没current的时候就收到RFE，当时还挺开心的，结果RRFE三个多月也没消息，SR也做了
，回复如下：
We have received your service request and researched the status of your case
. We have had to perform additional review and this has caused a delay in
processing time. Your case is currently with an adjudicating officer. You
should receive a decision or notice of further action within 60 days.
现在是不是只能等了？
