邮件这么写的:I am now trying to process your I-20 and you are required to provide proof of your financial support for your first year of school at the estimated cost of $36,867.00 in liquid funds. This will need to be presented by a copy of an official bank statement or letter on bank letterhead stating in US Dollars that you have this money available to cover tuition, housing, food, books, etc. Official copies of all financial documents must be in English. You must also demonstrate the ability to pay all of the expenses for the length of your program however, these do not have to be in the form of liquid funds.  lease keep in mind that this is an ESTIMATED cost of attendance that is based on full time status of 9 credits per semester for 2 semesters. This amount will be higher if you take summer classes or more than 9 credits per semester.
