Getting visas to Kazakhstan
The Republic of Kazakhstan and a significant number of States have concluded international agreements on visa-free travel. This means that citizens of these states have the right to enter the territory of the Republic of Kazakhstan without a visa. But this regime assumes a limited amount of time during which citizens of these states can stay on the territory of Kazakhstan, as well as, very importantly, restrictions on goals, usually only tourism. That is, the visa-free regime, as a rule, allows you to stay without a visa on the territory of Kazakhstan for the purpose of tourism, but does not give grounds for work, study, etc.For purposes other than tourism (work, business purposes, etc.), as well as in order to increase the duration of continuous stay in the territory of the Republic of Kazakhstan, it is necessary to obtain an appropriate visa.
So there is a special type of visa for each purpose. For example, a C3 visa is for work purposes, a C5 visa is an investor visa, etc.
