Dear Dr. Chen XXX
Subject: Invitation to Chen XXX to conduct research atthe XXX University as an Academic Visitor
I am pleased to invite you to spend 12 months at the XXX University as an Academic Visitor, during the time period from 20st August, 2020 to 19st August, 2021.
I understand you will be supported by a scholarship from the Chinese Scholarship Council(CSC) and the Zhejiang Ministry of Education(如果是省里和留学基金委的合作项目，需要提及说省教育部，否则不需要the Zhejiang Ministry of Education这句。). The funding covers the international airfare, living expenses and health insurance for a period of 12 months. I have communicated with you for several times and can attest that your English level satisfies our requirements for an Academic Visitor. You will conduct research in the area of applied cryptography, in which you have had significant experience already(说明自己是有研究经验的，让签证官知道你不是去玩的).
Your academic visit to the XXX University is intended to facilitate independent research as set out in your application.(必须强调独立性研究，让签证官彻底放心)The XXX University is one of the largest security group in the European, and has a leading research in several aspects of information security. You shall be provided the necessary support for carrying out the research including providing office space, materials supplies and access to our library and other research facilities. Moreover, there are no bench fees for the moment here at the University of London(这里是没有收bench fee，如果需要收这里要加上费用是多少).
Please note that academic visitors are not permitted to engage in work in the UK other than the academic activity for which they are admitted under the Immigration Rules(再次用法律条文强调，让签证官的心再次放心).
I look forward to your visit.
