Got passport request for Mom.. But no reply from NDVO about Dad's request for reconsideration of the TRV refusal.Okay. In that case, NDVO is the correct visa office to communicate with.
Do not reapply for your dad.... not yet. You must send another email and webform to NDVO to request for reconsideration of the TRV refusal. VFS made a mistake that resulted in your dad getting refused. Reconsideration is not the same as a new application.
Her application will continue to be processed independently
