How many times does it take for a returned student to get a visa?

International students can return to China reasonably by applying for a visa before returning to China.

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 its own territory 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 department (such as immigration bureau or its embassy or consulate abroad) to express approval to foreign citizens. The visa is usually attached to the passport or other international travel documents held by the applicant. Under special circumstances, valid passports or other international travel documents can be written on a separate sheet. One-stop study abroad strategy in ing.com
