The standard fee for a Belgium short-stay Schengen Visa is €90 for adults and €45 for children aged 6 to 11 years. Children under 6 years old are exempt from paying a visa fee. These charges are non-refundable, even if the application is refused. Additional costs may include service fees charged by the visa application centre, along with expenses for travel insurance, medical certificates, and supporting documentation. Applicants should also budget for courier services or optional premium services if they choose them. Always ensure fees are paid through approved channels to avoid delays in processing your application.
