I dont think all the files are being transfered, They are transferring certain files of certain NOC like 0121 . Really cant make out what the criteria is.
But my analysis of the forum posts earlier, shows that the files which are more complete in all respect and which are straight forward are being transfered to WVO..
Warsaw will depend on third parties/agents for verification( Back Ground Checks) of employment and Bank accounts etc..
since you have got your PER in Feb, if your file is transfered to WVO you will soon get a AOR. If its NDVO no AOR but MR or Interview. Wish you Good Luck.
