I've noticed a lot of people asking about why the processing times are looking a little screwy lately. Why are some of the Service Centers missing certain processing times, etc...
I called USCIS and they told me they're updating their computers so the dates may be incorrect or missing until they get everything settled down and all the bugs fixed. To quote the person I spoke to, she said "Even we don't know what's really going on here." mmm.... scary.
But she said they hope to have everything fixed soon.
