给妈妈办绿卡，有几个问题想请教大侠：
第一次指纹没有过。9月25日去按了第二次之后就没有信息。请问有办法知道第二次指纹通过没有。打电话去客服中心，说更换地址（8月底）以后没有更新。
第二个问题是AP好像是批准了。妈妈想在年底回去处理一些事情，所以非常着急。如果拿AP回去会有问题吗？
-Fine. By the way, iIf her fingerprinting fails eventually, USCIS normally will require her to provide non-criminal record certificate (i.e. Police Clearance Report) from both China and US, so she had better prepare this kind of documents, just in case. It is very easy to get the Police Clarence in US (just get it from your local police department), so you do not need to get it now, but had better get the one from China in advance.
在次谢过大家。
