NIW, EB2, I-485 UPDATE.

各位大侠, 俺NIW, EB2 CASE, I-140 filed in June 2002, I-485 filed in September 2004.

苦等六年. 在我即将放弃, 准备回国高就时, 今晚收到一个I-485更新(UPDATE):

Current Status: Document mailed to applicant.

On June 12, 2008 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.

请问是何意? 难道批了? 请高人指点.
