What type of work permit/visa is needed for a trained horse specialist?
My husband is a specialist in training gaited horses. He has had invitations to conduct clinics in the USA but we are unable to find out what type of work permit/visa is needed. Clinics would be 3 – 7 days long, a few times a year. He has a diploma in agriculture but no degree, but has been working in this field for 40years. He is an Equine Consultant and teaches/lectures on many areas of the horse industry. What would be the best avenue to look at for this? He would be paid for this work.
