What I would suggest is approaching diplomatic representatives about the validation of skills, diplomas, and degrees.
I know that the government of Canada has accredited doctors who check people's health and safety. I think that a system should be introduced to enable Canada to check people's files more easily. As you know, diplomatic representations are accredited and inject some rigour into the process. They could certainly provide support. If, for example, it became necessary to establish law firms that could verify the documents, it would contribute enormously, and prevent fraud.
As Mr. Sarr just said, there is work to be done at this level.
