To qualify for an Estonia Schengen visa, the passport must have been issued within the last 10 years and must remain valid for at least 3 months beyond the intended date of departure from the Schengen Area. The passport should also have a minimum of two blank pages available for the visa sticker. Applicants whose passports are close to expiry should renew them before submitting a visa application, as an ineligible passport will result in the application being rejected.
