Problem
In one of the research internship programs I am applying for in Japan, the institution requires me to directly upload recommendation and, otherwise the application will not be reviewed. However, I think this is not quite appropriate since generally applicants should not know the contents of the recommendation. I contacted the admission administrators to discuss other options but they said it was that institution's policy.
Now I am wondering if I could ask for the professor's recommendation. Even though I think he will understand the situation and there are examples that the professor voluntarily send students a copy of recommendation (i.e. the students receive the letter passively), I feel actively asking for the copy truly unprofessional and may make myself look bad in professor's eyes. This matters since he will provide recommendations to other institutions, where they follow the convention and accept recommendation through direct email with the professor.
Do anyone else have similar experiences and how do you do with that? Thank you in advance.
