英文的委托函怎么写的?

委 托 函

建设部人力资源开发中心：
我单位XXX同志因执行XXXX任务，将于X年X月X日前往XXX国家（地区），在外停留XX天，费用XX支付。因该同志的人事档案寄存贵中心，特委托办理相关外事手续。

（单位名称并盖章）
X年X月X日
英文格式和这个差不多。

SAMPLE EIP AUTHORIZATION LETTER

SENT ON SPONSOR'S LETTERHEAD

Note to corporate sponsor: While EIP sponsorship is required only for a minimum of one semester, your company may want to list multiple semesters in this letter to provide a longer-term commitment to the student. A purchase order is not required if your company prefers other methods of payment. In that case, please substitute alternative wording in the first sentence of the second paragraph. Thank you.
