Got 221(g) H1b at mumbai asking for additional documents.

Me(H1b) and my wife(H4) went for our stamping in mumbai and got a 221(g) requestng additional documents. I have submitted all the requested documents.Just wondering how much time will it take to process and also what r the chances we will get our visa. I did my master’s in computers from USA and working in USA. Please let me know I am very confused about the process as there are mixed reviews on the internet. Ill appreciate your feedbak. Thank you.

There is not set processing time. It can take few weeks or several months.
