I601a waiver question approved after death

[Raj shresta 0]

Brother sister petition was filed and the visa is current
Sister is in the America to waive the 10 year bar we filed the i601a waiver through mother 
>>>days before the waiver was approved the mother passed away <<<<<
Since the waiver is approved the next step is NVC. 
Does the waiver still stand or is it invalid since the person passed away couple of days before it was approved
Can INA 204(L) help save my case if its invalid...

  There is no qualifying relative anymore.  It was approved in error because they didn't know she was dead.

You are correct. I thought you can still go to interview but cannot.... Talked to different lawyers only thing you can do in this case is 204(L) if it applies...
