Hello, I have the same problem as yours. My NOA1:December 13th, I received an notification 8th Feb about RFIE. and yesterday I recived a letter as same as yours. If you do not mind can we be in the contact on Facebook or somewhere? We called at USCIS on the very same day when we received the letter mentionening I-130 which we did not applied for. The agent who picked up the call told me that someone will contact me within next 30 days!!! It is not acceptable, while it is their mistake!!!
