Hi

Currently i work for company A and i transfered my H1B petition to another company B. Transfer is complete but i didn’t resign company A. Strangely last week my current employer asked me to come back to India and he told me that he is aware of my H1B transfer. Is there any way that USCIS will notify my current employer if transfer is complete?

No. uscis will not notify your old employer regarding your transfer

Thanks
