Don't check your passport and visa by plane. Passports and visas are only the identification of passengers when they check in before boarding again, that is, they will be checked when they check in.

Passport is a legal document issued by a country to prove the nationality and identity of its citizens when they enter and leave the country and travel or stay abroad. The word Passport means port pass in English. In other words, a passport is a passport for citizens to pass through international ports in various countries. Therefore, some countries in the world usually issue passes instead of passports.

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 main function of the visa:

Visa is a measure taken by a sovereign country to safeguard its sovereignty, dignity, security and interests. Visa is an important means for a sovereign country to implement entry and exit management. Citizens of a country who want to travel, settle down, do business and study in other countries must have valid passports or travel documents, and another condition is to obtain visas to other countries.

Under normal circumstances, a country issues visas to foreigners on the principle of equality and reciprocity between foreign countries and their nationals, and provides the same preferential treatment and convenience for the nationals of the two countries to interact with each other. However, there are also visa-free countries, such as 18 visa-free countries with China passports and 130 visa-free countries with American passports.

Generally speaking, foreigners are granted different entry visas according to the identity of the applicant and the purpose of entry, such as visas for traveling, visiting relatives, emigrating, studying abroad and working, and the residence time after entry is limited. Due to the different types of visas, the relevant materials needed are also different. Generally, short-term residence applications have fewer restrictions and shorter waiting time for approval.

For the purpose of long-term residence, the application is more restricted and the waiting time is longer. A country has no obligation to allow foreigners to enter unconditionally, and a foreigner has no right to ask a government to allow him to enter. A sovereign country always has restrictions on the entry of foreigners.

With the development of international trade, international political relations and the prosperity of tourism, visa regulations in many countries tend to be simplified. There are also agreements between countries to exempt visas or simplify visa procedures.
