The Kazakhstan Treatment eVisa is designed for eligible foreign nationals traveling to Kazakhstan for medical treatment. The medical-treatment visa is classified as category C12 within Kazakhstan's visa framework. Government information states that electronic medical-treatment visas can be issued to eligible citizens based on the required invitation or visa support from the Kazakhstan side. Earlier official guidance describes the C12 eVisa as a single-entry visa with validity of up to 180 days and a permitted stay of up to 90 days. Applicants should provide accurate passport information and any medical or supporting documents requested during the application process. Travelers should confirm their eligibility and current requirements through Kazakhstan's official Visa and Migration Portal before applying, as visa categories, eligible nationalities, fees, and procedures can be updated.
