I've heard from many witnesses to date. When the witnesses are lawyers, they blame the consultants, and when the witnesses are consultants, they blame the lawyers. I don't like this practice.
Here's my personal experience. I have a bachelor's degree in public affairs and international relations. At the end of the three-year degree, I wanted to become an immigration consultant. I didn't necessarily want to become a consultant. I had to choose between completing 500 hours of courses directly related to immigration over a year, and taking courses in private law over a year or a year and a half. However, the curriculum to become a lawyer didn't include any immigration courses.
