I got my I140 approved under eb2 in 2008 from company A. After that I left that comapny and Joined in Company B. My I485 was filed in 2013 with Company A's I 140.that means I was not with company A when I filed my I485. Currently I am working with Company B. But Company A is asking me to join in their company. it is been more than 180days that I filed my 485. is there any risk if do not go back to comnapy A and continue with company B? will there be any RFE on this issue ?
