I-140 NIW TSC date going back


Registered Users (C)
About a month ago I-140 NIW current date was 07/18/2002. Now it is 06/26/2002. Do you guys have any idea why it is going back!

Also I checked my status online. Again about a week ago it was saying that it will take 175 to 200 days. Now it is saying 275-300 days. Whats going on. Is that normal.
