Background: The graduate school in our university, which is a public university in the US, has a policy about international students and their original diplomas and transcripts, which may be written in a different language than English. It is clearly stated that all the new international graduate students should inform their previous universities outside the US to send their original diplomas and transcripts in a sealed envelope directly to the current university in the US. But, unfortunately, according to some problems between my origin country (which is the same as the origin country of my friend, cf. Problem section) and the US, that's not possible at all and it's an already known fact in all the US universities. As a result, people like me as an international student, just turn their original + translated diplomas and transcripts to the graduate school by themselves without sealed pocket. I did this exactly at the end of my first semester and the graduate school accepted it. I turned the original diplomas and transcripts as it is clearly stated in the graduate school email that if my diplomas and transcripts are not written in English, the original documents + translated ones should be turned at the end of first semester.
Problem: Recently, one of my friends (he is also an international student from my country), who is in the same program at the same university as me, did not turn his original documents + translated ones by himself to graduate school. He just copied all the documents by himself and bought an envelope from Walmart and put them together and just turned it to the university and surprisingly, our graduate school accepted it in its current form!
Question: Today, I am informed that I need to have my original documents for some other purposes related to US immigration services and I went to our graduate school to get them back because according to my friend's story it should not be a problem for graduate school to return the original documents to me and accept the copies. But, graduate school officer refused my request and when I gave an example about my friend that just turned the copy to them, they just stated his university may just send the copies and if that's the case we don't care! Their words clearly says that I was just a stupid guy that followed their written rule and turned my original documents to them! And now, they don't care and even said they may have discarded them! As a result, it seems they just believed that the $1 Walmart pocket came directly from my friend's university! I believe it's not fair because they applied the rules differently and it could seriously affect my future. So: Should I inform the graduate school about that fake pocket? I mean it seems that it's my last way to deal with graduate school but it really drives me crazy about their rules and how they think and how they deal with documents! In fact, my problem is without informing the graduate school about my friend's case I cannot convince the graduate school that their system does not work properly and they serve different people randomly without a unified approach.
Update: I talked to associate dean of graduate school today and it was a really nice meeting and he was really friendly and helpful. I believe I transferred my purpose to him successfully without mentioning my friend's name and he was promised to do some investigation and then hopefully he will return my original documents to me.
