I need help writing an email. I have been placed on suspension and asked for an override. The override has been accepted by the dean but I am now limited to register only 7 credits. However, I am sponsored student by the embassy and they give me finical guarantee every semester. This semester they refused to give a finical guarantee because they told me that i have to register at least 9 credits in order to have issued finical guarantee. I told them that I cannot register more than 7 credits so they suggested that I register one more class at another college. I want to ask politely the dean if it is possible to register one class at another college and I do not want to be subject to another future suspension.
