因为485批了以后,电脑上的状态一直是pending,而且一直没有收到绿卡,前几天给USCIS的客服打电话,说明情况,今天收到他们寄过来的信了,上面写着
type of service requested:non-delivery of permanent resident card
the status of this service request is:
we are unable to give you information at this time your file is currently at National Record Center. You will be notified by mail upon its arrival.
请问皮匠,National Record Center是什么地方,我的case怎么会在哪里呢? 还有,这句话到底是什么意思,是不是说他们对于我的请求无能为力,因为查不到我的case的具体情况?
我到底该怎么做呢?谢谢回答
