发了邮件去问我的 ４８５ case, RFS.Regs@dhs.gov
回信倒是很快，但是没有实质内容。
第一次是：
We need to wait on the FBI check. Some checks take longer than others. When the checks clear the office where the case is pending will inform the applicant of the next step in the process that needs to be taken. In this case, the checks may be taking longer, so the applicant should wait until the checks clear. He should get back with you in 60 days.
我又追问到底 NC 开始了没有，什么时候发去的，收到下面的回复（其实基本上就是拒绝回答）
If applicant was fingerprinted by USCIS or advised by USCIS that FBI name check was required, USCIS promptly follows up with FBI for processing these cases. FBI then performs the necessary checks and provides the information to USCIS in due course, considering backlogs and individual cases which make take longer to process. Applicant should be assured that process is ongoing and when completed, USCIS will inform applicant how to proceed with processing the case. This is routine security processing.
