申请19fall MA in English Studies，昨天收到了这封邮件，
Thank you very much for your interest in the Masters of Arts in English Studies Programme at The University of Hong Kong for the Fall of 2019. We were impressed with your application and your strong interest in pursuing your studies with us, and the admissions committee would like to extend you an offer to our full-time programme. This is dependent on the verification of all of your documents and your final transcript, which are currently undergoing the vetting process.  An official letter will be sent in a few weeks from the Faculty, but I wanted to let you know sooner so that you can start to make your plans for next year.

In the meantime, if you can give us an indication of whether you would like to join the MA programme, I will preliminarily hold a spot for you. If you have any questions, please do not hesitate to contact me. We hope that you will choose to join us the next academic year and look forward to welcoming you to the School of English.
这是传说中的推研信吗？
有申请这个专业的小伙伴吗，想知道vetting process都审核什么材料啊，一般多久出最终结果啊
