我母亲下月要去广州绿卡面试，按照他们的程序，准备面试的第一步是要在online注册。我父母因为国内不会用电脑，我在美国注册发现注册不了，不知道您有没有遇到这样的情况，麻烦给一个建议。
-I don't have the idea. People did it in US before. I don't know what happen in this days. You may ask someone who knows how to use the computer in China to help you.
另外，我母亲曾经在美国呆过几年，是否需要在美国也办一个police certificate- You had better prepare it just in case.
还有，NVC 接受的是一个早几年的无犯罪公证，但他们的指导程序说要至少二年新的无犯罪公证，这种情况我们需要重新办一个新的公证吗？
-Need to get the new one (updated one).
他们网页上的指导程序没有说情楚要不要带petitioner tax documents, 能不能也给一个建议？
-Not need tax documents now. They changed the rule recently.
非常感谢！
