AP 三個多月了， LUD，急問這是啥意思？

Current Status: Document mailed to applicant.

On XXXX, 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.

If you have questions or concerns about your application or the case status results listed above, or if you have not received a decision from USCIS within the current processing time listed*, please contact USCIS Customer Service at [phone].


還有，如果當天得知AP批準， 當天離開美國， 還能用AP回來嗎？
