Can you provide a link to where this information is?
Clio - I missed your question before - sorry.
If you go to the USCIS website to check your case status, enter your receipt number and it gives you YOUR case status. If you scroll to the bottom of that page, there are drop-down boxes to select the form type and district office and it will give you stats as of, I believe, July 30th. It shows national goal, national average and the average of your selected DO. Right now the national average is 5.1 months. Goal is 5 months. My DO is still showing as 5 months but lots of people on the trackers are taking longer than that. A few take less - I guess somehow they come out with an "average" of 5 months.
Athena - somebody on another forum I visit, also had their time frame change to 90 days. Maybe it's something they did across the board? Probably getting too many calls LOL!
