I know that it refers to the forms completion, but how are supporting documents different?Samoo2014 said:"If you do not sign and date, the application will be returned to you" I think it is regarding the main application not the supporting documents, however I agree with you that Ref letter should be dated for more credibility, but the point that she has received PER then rejection form VO, If the rejection came first it would be a chance for resend the App again, Thanks
As per the second part of your quote:
The PER letter states that:
However a final decision on your eligibility to be selected as a federal skilled worker will be made by a visa office.
They assessed her against MI again (as they always do) and were not able to award points based on ref. letter that is non-compliant with the standards.
As a results, selection decision was not in her favour and they sent NER and retained the application.
