My case got approved and my employer got the email copy of the I797 and my case status was showing as Post decision activity but after 15 days of the decision the case status on the USCIS site is now showing as acceptance and the comments are as follows"an amended notice on this case was mailed describing how we will process your case. Please follow any instructions on the notice. This case is being processed at our VERMONT SERVICE CENTER location. If this I129 PETITION FOR A NONIMMIGRANT WORKER is still pending, you will be notified by mail when a decision is made, or if the office needs something from you." I have also recieved a notification email regarding the same. Did anybody experiance anything similar? please help me understand this situation.
