When you receive the PPR from NDVO, email NDVO/reply the PPR email or write a new email with subject "Urgent! Request for change of passport submission location"
The body of the email can go thus:
Good day Madam/Sir,
Please I'd like to request a change of the VFS for submission of passports from the VFS in India to the VFS in xxxx, zzzz for onward transmission to Canadian Visa office yyyyyy.
I'm currently living in zzzzz and the VFS in xxxxx has refused to accept the passports for submission to the visa office in New Delhi, insisting on a change of location to yyyyy.
I would appreciate an updated passport request letter to reflect a passport submission to yyyyy and not New Delhi.
I appreciate your help.
