Thats correct! Before 2022, priority date for nepal was always current . Which means if you adjust your status in jan 2021 you had chance to get GC by dec 2021 itself .

But now its mid 2024 and they are still processing for april 2022. It seems they will take another 2 years to clear 2022 , then they will start for 2023 in 2027 , they will likely finish processing for 2023 by 2035 , then they will work for 2024 .

This has happened for indian , chinese filopino for ages niw for Nepal.?

I dunno what ti say?
