Everything depends from who you are and what you want to say about you, it does not depend in my view upon the Country. If you write in English or in your native language, maybe somebody will help you translate in Italian.

You can start: Mi chiamo Ahmed. (My name's Ahmed) Ho ... anni. ( I am ... Years old) Vengo da/dal/dalla/dallo ... (I come from + preposition depending on the name of the Country) Sono un ... ( My job is ... literally is "I am a...") these are the basics, but you'll need at least a basic vocabulary about numbers and jobs. Hope this helped you :)
