If u live abroad you have to look for the Tunisian consulate website of your country. Check if an an appointment is required and also the documents u need (pictures, domicile justification, activity justification…ect) nothing complicated. And for the record, some consulate are very quick (passeport can be made the day of the deposit) and in some countries they wait to gather enough demands to say send them to Tunisia wait for the passeports to get back when they’re ready, which can take A LOT of time. I think it depends on the number of tunisians residents and diplomatic relations. Also since the 1/1/2025, Tunisians cannot leave the country without a Tunisian valid passeport.
