请大家帮忙看看RPI小M邮件的意思

说是要邮寄财产证明和PASSPORT就给发I-20，
A current bank statement dated within the last three (3) months and signed by a bank officer indicating an amount in U.S. dollars which exceeds $60,000 per academic year for the two-year duration of your program.

请问，这是不是就要6W D啊？   12W D现在拿不出来啊！！！

谢谢大家！
