Those guys will definitely want to keep you “working” by all means, of course, you know why, for many reasons, and you working is MORE advantageous to them. They don't want you to rely on their resources, and also, as you “work”, they collect taxes.
So, for the fellow whose application has gone past 24 months, deploy ALL means to keep calling and sending them GCMS notes, writing to your MP, and ensure to keep pointing it out that, your application is gone past the 24months period.
If it is the other way round, they keep insisting that “you are still within the processing time”. That PR is a great reprieve, even for one’s mental health. Press on them, it is your right. WP is not synonymous to PR.
