1、想用英文表达“你是哪国人?”可以说Where are you from,如果想委婉点的可以说成Could you please tell me where you are from?。
2、例句:
Hello. Nice to meet you. Where are you from? 你好!很高兴认识你。你从哪里来?
Miss Wu, where are you from? You look like a southerner.吴小姐,你是哪里人?你看起来像是南方人。
John this is Loy Chung. Where are you from Loy?约翰,这位是劳埃陈。劳埃,你来自哪里?
