Q: Ms. Li applied for a leave of 11 days from Sept 30, 2019 to Oct 10, 2019 for his vacation that she planned to spend in your country at her own expenses. は 英語 (アメリカ) で何と言いますか?
A: It is good.

one small mistake
you wrote for his vacation
correct: for her* vacation

I am not sure about the meaning: she planned to spend in your country at her own expense.

Does you mean she is paying all of her own expenses? such as airplane ticket, hotel, etc

Because everyone pays for their own expenses, you do not need to add this part.

Better to end the sentence after the word “vacation.”

Make new sentence: She planned to spend a lot of money in your country. (just an example)

I understand your english. It is very good but the sentence is a bit long. Good luck and ask more questions if you have any.
