The difference between visa-free passport and landing visa:

First, it is different in nature: visa-free passport means that you don't need an entry and exit visa, and you can enter the country at the border by showing your passport; Landing visa is a country that has set up visa windows at airports or docks. After arriving at its borders, it can submit relevant materials and apply for a visa on the spot.

second, the operation mode is different: visa-free means that you can stay for a short time without a visa, and landing visa needs a visa to enter the country.
