Saudi Arabia Labor law

Dear Sir,
My name is Khaja Nizamuddin and I'm working as Process Engineer in Bharat Oman Refineries Ltd, which is located in Bhopal, India. I want to move to Saudi Arabia in future in companies like ARAMCO. My wife is practicing Doctor in India. If I get a offer from any of the companies from Saudi Arabia & get a family visa status, does my wife can work as Doctor on my visa. What does the labor law says regarding jobs for spouses of expats.

Request you to kindly clarify my doubt.

As per Saudi Labor Law, dependant expats may work now in only health and education sectors, and not anyother. But, they need to get registered to ministry's "Ajeer" Program.
