LOL; well, to be honest, I don't know how legitimate the 'Eligibility' part is. It was just a discussion I saw on a thread once, debating when Eligibility is completed since there appear to be multiple steps to it (GCMS notes reveal that eligibility is 'recommended passed' before it's actually 'passed'), so the theory was that the RECOMMENDATION is done prior to NA2, right after Completeness and Criminality are done, then NA2 is when the file is in transit to the local visa office, and then the eligibility recommendation is reviewed and either accepted or refused once the file gets to the local visa office, and processing is resumed, right before the Security check begins.
But hey, whatever we need to believe to keep the hope alive, right?
