Arabic fluency -East Africa
It doesn't apply to foreign applicants,that's for the UAE applicants/nationals only who do their applications directly to the headquarters in Dubai...I'm sure of this. The compulsory language is English. Hope I've been of some help.
From the look of things, it seems they do not need East Africans for now.I haven't seen any upcoming AD/OD this year, maybe next year.Keeping our hopes.
