How to get a Kazakhstan visas?
The Kazakhstan Tourist visa is valid for a single visit of up to 30 days, two visits of up to 30 days each within a 60-day period, or three visits of up to 30 days each within a 90-day period.
Your passport should be valid for a minimum period of three months beyond the expiry date of your visa. Your passport should also have at least 1 blank page for your visa.
When visiting Kazakhstan, no matter if arriving in the country at the airport or at a land border, all visitors must fill in a registration card. This card will then be stamped twice at passport control upon arrival, showing that you’re registered. If you only see one stamp, make sure you ask nicely for the second one.
You must then keep this registration card with you throughout your stay in Kazakhstan. If you don’t have this card with you when you leave the country, you will have to pay a fine or even face deportation.
However, since 10 January 2020, it’s the responsibility of the host or hotel to register travelers. They have to do this within three working days from the date of the guest’s arrival in Kazakhstan and can be done on the Visa and Migration online portal or in writing to the Migration Service.
Travelers who need to obtain a Letter of Invitation (LOI) to visit Kazakhstan, must register with the Migration Police.
