Oh intergate Immigration cn only help if u hav job there already.. They are like any other company who does Visa processing.. I was in contact with them too.. Initially they showed as they gonna do VISA very easily.. but later on nothing was done.....

They may tell you that.. For VISA you need job offer and othyer documnet.. By the time u get job they will do ur other documents...
And then they gonna charge you for other documents...

And Finally you will find that you have paid them for processing other documents, but still donthave job.

The biggest problem in getting job is, Employer needs to run Ad on news paper... And that u need to attach with your VISA application, And Employers have to state that they were not able to find and resource or people who applied for the job were not upto he mark...
FOr that Ad only they need to pay around 100K+ ZAR....

Thast wh no emplyer goes for this option.. instead they take people from companies.. who bring people in SA in Intra Company Transfer Visa....

Thast all i know abt VISA thing in SA....

Hope it helps you and warns you not to pay for anything till you have job offer and proof of Ad in your hand.

Cheers
Anu
