Travelling with amendment receipt number only

I am currently in India. I have my visa stamped with client A. I need to travel ASAP to client B from India. Is having only the amendment application receipt number sufficient to be eligible to travel or I need to wait till it gets approved and have the new petition copy in hand? I have heard it takes around 90 plus days but that’s too long to wait for the requirement. Kindly suggest of options.

Hi, when did u applied for amendment, how long it will take to receive amendment receipt notice…

Ask client B to do premium processing which takes 15 days. However, premium processing is currently stopped until end of August.
