请问"您居留许可证的有效期到什么时候"怎么翻译？

您居留许可证的有效期到什么时候？
When does your residence permit expire?

可不可以语气委婉一些？
Would you mind telling when does your residence permit expire?

What is the expiry date of your entry (resident) permit ?
改为
Can you kindly please tell me the expiry date of your entry (residence) permit ?

Could I know when will your residence permit expire?

May I know the expiry date of your resident permit?

楼上的,Would you mind telling when does your residence permit expire?
你的does是多余的吧.

应该是 Would you mind telling me when your residence permit expire?
或者
Would your minde telling me the the expiry date of your resident permit?

楼主你自己斟酌吧?意思已经很好了,不用担心对方觉得你粗鲁.

What is the deadline of your residence permit?
What is the expiry date of your residence permit?
When does/will your residence permit expire?

等等表达都是可以的。

语气委婉一些？请问您给出的中文原文的语气委婉吗？英文翻译出来的语气和中文差不多的，都是很正规的说法，没有什么感情色彩。
