暑研教授意图

教授的回信大体还是挺喜欢我的，但是说学校方面没有official的capacity，是什么意思啊。。。意思是我暑假个人也不能跟着这个教授做暑研了嘛。。。要邀请函可能也要不到的嘛。。。求高人指点。。多谢～“I have checked with the school administration, and unfortunately I don’t think it would be possible for you to come as a summer student in an official capacity. If you would like to visit xxx over the summer for personal interest for a few days, I would be happy to speak to you and to introduce you to my graduate students. ”
