Status of Issued H1B Visa after resignation from sponsor

USA H1B Visa
1

Hello Team,

I have H1B stamped visa. Stamping happened in Sept 2014.

I have resigned from the sponsor company and have never traveled to USA .

Where can i check if the VISA has been revoked by past employer or what is the current status of my VISA.

Thanks in advance.

Although current status is invalid because you don’t work there.
