I sometimes wonder though if a new passport makes immigration look at what you've been doing the first time you enter with it and it's linked to your previous one? I don't really know, just a thought?
If theres no control, it will open up a 'Cash in hand' foreign jobs market with no registration of who's even working in any given place. That's one reason why i can't take these reports literally.
90 day reports aside, i don't think its going to be long before we see the first reports of arrests etc due to people taking these press releases and assuming its a free for all to do what they like. Something is telling me, this isnt as simplistic as is being made out.
I would guess the part of the process of attending an interview with appointed members of the BOI kills it there and then for most? That's if your application even gets that far.
