As soon as your application is received, you receive an immediate confirmation with the reference number that your application is assigned. After that your application goes through a verification process… The process takes 5 business days (excluding Saturday, Sunday and National Holidays). Once approved, applicants will receive their Visa Approval letter by email. Print it out, and take it with you to the airport. You need to show the Visa Approval letter TWICE: To the airlines in your country when you check in and to the Immigration officer at the São Tomé airport upon arrival to get the visa stamped onto your passport. You are then required to fill out the entry and exit form, and pay the visa stamping fee (see the visa stamping fee) to directly the Immigration officer.
