Questions & Answers about qǐng zài chuāngkǒu tíjiāo shēnqǐngcáiliào.

What does 请 mean here? Is it just please?

Yes, in this sentence 请 is being used as a polite marker, like please in English.

So 请在窗口提交申请材料 means something like:

• Please submit your application materials at the window/counter.

In Mandarin, 请 often appears in polite instructions, requests, and signs. It can also mean to invite in other contexts, but not here.

Examples:

• 请坐。 — Please sit.
• 请进。 — Please come in.

Here, it softens what is basically a command.

Why does 在窗口 come before 提交申请材料?

Because in Mandarin, location phrases often come before the verb.

Structure here:

• 请 — please
• 在窗口 — at the window/counter
• 提交 — submit
• 申请材料 — application materials

So the pattern is:

请 + 在 + place + verb + object

This is very common in Chinese.

Compare:

• 请在这里等。 — Please wait here.
• 请在前台登记。 — Please register at the front desk.

English often puts place information later, but Chinese often puts it before the main action.
