Hi Depak,

if it is ICT visa, then i m afraid, u can not change company with that VISA. U'll have to go back to ur home country and apply for workpermit( temporary residence Visa) On this visa only u can work... Else u have other option.

if you have 5 years of exp in current field of expertise and your skill comes under rare skills as listed by SA immigration authorities. u can apply for visa , go to SA and look for a job, though u get only 3 months to find a job and get it transfered in the name of ur new employer.

I to got a visa which is vlaid till next year, but that was filed by my ex employer.

best of luck, I'll get back to you on staffing company ID soon.

Cheers
A
