Can I use a long-term single-entry visitors visa to look for work in Dubai?
I have googled for clarification of what activities are covered by a long-term visa without success. The signs are that Dubai may not care much what 'type' of activity one gets up to once allowed into the country. I have a suspicion, whether or not strictly illegal, they will be happy to turn a 'blind eye' almost all the time – but might come down with draconian repercussions at any moment that suited, whether or not 'strictly' legal. In effect, the law is what happens to be convenient at the time.
However there is precedent from other countries where job hunting is considered covered by "tourism", so there is no real risk in my opinion. And there is evidence that others have looked for jobs while in the country as a 'Tourist', for example a post by Fida Karim from Jan 28, 2015 opens with:
Most of us, if not all go to the UAE on a visit or tourist visa for Job Hunting!
For anybody thinking of job hunting in Dubai on this basis I suggest that whole post is worth reading.
