I got H1B visa processed and stamped via Employer A in Nov 2006 in India. I left Employer A and have joined Employer B. Would like to know, is there a way to check the status of my H1B visa. FYI, I have never travelled using H1B visa.

Quick response will be highly appreciated.

You can see name of employer on I 797. Once stamped visa for employer A you don't need to stamp it again for B.
