After you file

Hi I am in a similar situation ITIN rejected so we have to send supporting documents related to the tax and a new W7 together with the notice to the address on the top witch is the same PO Box and address for the ITIN CENTER 
So my question is :

How long is going to take now???  
since we already have a case number do you think they will process this faster?  🙏

Please any answer Thank you
