我的I-485 在大约二十天前批准,但是没有收到绿卡。最近收到下面的email:
Current Status: Document mailed to applicant.
On July 2, 2007 we mailed the document to the address we have on file. You should receive the new document within 30 days. If you do not, or if you move before you get it, call customer service.
请问是不是绿卡已寄出还是需要补充材料?请好心人给个答复。 谢谢!
