I am new user when I am creating account on fiverr by default my country set Italy
How can I change
You cannot, neither the Fiverr CS.
The system detects it automatically. If you continue browsing from a location for more than 60days or so, the system will auto-change your location.
You can only select your country during when you created an Account.
I see, then all I need to do is use a VPN for two months! helpful information
