回复：请教8老师,皮老师和各位热心大侠，有关Sign-up for Case Updates

不好意思,问的这个问题很初级,但还是烦请老师指点

1,这个功能是用来用Email接收Case Status的吗？ Sign-up 以后是不是就可以比Online 和收信早一点知道Case的Updates 情况?

Click:

When signing up, you can choose email and/or cell phone.

2,I-485递交一个多月了,现在Sign Up还来得及吗? -never late. anytime.

一般Sign Up后多久生效？-immediately

3，是不是自己随便一个Email地址都行？-Yes. personal email, such as gmail, yahoomail, hotmail, etc. may be portable and better
