What is a visa on arrival?

Landing visa means that the applicant does not directly obtain visas from other countries from the host country, but arrives at the port of that country with a passport and an entry permit issued by the relevant authorities of that country before issuing visas.

Visa refers to the endorsements, seals and attachments on passports or other travel documents held by citizens of a country or region to show that they are allowed to enter or leave their own country (or go to a third country through their country). The visa is usually attached to the passport or other international travel documents held by the applicant. Under special circumstances, valid passports or other international travel documents can be written on a separate sheet.

Some countries began to issue electronic visas and biological visas, which greatly enhanced the anti-counterfeiting function of visas. Visa plays an important role in checking and controlling entry-exit personnel, protecting national security and preventing illegal immigrants and criminals. 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.

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. 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.
