Remind me, have you recently contacted KCC to find out if your case file has been requested by your FO and sent out to them accordingly? Even though you've been able to confirm your lawyer didn't fill out the DS form on your behalf, I'm certain it's not the reason your case is yet to be approved. I wouldn't recommend you fill and submit the form now since you've already had your interview, may end up causing more harm than good. What you're currently experiencing is not unusual, even for a DV case unfortunately. Plus the NYC FO is seriously backlogged, just like
@ndubs just confirmed above. I would suggest you schedule an infopass on your own and pay the FO a visit, stop relying on your lawyer (yeah, I know you paid him/her(?) thousands of dollars
).
