In 1998 my ex-employer started labor process and it was approved in 1999. I left the company in 2000 without starting I-140. They had changed their company name in 2001. Recently I got a project work from my ex-client and I asked my ex-employer to re-use of my own labor. They said I cannot use that because it's 2+ years old and company name got changed. Please help me here....it is true???
