Pakistani National, Residing Bahrain with Permanent Residence permit,Visiting PRC via Hongkong

Adeel, you need to apply for a double-entry transit entry permit for Hong Kong. You can either submit the application to the Chinese embassy in Bahrain or post the application to HK Immigration Department. The application documents include a copy of your passport, a copy of your residence permit in Bahrain, a copy round-trip tickets, invitation letter from a business partner in Shenzhen, and a copy of financial support document. I advise you to get the entry permit for mainland first and then apply for the HK entry permit because a copy of mainland entry permit may be used.

If the embassy deals with your application on its own, it takes four working days to process the application. If your application is sent to HK, it takes four or six weeks.
