There may be some confusion for other reasons, so an examiner does not know whether to approve the extension of status. In addition, it is possible that the file was lost or that a request for evidence was sent, but never made it to its intended receiver. At this point, you 'may' need an experienced immigration and visa attorney to intervene, where your application is pending more than 90 days past the time that it should have been decided by the regional processing center responsible. If not, then you may consider whether you want to somehow upgrade the petition to premium processing for the additional fee. However, it can prove challenging to get an answer at times. Good luck.

Dont worry about this. CIS changes A# pretty frequently and without providing a reason, and without it having any effect on pending petitions.
