帮忙翻译一下英文，签证要用，急

Question

我们有两个人是同一家企业的，希望能预约同一天的面签时间。但现在的情况是一人预约15日，另一人预约16日（15日名额满了，只能约16日），请问他们可以都15日前来面签么？或者怎样将预约15日的那个人，改成16日？
期待您的回信，谢谢！

Answer 1

We have two people of the same company, hoping to make an appointment be signed in time on the same day. But now the situation is one appointment on the 15th, another appointment on the 16th (the 15th is full of places, only about 16 days), ask them if they can have it on the 15th to be signed? Or how to make an appointment on the 15th of that person, into the 16th?
Look forward to your reply, thank you!
