Imagine you have landed in Italy and are out and meeting people and exploring your surroundings. After you say “Ciao!” ( the equivalent to ‘Hello’ in English), your Italian friend may become more curious about you and your origins. And if your new friend asks you:
Da dove vieni? 

Don’t be surprised! Your friend just wants to know where you come from. Da dove vieni? (informal) or Da dove viene? (formal), translates to “Where do you
come from?” 

In this case, you should answer with your country of origin. For example:
Vengo dall’Italia (I come from Italy)

You may also hear Di dove sei?, which also means  “Where do you come from?” , with the small difference that Di dove sei? requires a more specific location, and you should answer with the name of your hometown or the most famous city you can think of that can give your Italian friend an idea of the location or environment that you come from.

And you can be sure that there will be many different countries of origin around you. With its historical heritage and panoramic views (not to mention its world-recognized cuisine!), Italy is is a very popular destination for travelers all around the world, attracting over 4 million tourists every year!
