Standard passports are now issued via the Regional Passport Processing Centre in Hong Kong.
But you still have to apply via the High Commission in Islamabad. You should not send your applications direct to Hong Kong - they will be sent back to you and you will lose the money you spent on the courier charge.
Further detailed information on the application process is available here.
Why have we done this? Please see this leaflet [PDF, 77.0 Kb] for all the changes related to the way we issue passports overseas. If you need to travel urgently and your standard passport is not available we may be able to help you with emergency travel documentation:
Please call the Consular Section of the Embassy and explain that you need to travel urgently.
