I received my new passport today. Quicker than expected.
Applied last monday (18/11/2019)
Recevied text yesterday, that my application is processed succesfuly and new passport dispatched
Recevied my new passport today. So, in just 8 working days, I received new passport.
Regarding PFF, when I was applying, I Spoke multiple times with vfs customer service, just to be very sure if PFF is manditory and each time they said PFF is manditory. I mentioned to them that my friends who applied 6 months ago, did not provide PFF, but they said the rule has changed now and PFF is manditory. I went to the VFS without filling the PFF, but near the counter the lady gave me the form and said I must fill PFF, even though there is no change in address, even though nothing has changed from my old passport.
So guys, thats my experience. So its up to you to fill PFF before going to VFS or fill it near the counter whilst submitting the application.
All the very best, I did not get answer for my query on time, hopefully this will be little help for those who are confused whether PFF is manditory or not.
