Single Status Update
The same problem is being faced by my son. He is likely to get his interview in Oct 2017. The new passport updated as Singh his last name is emailed to NVC on 22 Jul 2017 for correction of name and removal of FNU and still awaiting reply from NVC.
As you have already gone through this dilema of FNU so I want to know from your experience that if it is not updated by NVC before his interview then could it be corrected during Consular Interview?
By the way it will be great if you share your case outcome regarding the same.
Thanks in anticipation.
