我收到的485批准信和装绿卡的信封上都敲了一个章:return service requested.
这是什么意思？
-That means if this letter can not be received by the person (you)in the address, the post office/delivery service needs to return this letter back to the sender (USCIS), not forward it to another address.
收到绿卡之后还有什么后续的 paper work 吗?我需要寄什么回去吗？
谢谢先~
