回複：回複：您可以到Infopass去在中國護照上蓋個I-155的一年移民簽證圖章

謝謝！是不是一定要到Infopass去在中國護照上蓋個I-155的一年移民簽證圖章，入關時的章有用沒，我的護照簽證頁上有一行字：upon endorsement serves as temporary I-551 evidencing permanent residence for 1 year.
-The funtions of that stamp are equal to the physical green card. So, you can just leave US for China and come back, and nothing needed to do (not need to get another stamp).

就是不知道移民局為啥給我通知，但是沒給我愛人，她是主申請人，也不知道要我幹啥？
-Your spouse has got the physical green card, didn't she? If yes, there is nothing related to her.
