Hello,
I would like you give you some informations regarding this,
I was trying since 2 weeks for getting this police certificate, I'm living abroad and exectly as you, i need for my visa office too. As i had experience, no one can get certificate on your behalf, some one can get certificate but most common certificates that police issue are for travelling out from pakistan, like one person is going to travel and he needed or some one wanna submit inside of pakistan to any embassy or etc. I called direct DPO ( District Police Officer ) first they were not ready to accept, they told me i must come through pakistani embassy, they issue police certificate for pakistani living abraod only via Pakistani embassies, when i told them where im living there isnt any Pakistani embassy, so what i supose to do.... then they replied mi, fax them my passport copy and national id copy notarized from my country's notary, included one application for what i wanna take this and then 2 pictures by mail. This is all the darama, now just today evening i sent documents by fax to their given numbers, it cost me $35 and when finished, it returned with errors, the fax guy told me he is not sure if all document delivered successfuly. Now this all i gonna write in one letter and submit to embassy, dont know what will happen but getting Police Certificate from Pakistan is really Frustrating. I called Pakistani embassy Los Angeles, as they issue all kind of certificates to pakistanies, they told me it will take around one and half month to get Police certificate and still they are not sure too.
This is all my fresh story. Please write down if any body have got police certificate from pakistan using any method. This will help us all.
