I know of people working that don't have a degree, but I think that is not the norm, as degree certificates (attested) normally form part of your application for Qatar Id (for management position) Is that the case with your own job and application? The one possible plus on your side is that you have a job and therefore he will be coming under your wing so to speak. In terms of construction management jobs, then try the Gulf Talent website. What sectors has the 20 years been spent on, as I could possibly point your in a particular direction?
