I don't know, I looked at the excel spreadsheet, and most of the applications (let's say October 21 - Apr 22 AR) that submitted ADR received PAL shortly afterwards, but NOT portal. If we assume that PAL doesn't mean a thing (I and some others received PAL before ADR), it makes me think that no one actually looked at their documents yet. Or the docs were reviewed, they received PAL, but there needs to be approval and review from someone of higher rank. I know this conclusion doesn't have a strong basis, there are exceptions, and maybe I am biased, but it's the only thing that I can conclude right now.
I would love to go home again until March/April, but I know that as soon as I travel home, I might receive a portal. It's so hard just to sit here, watching people with later AR dates receiving portals. I know I am one of the luckier ones compared to AR 2021 applicants, but it's so frustrating.
