Ask HR to contact USCIS.
I am not sure how long it will take to get the approval notice. If I file 485 using the receipt notice, what will happen?
-No difference from using approval notice,
RFE finally? So I still need to get the approval notice anyway, right?
-No.
Will USCIS give me EAD and AP if I use receipt notice to file?
-EAD/AP application is only related to your I-485 filing, not I-140.
I appreciate your replies.
