The previous policy from 2022, where 99.99% of people have extended their period to 2024, applies to almost everyone except a few individuals who couldn't due to passport issues. Therefore, I believe that I do not need to ask her again.
BTW, since those people who got PGWP from 2022 for 18 months, 99.99% of them have their extension to 2024. IRCC has no reason to have extra guidance for those 0.01% of people.
In my opinion, the key question for an officer making a judgment
1) whether to grant another extension to those who have already had one, and
2) whether the deadline for the second extension depends on the current work PGWP or the three-year PGWP after graduation.
3) a patient officer who will carefully read your explanation letter. Alternatively, having a lawyer represent you might compel them to handle your explanation letter with patience.
In his specific case, he has an advantage because he does not need to explain 2). Both two sit in between the time frame.
For the rest of us, If you did a great job for 1) and 2) but, unfortunately, meet an inpatient officer who rejects you. Then, after reconsideration, go to the court, which is the place for fairness and justice.
Do not be afraid.
