爸妈B1/B2签证现场通过后却被check

爸妈准备五月底来美国参加我的毕业典礼。他们4月10号在北京大使馆面签B1/B2，签证官现场表示通过并给了蓝条。但一周后在网上查询时签证状态显示refused，附加消息为：

A U.S. consular officer has adjudicated and refused your visa application. Please follow any instructions provided by the consular officer. If you were informed by the consular officer that your case was refused for administrative processing, your case will remain refused while undergoing such processing. You will receive another adjudication once such processing is complete. Please be advised that the processing time varies and that you will be contacted if additional information is needed. For more information, please visit TRAVEL.STATE.GOV or the website for the Embassy or Consulate at which you made your visa application.
For more information, please visit U.S. Embassy Beijing.

这是被拒了还是行政审查中？有朋友们碰到现场通过后来查询却显示refused的情况吗？

我丈母娘今天去签B2，也是参加毕业典礼，我还以为毕业典礼怎么都能给过的

这种情况不用担心，不是check.就和我们f1签证一样，过段时间就护照汇回来了，hh
