ICT, Critical Skill and Dependent Visa in South Africa?

Hi, I am an Indian Citizen, working for an MNC for last 8 years. I have got an opportunity of transfer to South Africa branch of the same company. If my company applies for ICT, I think my wife (also an Indian citizen) cannot work in SA - Am I correct in this? If so is there any provision or type of WP (like Critical skill - I am an comp sc. engineer with 10+ years exp), which I can apply which will allow my wife also to work in SA. She is an electronics and telecom engineer, working on software industry for last 6+ years. If there are no such provisions - then what can I do to ensure that my wife gets to work in SA? Thanks for all your replies in advance. Regards, Dipankar
