I called CIS 1 min ago, the nice lady told me that it's possible that they may mess up the order when do the data type in, but each package will be stamped with the actual received date, when all the cases are in system, they will be processed in the order of the actual received date.
so it's NOT that MESSY like many people are complaining about later filers got receipt earlier.....
Let's hold and be patient, Wish all of us good luck and get the receipt sooner
