How to end an email asking for permission from my boss in Chinese?
Consider 敬上

书信
古代用于书信结尾的敬语或谦词，表示对收信人的尊敬。现多见于日语。
用法：
......（正文）
xxx（写信人）
敬上

I've received many messages set-up this way. &quot;Thank you for your time&quot; or &quot;Thank you for your consideration&quot; are very English-isms, you're best just to go with the Chinese way to do things.
