H1b amendments for in-house project with same employer

Hi Anil ,

I have h1b visa with client A (client location saint Louis )and employer A (state is CA) and I have valid stamped visa till dec 22 and last month my project ended with Client A … and I got in-house project with same employer … do I need to go amendment as I am planning to India

I think an amendment would be required here.

I requested my employer … he is saying there is no need … really I am confused
