MTR approved without i94

Applied for H4 to H1 in 2016 and petition got denied in NOV 2016. We filed MTR with strong evidences and it got approved in May 2017 without i94.

What are the options available now ? Employer told to wait until Premium Processing resumes so that we can find a new client and apply for amendment as no client will wait in case I apply amendment in regular processing.

Is there any possibility/process which allows me to work before PP resumes ?
