Sharing Info is always good and it is nice to Share the Info..However my point is Work Site Audit is happening since 2-3 months back and i also had audit 2 months back..As Long as one is Fulfilling  the requirement of  H1b one should be fine..and the info u are supposed to give to the Feds is Voluntary..Always talk to ur Legal PPL before handing any info whatsoever to them..
