IMIA promotes unity through the CI Division which stands for Certified Interpreter Division, incorporating CHIs, CMIs as well as those certified by RID, to work together under one roof to further promote certification as essential to professionalization. The IMIA gives complimentary memberships to all who were certified after 2009 as a way to recognize their effort.
