AP是否批了？

Application Type: I131, APPLICATION FOR USCIS TRAVEL DOCUMENT

Current Status: Document mailed to applicant.

On August 28, 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.

請問各位大俠，這是不是說已經批準了？不會是要補材料吧？謝謝。
