Just read a fantastic & harrowing blog post by Dharmesh Shah about getting an ‘Annexure F’ for the Tatkal passport process. Highly recommend you read it & learn from his experience. In short, this is what you need to know (quoted from Dharmesh’s blog):
Annexure F needs to meet following criteria:
A) 2 sets of Originals required
B) Has to be on Printed Stationary and not computer generated letterhead
C) Have to provide ID proof (in 2 copies) as Liquor Card/Canteen Card of the Serving Officer…
(For Public Sector Officials) Need to provide office ID card showing that person’s designation as well. Else, get another letter from the same official stating that he indeed is who he claims to be, i.e He is the GM of Bank of XYZ. etc.
D) The photograph on Appendix I and Appendix F needs to be the SAME one as in the application
