WASEEM from Pakistan want to visit HK

You cannot use the X2 type to enter HK, so you need to apply for another entry permit to go there. The required documents include copy of your passport, hotel reservation, application form, a passport-sized color photo, flight itinerary, proof of your financial standing and your travel plan. After, submit the application to Beijing Office of HK SAR government to apply for it.

Besides, if the X2 type only has single entry, so if you exit mainland PRC, when you want to re-enter, you need to re-apply for a new X2 type.
