H1B 2013 PP Applied in April, Got Approved email on April 16th. On receving 797 attorney figured out that it was processed as COS instead of NEW. Notified this to USCIS. On june 18th status again changed to acceptance and petition pending. It is written an amended notice is sent.
What does this mean ? Does the petition go through all the steps again ? Will USCIS send one more approval notice ? How much time does this normally take.
Thanks everybody for your help.
