Advice to all that haven't gotten this process over after the 1 year the only way for making your case appearing at the priority list is to have support from your politicial representative... if not you gonna hang there for really long.
It worth involving your MP representative at your case so he ask and make things "move" there in Mexico . Give him a call (or an email and timeline of your app) and show that you are concerned about how your application is done.
Calling to IRCC center is NOT an option , is a total waste of time. The time your app is outside Canada they have no idea what's going on on it most likely.
The only ones that talk directly to Mexico is the political line.
