催签收到additional administrative processing 的意思

我再7月8 广州面试。 今天发表到GuangzhouNIVI@state.gov 催签，收到回复是：
We have checked the status of your case and it is undergoing additional administrative processing.  This processing cannot be waived, and the final decision on visa issuance can only take place after this processing is completed. Please keep in mind that the timeframe for processing given at the time of interview was a guideline and cases can take longer to process, as processing times may vary from individual to individual.

请问有人有收到类似回复吗？然后情况是怎样的？additional administrative processing 是不是意味着还会check很长时间？

谢谢
