I just went back from renewing my passport at Port Klang office.

8.15 : Arrive there & submit completed form,IC & photos, got numbers & few second later my number is up (Suprising that I dun need to Q at all..hahaha)
8.50 : Payment
10.50 : Submit receipt for passport collection
11.30 : Received my new passport

Perhaps the time taken for my number to be called for collection is a bit too long? But overall, I'm satisfies coz everythings was done around 3hrs only.

kca : I submit my photos which is 4.0cm x 5.0 cm,(which actually taken almost 3 years ago!Guess my face is still the same..yay!)and confirmed with the officer there, no problem at all.
