I am in H1B. Working for Company A They filed my GC in EB3. Labor approved in Nov 2008 and I140 Approved March 2009. H1B will expire (2nd Term) in Sep 2013. Company A wants to apply for extension not interested in EB2 Conversion. I am a lead and recently got promoted. Company B is willing to sponsor GC & transfer H1B. My question is if I join B whether my priority date will stay and can be used for EB2 filing? I am from Nepal.
