485pending，还收到RFE，已经递交了相关文件，等待期间可以换工作吗？
-Yes.
新雇主说可以马上拿到新的H1B，不用等再次抽签，换工作会不会影响绿卡申请？
-If your I-485 has been pending >180 days and yur new job will be in the same/similar field as the old job, then it will not affect I-485.
如果没问题的话，到新雇主那里需要带什么文件可以继续等绿卡批下来？
-Do nothing now. If USCIS send you RFE for employment status, just ask the new employer to give you an employment verification letter.
谢谢。
