An exit visa is a document that grants permission to leave a specific country. However, some countries use other terms to refer to this type of document. For example, in Russia, an exit visa is called a выездная виза (vyiezdnaya viza), while in Saudi Arabia, it's known as خروج (kharooj). In China, the exit visa is referred to as 出境签证 (chūjìng qiānzheng), and in Cuba, it's known as an autorización de salida del país. Regardless of the term used, the purpose of an exit visa remains the same, which is to control the movement of citizens and foreigners leaving a country.
