H1B, H4 Visa

Hi. Myself and my husband got his H1b picked and approved in the year 2015. We came to India this year April for stamping(our wedding was fixed). I got my H1b stamped BUT my husband got 221(g) pink slip. He works for American company. While filing for his h1 in 2015 he filed two(so did I), one with his current employer and the other through consultancy, both got picked and approved. In the visa interview, interviewer asked more about 2nd H1b and why didn't you take up that? why did you plan? What is the package for that that? Where is the job location?
On may 5th uscis sent an email to 2nd consultancy employer requesting for documentation so both his current employer and 2nd h1b employer sent uscis documentation. From April 4th(his interview date) till now whenever we track on ceac.state.gov it is showing the status as "your search didn't return any data". Is there any way we can check the correct status? I am very worried since even though they requested information nothing is being updated AND also not sure till when we have to wait. I have booked our flight ticket for this may28th. Please help me with any of your suggestions. Thank you so much for your help in advance.
