H1-B Transfer - No reciept - PP

Hello Experts,

My attorney filed my H1B transfer on April 17th, I have the Fedex receipt that it was delivered on April 17th. This is a standard H1B transfer. I pinged my attorney several times and he does not give me the receipt number or any details. Just does not respond.

This is filed under Premium Processing and it has been almost 2 weeks! What is the delay these days for receipt allocation for PP? I have no information from my lawyer or employer and getting a little concerned. I tried finding the LCA and could not find that either.

Any way to find the details as 15 calendar days are over and I am not sure where my H1B transfer is! Please help.
