Is any fast way to get Approved I-140 copy , if employer is not providing the I-140 copy?

Hi Anil,

One of my friend is facing the issue. Could you guide on this issue?

a) His H1B is expiring on DEC 2020.
b) He is staying in USA more than 6 years using approved I-140.
c) He is planning to transfer his H1B to company B.
d) Is I-140 approved receipt is mandatory for H1B transfer? If answer is yes, Current employer A is not providing the approved I-140 receipt. My friend have one I-140 receipt details. What is the fast way to get an approved I-140 from the current employer ?

Thanks in Advance
