Can the employer make the employee pay visa charges for resigning during probation?

I have a Bike Delivery Service Company. I hired a non-skilled bike delivery rider and did all his visa process. When that employee came to the UAE, he changed his mind.

He wants me to cancel his visa and give him his passport back. I have already gone through all his process of visa, labor card, and medical test booking.

Is he liable to pay me for all of this or am I just supposed to cancel his visa without asking for any compensation?
