How much time is required after IMM Decision Stage ( Dependent VISA)

I submitted dependent pass for my wife and son to Malaysian immigration on 14-Sep-2018. Still the status is "IMM Decision Stage". How long will take to get the approval??

It's lengthier for Indian Nationals as there is also a security check plus a single entry VDR (visa with reference) also needs approval. Allow one month from application to being ready to leave, including minimum 5 days to get the VDR from the Malaysian Consulate in either Mumbai, Chennai or Delhi
