8老师:
我是境外申请的绿卡，入境3个月了，还没收到，看来是寄丢了。
-Have you paid the immigrant fee yet? If no, they will not send you the plastic card. See:
https://www.uscis.gov/file-online/uscis-immigrant-fee
If you have paid the fee, you may contact USCIS to see what happened. You may visit the local USCIS Office if you want to and ask them for suggestion.
我担心的是，入境时给的移民签证是一年。如果一年内还没有顺利收到绿卡，我就要离境了吗？
-No. If you still can not get the card within one year, you may just go to the local USCIS Office to get the green card stamp on the passport for another one year.
