How long is the visa valid?

The validity period of a visa refers to the time period during which the holder is allowed to enter the country from the date of issuance of the visa. After this time period, the visa will be invalid. Generally, countries issue entry visas valid for 3 months, while some countries issue entry visas valid for 1 month. Some countries have strict restrictions on the validity of visas, such as Germany, which only issues visas according to the date of application. The validity of transit visas is generally short.

Visa refers to the procedure of endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to show that they are allowed to enter, exit or transit. 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.
