When UAE noticed violence of some ignorant Nigerians and other nationals, they quickly halt "Nigerian Visa" they noticed that there are many Nigerians in UAE, they held an inner caucus meeting to deport anything Nigerian in UAE, first they examine  you, if they value your contribution and asset worth they leave you, if you're worth a significant they leave you because they know that someone whose worth some fortune drops tax and would rarely cause trouble especially petty cultism and poor hangout groups discussing how to make quick money, RN Nigerians in UAE are on "Watchlist" after all you don't have the best of "engineers" you don't have the best of "Craftsman" so what's my interest in accomdating you? That's how an average UAE Leader thinks...so reading through the list you'll find out that whatever the dude mentioned here they achieved it all...is that how a nation is supposed to run? To me..to an extent. and to you stop traveling to discomfort your hosts with your corrupt and violence lifestyle.
