my wife has an excellent job here in the US (she's a microbiologist). Can women easily find specialized work in Dubai?
I'm no expert, but generally the Middle Eastern countries welcome specialists with open arms. Two areas where there seem to be a general lack of personnel are medicine and schools (teachers). She should use whatever channels she has to check out different options, maybe a trip to DXB to knock on some doors before you decide to move? It will give you both a chance to check out DXB as well.
