This internship report is a small summary of the import and export procedure in the banking system (International Union of Banks as example). In this work, I tried to shed light on the regulations of the International Union of Banks regarding import and export transactions. The point of this internship is to make business students understand the process of a customer’s request for a bank acceptance of import and export documents. Customers can be familiar with the procedures and needed documents. Also, they can be aware of how to send documents and the best delivery and payment modes to use. Это и многое другое вы найдете в книге The International Procedures in the Tunisian Banking System (Sabrine Messaoudi and Borni Lafi)
