What information do you need to go abroad for the record?

1. 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. 2. Visa refers to the endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to indicate the procedures for allowing them 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. Visas are generally endorsed on passports, and some are endorsed on other travel documents instead of passports. Generally speaking, a visa must be used at the same time as a passport to be valid.
