Dear Mr. Black，
I have applied for admission to Harvard University. As I have no relatives in the United States and I have no enough money for the tuition. I must find a financial guarantor. You know, in applying for a student visa, an affidavit to support must be submitted from an individual who will assure this opportunity. It plays an important role for my chance to enter the Harvard University. Could you do me a favor to be my financial guarantor. If I really have the chance of coming to the U. S., I will undertake part-time employment to cover all the living expenses.
Please write to me soon.
Yours sincerely,
