Can you tell me again? Where's the passport? And where can I get a visa?

Passport is a proof of your nationality, and it usually needs to be handled at the Exit-Entry Administration Office of the Public Security Bureau where the household registration is located.

Visa is the annotation and seal of the sovereign organ of a country on the passport or other travel documents held by its own or foreign citizens to show that they are allowed to enter or leave the country or pass through it. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country's entry-exit administration (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens. Generally, it needs to be handled at the embassy of the destination country in China.
