鬱悶，收到CIS關於I485查詢後回複信

一個月前打電話查詢I485的狀態，今天收到回信：

The processing of your case has been delayed. A check of our records establishes that your case is not yet for decision, as the required investigation into your background remains open. ...

看來我的name check還沒完。我是去年9月遞的485，如果現在name check還沒完，是不是意味著要等很長時間？ 鬱悶！
