Sree, here are the details:
When I submitted 140 and 485, for some reason INS sent back my papers by keeping 140 papers with wrong check(I765 check). When my lawyer enquired they admitted that it is their mistake and they will find the 140 application and let us know.
After 2 weeks INS came back with a response that 140 papers are not found and asked to re-submit the entire case. But by then my labor certificate is lost along with other 140 papers.
I knew that there are so many straight cases hanging around indefinitly and I almost lost hopes. My lawyer re-submitted my case, after 4 months got an RFE asking for financial info. I was expecting RFE asking to get a duplicate labor certiificate. Looks like INS worked on their side and got it from DOL. At last they have approved my case on Sept 13th.
Hope my experience helps someone in future.
Bye.
