What is a visa? Why do you need a visa to go abroad?

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.

1. Passport is the holder's nationality and identity certificate, and visa is the permission certificate of a sovereign country to allow foreign citizens or their own citizens to enter, exit or transit. Visas are generally endorsed on passports, some are endorsed on other travel documents instead of passports, and some are issued separately.

2. If a citizen of a country wants to travel, settle down, do business or study in other countries, he must have a valid passport or travel document, and another condition is to obtain a visa to other countries.

3. There are three ways for China citizens to apply for foreign visas:

(1) I apply directly to foreign embassies and consulates in China;

(2) Entrust the visa office of China Travel Agency (generally limited to tourist visas);

(3) Foreign relatives and friends directly apply for a visa to the country's immigration bureau.

4. The validity period of a visa refers to the period during which the holder is allowed to enter the country from the date of issuance of the visa. After this 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.
