郁闷，收到CIS关于I485查询后回复信

一个月前打电话查询I485的状态，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. ...

看来我的name check还没完。我是去年9月递的485，如果现在name check还没完，是不是意味着要等很长时间？ 郁闷！
