我前些天已经收到绿卡了，USCIS的状态从 Card Production 变到 Decision。 今天收到一封email，说我目前状态是Your Case Status: Card/ Document Production，
On January 3, 2012 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 at 1-800-375-5283.
This step applies to applications that result in an applicant receiving a card (such as a "green card") or other document (such as a naturalization certificate, employment authorization document, travel document, or advance parole). Applications will be in this step from the time the order to produce the card/document is given until the card/document is produced and mailed to the applicant. You can expect to receive your card/document within 30 days of the approval of your application.
If you do not receive your document, please contact our National Customer Service Center at 1-800-375-5283.
有点把我搞糊涂了，这封Email是什么意思？我指纹是10月份打的，绿卡上面有指纹的。而且照片也是打指纹的时候照的，应该都没什么问题。突然收到这封邮件，觉得很奇怪，请8老师和p老师解答，我需要做什么？
