--------是这样的，我爸爸妈妈问过了！ :-)

帮我看看这个表的一部分：
I do further promise to provide him/her the minimum amount of U.S.$_________________ per year for her/his living expenses and tuition for each year of her/his academic studies at ****. Evidence of my financial resources in the form of a bank statement or employer’s statement accompanies this Affidavit of Support.

“Evidence of my financial resources in the form of a bank statement or employer’s statement ”------这是什么东东，是银行的statement吗？一般需不需要存一段时间的（我指在美国），因为为了省了我爸爸妈妈给我从中国开证明的麻烦，我们想借一部分钱，先开出一个证明再说，但是能不能今天借了存进去，明天就取出来还掉呢？

erduo，如果在美国办存款证明可能要好办一些。据说只要拿了钱到银行，银行就给开证明，日期就是开证明当天的日期，所以如果借钱的话，开了证明，第二天就可以还钱了。不象国内，存款证明上要列出所有存单的帐号和开户日，到期日，然后是三个月不能动这些钱。

我还是在国内中行办了的，因为我身份证在家，我妈妈全以我的名字存了钱在中行，所以就省了亲戚证明这一道  ：）

下面是我老公问他一个曾经办过国内中行资金证明的朋友所得到的回信。


Here is the format of "Certificate of deposit"
"We hereby certify that up to Jul,01,2002 Mrs. XXX has deposit accounts
with this bank as follows:
....
Bank of China
Authorized signature"
It is provided by Bank of China. It has Chinese translation above English one.(Line by line) The person in bank knows how to fill it. (They has certain forms and only print the money and name, at the end the person will sign on it.) In Chinese, it is "存款证明".
PS. I think that only US dollar account works.

You also need a certificate from your (or her) parents saying that they pledged to give money to her. I didn't have them now, you can downloaded it from 新东方. But your parents need to go to 公证处 to certify it also. In Chinese, it is "经济担保书" or something else. it depends on the translator in your hometown. Remember, it is just a certified letter from your parents. Their signature and the stamp (图章) of 公证处 are important. It is better not to use someone other than 直系亲属.
Since you are in US now, there might not be a problem.  

Only those two papers are crucial. It takes some time and fees to get
them.
