it seems it will take 90 days depends on case.
I think ,
if it is motion to reconsider it may take less time,
motion to reopen may take more time as they have to verify new documents,
appeal may take 180 days as it will go to AAO office.
But I am not sure how this will work , i just got this information from other blogs.
in my case it is motion to reconsider. what about yours?
Today I got new receipt number but it does not shows my name and old receipt number.
I got denial notice on 25th-jan-18 from that time 30 days’ time is 24th -feb-18.
But my attorney submitted on 15th -feb-18 before deadline.
But my receipt date shows 2nd-mar-18. I am not sure why there is miss match, what I heard from attorney is USCIS is delaying sending receipt numbers.
now my concern : is this notice is mine ore not :).
can you provide more details about your case?
