Hello there, we got approved march 18, got the NOA2 hard copy March 23. Rick called NVC March 24 and we already have our MNL case number. NVC also told him that our file arrived @ their office March 21 and will be sent out to USEM soon. Rick will try calling again this Thursday to check if they sent our file to USEM already. I have also emailed NVC yesterday requesting for status update (when it will be sent to Manila) but I used the MNL case number instead of the EAC number already, I'm still waiting for reply though.
I have a friend who was approved March 3, her fiance called USEM last Monday and they were already given options for interview dates (April 22 or May 23), they've settled for a May 23 date. You were approved earlier than them so there is a good chance your case in already @ USEM and ready for interview sched., try verifying with NVC if you haven't done yet and then try calling USEM.
Best of luck to us. GOD SPEED!
