Do grad schools need an official transcript from universities where I was an exchange student for only one semester? I am a European non-EU student that went on an Erasmus exchange for one semester in the UK during my third year. Now, two and a half years later, I am applying to grad schools in the US, and the official transcript in my home university lists the courses taken in my exchange.

However, I was wondering if I need an official transcript from the Erasmus university as well. Getting this would be a big problem, since they only give them in person, and I have no way of getting one. Is it enough that the courses I took on my exchange are listed on my home university transcript, or will I have to do the impossible and get one from the Erasmus university too?
This is likely to be specific to a particular graduate school, but I studied in the UK for a year during my US undergraduate education. The courses and grades were listed on my transcript. The graduate school that I applied to (and to which I was accepted) did not require a separate transcript from the UK university.
