WAC191925XXXX 状态更新 Case Was Transferred 希望有经验的各位解答一下！

USCIS 给我的case在上周五（7/19）邮件提示更新，上myuscis查了有了如下三条更新：

Case Transferred And New Office Has Jurisdiction
Case Was Received At My Local Office
Case Was Transferred And A New Office Has Jurisdiction

想问各位已经Approved 小伙伴，你们也都有经历过这一步吗。经历的话大概距离approval还有多久呢？

PS 看到地里有的小伙伴也是Non PP WAC191925号段的已经approved了，是不是通过号段来判断审批时间是不可靠的？真希望能省去STEM OPT的申请 :)

先感谢回答！
