The Embassy of Belgium in Tunis has given approval to TLScontact, as of September 2, 2019, in order to inform and advise the public on the procedures relating to legalization, to receive the files, to collect the related costs and to return the documents at the end of the procedure.
You only need to make a "visa application" appointment; there is no need to make a "legalization" appointment. On the day of filing, the TLS agent will take your visa application and the documents you need to legalize to complete your application. You just need to check that your documents to be legalized meet the criteria established here .
You will pay all the costs for a visa application and, for the legalization part, you will only pay the legalization costs (20 EUR per document).
