5月15收到移民局 “Notice mailed welcoming the new permanent resident”后，
还没收到卡， 6月4号又来了一份通知：
Application Type: I485 , APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS
Current Status: Approval notice sent.
On June 4, 2010, we mailed you a notice that we have approved this I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS. Please follow any instructions on the notice. If you move before you receive the notice, call customer service at 1-800-375-5283.
这是什么意思？ 是卡寄过来了，还是什么其他的原因。
现在卡还没收到。
