小白兔，我2007年6月7号打USCIS 1800 电话查询I-485. 接线员给我submit了一个query,说45天内我会收到信。结果出乎意料我和LD的I-485 8月8号一起批了，绿卡我们8月15号就收到了. 可是今天我们又收到移民局的那封45天的信,
We created a permanent resident card for you and mailed it on 08/13/2007 to the address we had on file at that time. you have notified us that you have not received it and the post office has not returned it to us. We must conclude that it has been lost in the mail. Therefore, you will need to file a Form I-90, application to replace permanent resident card.........
我们现在卡都拿到了，难道还得再交I-90换绿卡吗？我们现在收到的卡还管用吗？我们需不需要给移民局打电话说我们收到了？谢谢！！！
