Could you please edit my letter? :
I am writing to ask you an extension for due date of university enrollment on 8th October. My visa appointment will be on 29th August, therefore, I wont be able to enrol on time. I was wondering if it is possible for you to send me an extension letter via email. Also, I was supposed to receive a letter, indicating that the LENC program is in English, and that my current TOEFL score, 517, is acceptable by the university, but I have not yet received it. I would appreciate it if you could send it before 29th August.
