As of December 2019, passport holders of CIS and 48 politically and economically stable states can visit Kazakhstan for a period of 30 calendar days without a visa. If a country is not part of the above list, then it is necessary to obtain a visa to enter the country.

#Photocopy/scan of the passport

#Short application form (we provide)

#Letter of Invitation (LOI) from a licensed tour operator from Kazakhstan

#Accommodation address in Kazakhstan (a hotel as a rule)

It is suggested to check the expiry date of the passport and to contact Kazakhstan Embassy or Consulate for detailed consultation.
