What's a visa for? Where is the passport?

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.

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.
