그런데 아무것도 받은것도 없구요.

Document production or Oath Ceremony

On November 19, 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 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, refugee travel documents 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.
