Like I'm from France and if you grew up in France, but you don't live there, now, you might say I'm originally from France also, if you're talking about which country you're from, you could just say your nationality such as I'm French.
比如我來自法國,如果你在法國長大,但現在不住在那裡,你也可以說我來自法國,如果你說的是你來自哪個國家,你可以直接說你的國籍,比如我是法國人。
