I filed (self petition) I-360 VAWA (Battered Spouse) with Vermont Service Center on May of 2011. Within a few weeks I received a Notice of Action (797) and a Prima Facie Determination. The PFD was valid for 6 months- twice and in 1 month increments. In June 2012, I was issued a Request for Evidence and I sent additional evidences as required. They received the RFE in August 2012. On USCIS website under My Case Status, it says RFE Initial Review. The same page says that a decision will be made within 60 days of receiving the evidence. It has been over 150 days since they actually received it.
What am I missing here? What could be the case and what would be the solution?
