STEM OPT 245号段卡被退回了USCIS

05/18：Case was received
07/02: New card is being produced
07/07: Case Was Approved
07/23: Card Was Mailed To Me
07/24: Notice Was Returned To USCIS Because The Post Office Could Not Deliver It
08/10: Card Was Returned To USCIS

最新的状态是说：We mailed your card to the address you gave us, but the Post Office could not deliver it. The tracking number assigned is UNAVAILABLE.
我的地址一直都没有换过，也收到了receipt notice，所以应该不是地址的原因。猜测就是USCIS没有给我寄。
USCIS最近真的是在抽风。USPS都没有pick up，就说被退回了。e-request的网站还一直不能提交。只能打电话问客服了。

请问有相同情况的小伙伴吗？

这也太SB了。。。真是服了他们了。。。

这个事情拖了这么久，还没有解决。

更新一下：
08/25，终于把退回去的卡寄出来了
08/28，联系USCIS索要tracking number，网上一搜被告知USPS无法deliever，又要被退回USCIS。住在南加，邮件已经到了北好莱坞了，但是就是无法往我家地址送。照理说，我也用这个地址收到过USCIS寄来的receipt，应该没有问题才是啊。极其怀疑是USCIS在寄卡的时候把邮编写错了。现在已经申请更改地址，希望能早日拿到卡。

话说境内激活H1B，十月一号生效的话，还需要EAD卡吗？
