If I am correct, no, and I don't think it's called "licensing". All exams are done in Qatar (I think in HR), like all other processes applicants of HMC have to go through, and it' all just for qualification to HMC, not to have a "license" in HMC 'cause I don't think there's such a thing, although I could be wrong. But I'm almost sure my aunt didn't have to take an exam while she was still here. She simply passed her requirements to HMC I think through my dad, then months after she got hired, she finally flew to Qatar.
