For instance, when it comes to architects who arrive in Canada with a significant amount of experience under their belt, the obstacle has more to do with the obligation to obtain a licence in order to be recognized as an architect. That process is seen as an expensive one, even more so than in the case of lawyers, for instance, who open a practice.
Actually, the status of foreign architects who find a job in an architectural firm is inferior to that of an architect. They find themselves lacking the motivation to advance in order to go through the steps leading to the official recognition as architects and the acquisition of all the authority related to that status. That's the main obstacle.
