Humaid Bin Deemas, assistant undersecretary at the labour ministry, said there are around 250,000 illegal workers whose whereabouts are unknown. "The workers have either expired labour cards or they have failed to get a labour card after they have been granted a permit."

250,000 illegals. That's a lot relative to the number of citizens which is around 1,000,000 or the number of ex pats which is around 4,000,000.
