This is not question but one information i would like to share with all.
30% application still showing case recieved Status
USCIS declared 3.5 to 7.5 months cut off time atleast for california centre. That makes Dec 31st as cut off.
3 Do not contact USCIS before that as any direct call can trigger system update on your case and officer would think that some thing has been done on this case, he can put your case behind in queue.
