embossed/stamped) by APHIS.
A USDA-accredited veterinarian has completed formal training from the National Veterinary Accreditation Program (NVAP) in the State(s) they are licensed to practice medicine in. Accreditation is State-specific and voluntary (not all veterinarians are accredited).
Make sure your USDA-accredited veterinarian is accredited in the State you're seeing them in! APHIS cannot endorse your health certificate if your veterinarian is not accredited in the State where they're practicing medicine. Contact your State’s NVAP coordinator to confirm your veterinarian’s accreditation status.
