I applied for my H1B to H4 COS in Dec 2010. My wife has a valid H1B till 2012. However, my COS was denied without any RFE. I got a letter from USCIS that they asked for an RFE which was supposed to be replied back by Feb 2011. Since I have not responded back, they are abandoning my case and denied my COS.However, I never got any correspondence from USCIS regarding RFE. I was regularly tracking USCIS website for my case update and even there was no mention of any RFE.
I have few questions regarding my case and would really appreciate any help.
1. Should I file for Motion to reopen and then go back to my home country to get stamped or I can just go back, get it stamped without filing Motion to reopen.
2. Can I call USCIS and ask for their reason for denial.
3. What are the options left for me now?
