Pjiang 请帮忙解读USCIS 来信 (EB2, PD:Feb, 2005, RD: June 2007)

在我用USCIS公布的方法给他们打电话查询我的485 case (EB2, PD:Feb, 2005, RD: June 2007) 后，收到如下来信：

The processing of your petition/application has been delayed. All petitions received by this Service are required to have routine security checks that are resulting in delays of adjudication of petitions/applications. We can give no definite indication of when they will be completed. We apologize for the delay

这难道是说我的 Name Check 还没有过吗？或是其他什么? 我能做点什么加速这个过程吗？实在是太慢了。

在我太太打了相同电话后，USCIS 回信：
Our records indicate that we recently made an appointment for you go to one of our application support centers for processing associated with this case. your case is currently suspense until you complete this process. A copy of the scheduling notice for your information will be mailed within 30-45 days. Please follow any instructions on that notice.

这是需要做fingerprint 吗？我是主申请人，我们就做过一次fingerprint. 难道这个notice 需要30-45 天才能收到？

有人有类似经历吗？先谢了！
