I hope this is the correct area?

Please could anyone confirm this for me. I require the following for a visa extension:-

'A letter of confirmation from the Department of Labour that at least 60% of the total staff complement employed in the operations of the business are citizens or permanent residents employed permanently in various positions'.

I have been informed that this is covered within a Letter of Good Standing from the Compensation Fund. This would make sense to me, as you need an employee in place to pay the CF. However, if my information is incorrect, would anyone know how I would obtain such confirmation from the Department of Labour? Proof of contributions to the CF is also required separately.

I also have proof of contributions to the UIF (up until the new system stopped working), so surely this would also help with these requirements?

Could anyone assist? Any help gratefully received! Thanks.
