I have a pending GC ( EB2 category ) , have approved i140/EAD/AP but still using the H1B (5th year) . Priority date June 2007. Employer is based in chicago and LCA was filed for chicago. But I have been always working in CA.Only in 2009 I asked the empoyer on why he didnt have a LCA for CA after which he filed a LCA for CA. My question is if i get a RFE/NOID saying that when my 1485 was filed my H1B LCA was still for chicago ,how can i address that RFE ? I was not aware fo the LCA rules until 2009 when uscis issued memos, pls let me know what i need to do to defend if i get a rfe/noid on this (seems like couple of people are getting it already).I travelled out and came back in 2009(CA) with a valid h1b as well. How can i be responsible for the employers mistake?how can i be prepared for ?
