In this case, you must go to the nearest police station in order to declare the loss of the passport. The police will ask you to fill out and sign a form, and then a copy will be given to you. This procedure is very important to remove any liability if these documents are used by anyone for illegal purposes.
A copy of the declaration of loss or theft of the passport must be submitted to the General Directorate of Immigration in Rwanda, which in turn delivers a letter addressed to the Embassy of the State of Qatar in Kigali, which will take the necessary action.
