RFE Notice...but still didnt receive them

I received Email that USCIS need more information about my file on Dec 22

but i still didnt receive any of mail from USCIS....

Should i call USCIS on monday?

My Lawyer Didnt receive them either.

Wait one more week before calling. Did they say they already mail the RFE? Is there a tracking number to track with?

Dude same here. I checked my case status online and it's says. "On December 21, we mailed a notice requesting more evidence/information for this case" but I still haven't received anything thru mail. I called, and the lady made a report and gave me a reference number. She said to wait for a call or an email. What the hell is happening. Why me? I've been waiting since August.

You guys might want to call up USCIS just to see if it wasn't a glitch in the notifications. Remember that RFE have deadlines so it might be best to make sure you get the notice ASAP if your supposed to get one.
