回複：回複：回複：I-485 RFE

Very normal. Most RFE for I-485 is very easy to answer. For examples, I have found more than ten friends of mine got RFE for evidences (i.g. I-20, I-94 cards, OPT, H-1 approval,etc) to prove their lawful presence without gap or verify their employment status. So, don't worry and just wait a few days.
