Immigration Voice

I was recently audited by Someone from Dept of Homeland Security regarding my H1-B visa status.He asked several questions regarding my position,job duties,pay,work hrs
How long I was associated with my current company, What was my previous job and job duties,How long I am in US etc.
I couldn't provide him the proof of the pay as I didn't had the pay stub to show him at that moment.

I asked him is this just rutine procedure ?He said this is recently started process...
