[raj_kool5566]

in sep 29 2010 applied for h1-b 7th years extension,vendor location as client location but working in client location . h1 approved on mar 15 2011. USCIS officer visited at vendor location on MAY 20 2011 for verification and i was not there. received NOIR on APR 2014 for previous h1 2010 - 2013.
1- does it effect my GC process, as my PD date EB2 APR 2009 ? from oct 2013 i am using ead/AP with same employer and no h1 applied.
2- if my previous h1 revoked ? will i be in out of status ?
3- how to proceed if revoked , do i need to apply for new h1 or can work on EAD/AP
4 - After h1b - expired , why uscis officer sent NOIR for expired h1-b ? after 3 years
