RFE - Consultant not responding

USA H1B Visa
1

Hi Experts,

I got an 221g (Blue Slip) from Chennai USCIS. The RFE is on consultant side asking more project documentation.

I need to know -

  1. What is the timelimit for 221g I can submit the documents?

  2. My Consultant is not responding, what are my other alternatives?

Thanks
