When should the deposit collected by the overseas tourist embassy be returned after returning to China?

The purpose of applying for a visa and collecting a deposit is to prevent "smuggling" and never coming back. After you come back, it will be returned to the individual in a week or so.

When traveling abroad, only getting a visa will involve the issue of deposit. According to the country you are going to (some countries don't need it) and the quality of visa information, more or less deposit will be charged. For example, when applying for a visa, the deposit will be higher, up to 15, or more. If the visa information is complete, the deposit will be less, about 1 thousand.

brief introduction of visa: a visa is an endorsement and seal on the passport or other travel documents held by domestic or foreign citizens by the sovereign authorities of a country to show the procedures for allowing them to enter or leave the country or pass through the country. 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 management agency (such as the Immigration Bureau or its embassies and consulates abroad) to express approval for foreign citizens to enter the country.
