What is the difference between a passport and a green card?

1, a green card refers to a permanent resident, that is, a person who can stay permanently in China but is not a citizen. Passport means that you must have a passport if you want to travel or study abroad.

2. 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.

Green card is a permanent residence permit for foreign citizens. Holding a green card means that the cardholder has the permanent residence in the issuing country, and at the same time, holding a green card can exempt entry visas for a certain period of time.
