Quote from my attorney's email, "Even if we file a Writ of Mandamus the case cannot be approved because of retrogression. After retrogression, if she's still interested we can look into a WoM." I think I will wait until visa number becomes availbe to file a Wom. In the meantime, I will collect evidence such as letters to congressman, senator, inquiry to uscis, and first lady. Good luck you all!
