8老师, 我的情况是这样的:
According to Visa Bulletin August 2014, my family I-485 cases are going to be made decision.
Last week I received a letter from USCIS  requesting additional evidence or information in my case (I-485:  LIN1234567890).
And I finished the medical check already and my employer will issue a letter.
Today browse  http://www.uscis.gov, after I input our receipt numbers, I found  all of us are requested to provide additional evidence
[On July 8, 2014, we mailed a notice requesting additional evidence or  information in this case I485 APPLICATION TO REGISTER PERMANENT  RESIDENCE OR TO ADJUST STATUS. ]  , but only I received letter from USCIS, all the other family member did not.
If it is not normal, what should I do?
thanks,
