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.

请问各位大侠，这是不是说已经批准了？不会是要补材料吧？谢谢。
