How many immigration expert witness disciplines are there?
Our witness taxonomy covers eight disciplines: country condition, persecution, human rights, linguistic identity, internal relocation, CPIN challenge, medical/psychiatric, and oral evidence, each with distinct tribunal methodology.
What is the difference between a country condition and persecution witness?
Country condition witnesses assess conditions on the ground. Persecution witnesses apply Refugee Convention methodology: nexus, well-founded fear, and Convention grounds. Many asylum appeals require both disciplines.
When do I need an oral evidence witness?
