I-485 status, what should I do next?

去年，我遞交了兩個I-140 (NIW and EB1A)， 兩個I-485,分別連接到他們對應的I-485上，結果兩個I140都批了，遲遲不見綠卡下來，詢問結果，結果如下：

“…This case was sent to a supervisor, but because of the VISA was not currently available, the case was sent back to the shelf.

LIN ######, priority date 1-26-07 E21

LIN *******, priority date 1-8-07, E21

According to the June VISA Bulletin 2008, the priority date for 2^nd preference Chinese is 4-1-04. It appears that a VISA is not currently available”

 

我的問題是：

1. 我的LIN *******, priority date 1-8-07,明明是EB1A，那麽說應該是

E11 An alien of extraordinary ability，　而不該是Ｅ２1， 對不？如果是這個問題導致的綠卡延誤， 那麽我應該跟誰聯係，讓他們更正錯誤？

2. 如果是因為有兩個兩個I140和兩個I485的問題導致的，我是否應該將基於NIW的485 撤下？

多謝多謝。
