12/03 filed application
12/06 received by USCIS
12/09 received the email and txt receipt notice.
01/17 card is being produced.
从来没有收到过纸质版的receipt notice.
因为上个月买了房子，这个月close,担心中途地址变更，就保险的写的地址是我上班的
地方的地址。不知道是不是因为这个原因导致没收到hard copy of notice.打电话给
USCIS，他们说他们寄了。
现在担心这个卡是否能够寄到。还有一个问题，假设之后我查到状态改称card is
mailed to me， 是否可以打电话问tracking number?
求建议！
