我的４８５因为 revoked I140被拒 (递交４８５ １８０ 天后换了工作），申请ＭＴＲ 三个月后ＭＴＲ获得批准， Online case status 说是二月九号邮寄了批准notice， 到今天快两个星期了也没有收到。Ｒｅｊｅｃｔｅｄ ４８５ 也有如下 ｕｐｄａｔｅ：
Case status:
Post-Decision Activity
We reopened this I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS on February 9, 2010, and are now reviewing our earlier decision. We also mailed you a notice describing the next steps in the process. Please follow any instructions on this notice. Our review should be completed within 30 days. We will notify you by mail when we make a decision or if we need something from you.
可是到今天10天了也没有收到mailed notice。 怎么查？What should I expect with “review should be completed within 30 days”?
