-If you receive RFE for employment status again, you need to ask Company C (your current employer) to provide the employment letter. As long as Company A does not cancel the I-140 or your I-485 pending>, and your work is the same/similar field, your I-485 should hav eno problem.
今年年初時,收到RFE,也交上去了,不是雇主信,再收到RFE的可能性大嗎?
-May be yes,or may be not, depends.
