1、想用英文表達“你是哪國人？”可以說Where are you from，如果想委婉點的可以說成Could you please tell me where you are from?。
2、例句：
Hello. Nice to meet you. Where are you from? 你好！很高興認識你。你從哪裡來？
Miss Wu, where are you from? You look like a southerner.吳小姐，你是哪裡人？你看起來像是南方人。
John this is Loy Chung. Where are you from Loy?約翰,這位是勞埃陳。勞埃,你來自哪裡？
