Can I get visit visa for Beijing ?

Well, Faisal, I'm not sure whether you can apply by yourself. Maybe you will be required to apply through a travel agency because the invitation letter from China Tourism Bureau may be needed. You cancontact the CVASC office or Chinese embassy to confirm this. In addition to this letter, you need to prepare your passport, a copy of your passport, the original and photocopy of your residence permit in Italy, application form, bare-headed photo, and round-trip tickets and hotel bookings. As you are Pakistani citizen, you don't need to pay for the paperwork itself, you may only need to pay the service fee of the CVASC, which is €67.10 for regular service.
