The cost of a Finland student visa is approximately €350. This fee must be paid at the time of submitting your application and is non-refundable, even if your application is rejected. Additional costs may include biometric fees and medical certificates if required. Be aware that you may also need to pay for language proficiency tests or any other supporting documents needed for the application. It’s recommended to confirm all costs with the Finnish consulate in your country, as fees can sometimes change based on the country of application.
