Question: Is it real to pay for job recruiment prcessing fee in job in dubai?

Never, ever give someone else money for hiring you. If they want you, here’s the rule, they pay you (not the other way around).

Answer:

No. Recruiters (or "headhunters") work on the basis that they receive payment from the company that ends up hiring you. It's usually a % of your salary.

You should not be paying them yourself. If you are being asked to, it sounds likely it is a scam.
