关于资金证明，急！
拿到一个3/4奖，还需要一些资金证明。
学校的要求是：1.enclose an original,offcial letter(not just photocopy)from a bank for each sponsor listed as giving you funds.
              2.enclose an affidavit of support for each sponsor listed as giving you funds.each affidavit must (1)verify that the sponsor agree to provide the support indicateed for your first year of study and agrees to meet similar expenses in future years to enable you to complete your degree;(2)show the legal signature of the sponsor . each affidavit is to be an original official letter, not a photocopy.

关于1，是不是办存款证明就可以了，怎么换算成美元？
关于2，如果父母的存款，有没有必要公正关系呢?要不要公证处公正父母愿意资助我的学习费用的信。

1 我觉得就是办存款证明，银行可以给你换算吧。
2 我觉得需要，我当时就公正的关系和资助信。
