How do I issue my wifes final exit visa correctly?

Greetings:

My employer has told me that I must issue my wifes final exit visa myself. He will issue my final exit visa (he is my kafil), but I am her kafil so I must issue my wifes final exit visa myself. I am very nervous about this. This is our first time leaving Saudi Arabia so I dont want to make any mistakes. Does anyone know the exact steps for this? My real concern is the number of days we will get between receiving the final exit visa and actually leaving Saudi Arabia. My employer tells me that because my iqama ends next years, the Ministry of Interiors system will probably give me 60 days to leave Saudi Arabia after I receive my final exit visa. However, is this true? Will I receive the 60 days or will I receive whatever time my employer wants to gives me, like three weeks or even three days? Assuming however that I will receive 60 days to complete my final exit after I receive my final exit visa, how can I make sure that my wife receives the same 60 days when I issue her myself her final exit visa from Saudi Arabia? It would be a big problem for me if I get 60 days to leave Saudi Arabia, but I very unfortunately only gave my wife 6 days.

Any advice or information anyone can give me in this matter would be greatly appreciated.
