I have seen it mentioned that being able to apply on line increased the numbers, anyway more and more people are applying so the line inevitably gets longer.
There was a lady on here whose spouse naturalised and has 20 siblings many are married with children, they have it planned how to cascade the process, now who knows how many will still be alive, will want to come, still be married, have children who have not aged out etc.
But however you dice it, will be a lot.
