CSC standard procedure and 6-month processing standard
According to the CSC's standard procedure,
the CSC will most likely send the RFE to almost all I-485 applicants when his/her case being picked up,
because the backlog had already reached 15 months.
Even if replying immediately,
it may take another 2-3 months after that.
I wonder if the INS understand the President's backlog initiative that ensures no more than a six-month processing standard for all applications.
That initiative has $500 million budget each year, and we may think that major part of that budget is paid by I-485 EB applicants like us.
