Yes, children may need to pay a visa fee depending on their age. Children between 6 and 12 years old must pay a reduced visa fee of €45 when applying for a Poland Schengen visa. However, children under 6 years of age do not need to pay the visa fee, as they are exempt from it. Even though the fee may be reduced or free, children must still submit a visa application and provide the required documents when traveling with their parents or guardians.
