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?
When the tribunal may direct cross-examination of expert evidence, or where methodology and findings are disputed. Instruct witnesses prepared for FTT or UT oral attendance from the outset.
