I think it just depends on the officer. Sometimes, they process eligibility right away along with the sponsorship eligibility. Sometimes they process it towards the end.. If anyone's eligibility is passed sooner or they receive a pre-arrival letter, then most of the time they are in the fast processing queue and will receive PPR/portal sooner.. Most of the time, after eligibility is passed, it goes for a security check, which is the last step before final approval..
