221(g) blue slip

Hello Anil

I came to india for my H1-B stamping and I have received 221(g) blue slip today from NewDelhi consulate to provide some additional documents

A) client letter, contracts, MSA between vendor and client.
B) itinerary of services, with project details, budget, employees at location etc
C) Petitioner’s Tax Returns
D) List of Petitioners employees

I have provided all requested documents but my case status hasn’t changed yet, can you guess the timelines for consulate to respond and what are chances of approval for this case.

Thank You
