Here is news flash. I got the ACS positive assessment before all these new changes. in fact I got the results in March. So ACS had assessed all my 6 years.
I lodged the EOI and the NSW SS. NSW informed me that they will be assessing my work experience as( 6-4=2) even though my ACS results does not say anything related to that. Now because of this I only have 2 years of work experience and I will have 0 points for it. So this clearly shows that the State sponsorship and the DIAC will follow the new rule even though you got the ACS results before the rule change.
