S Pass update salary for applying DP

Since I raised salary more than 6000 sgd, now I can apply DP for my wife, but MOM let me update salary on MOM 1st, they let me supply payslip reflected as the new salary for 3 months, but I just raised salary since Feb, HR explained to them as I find that it does not make sense to wait for 3 months, now this is still subject to approval, may I know what is the chance of passing, and how long you usually waiting for the approval.

Thanks for answering

If MoM's requirement is three months of payslips with the higher salary, then you probably have to wait for those three months. They are making the rules here!
