I'm sorry. When it comes to legal, this is what the lawyers get, this is what immigration consultants get, and this is what every MP's office is getting right now. It says very distinctly “or until a decision is made on your application, whichever is first”, and the timeline is always less than eight years.
If this is incorrect, your department has been sending out hundreds and hundreds of letters in the mail. There are 60,000 Hong Kongers here through this pathway program. Are you saying they're all getting a wrong letter?
