Dear Mr Haas!
My name is Kseniia T. and I am an international second year student of the "Business English" course at the "Highline College". I am sure you are aware that I have been being a diligent student since the beginning of my studying.
I am writing to request you to grant me a week off from 5th July to 11th July. Unfortunately, my father has had to go in hospital for a heart surgery and my family expect me to be in my home country. I realise that such situation is not normal for our college, but I very much hope, that given circumstances, you would be prepared to give me a permission to be absence for the week.
Also I am asking you to let me to pass the psychology exam after my returning. My tutor is Mr. Johnson and I have already arranged with him about the pushing of the examination date.
I look forward to hearing from you.
