大家觉得这个英文和沟通水平在美国政府能混到哪一级别？

以下为引用： 

不管你是什么原因离开了原来的工作单位，不要说原来单位不好，不要过分指责原来的老板，不要贬低原来的同事，即使是不愉快离开了单位，回信仍然这样写。

XX到了新的单位就职上任，一切就绪，为了和以前单位的朋友保持联系，今天给以前单位那里的同事朋友发了个电子邮件，与网上朋友分享，以便共同进步提高。

Hi, this is XXX. 

As you may know that now I am working in US Department of XXX, oversee the budget and fiscal operations and systems for xxx organization. I am very excited of this great opportunity.

Nine years of as xxx manager with xxx government, xxx government is part of my life no matter where I am. I love xxx government, who offered me an opportunity to develop my career and raise my family.

At xxx government, I was lucky that I worked together with you all. As an immigrant from Mainland China, I have no relatives here in America, a beautiful country. I take my work place as part of my family, and I treat you as my brothers, my sisters and my friends. I will miss you all.

With best regards

No Worry
