I-485 Request for evidence. thanzzzzzz2004-11-30 00:10:36

I just received a letter from NSC to request for addtional evidence. It is asking for a letter from the employer for my current position and wage. Why are they requesting this? Is this a postive sign?

回复：I-485 Request for evidence.

回复：请问，这封信是寄给你本人还是你的律师？谢谢！
