I-140 Amendment
Usually, the I-140 amendment is asked by INS as an RFE when they find out that the company that hired the I-485 candidate has been acquired, gone through a name change, or merged with another company. I do not know how that find this out. Perhaps they have access to a companies database. I have also heard that sometimes they may even overlook cases where the original company might have got sold or merged. Some people have got approvals without an RFEs despite company mergers.
The amendment itself is not a fresh I-140. Rather, it is statement submitted by the company to prove successor of interest, or an intention to keep the recruitment of the candidate.
I am in a similar situation. I applied for I-485 in April, but my company merged with another company in July. All my paperwork shows the old company. Though, my parent company still maintains the same federal employer ID, and my pay stubs still show the name of the old company. I am hoping that I wouldn\'t get an RFE for I-140 amendment. My lawyer says that if I do, they will take care of the amendment. I hope that they file the I-140 amendment right away regardless of any future RFEs.
