Ireland doesn't give free immigrant housing. They have processing centers where you can stay while your application is being processed. They are very bare bones accommodations and you only stay there for up to 14 days.
Please don't kid around, we know exactly how the government facilitates the migrations. If it weren't a biggie, why are there protests happening on the streets of Dublin?
Where do they live after the 14 days? Who pays their rent? I know in the UK private landlords are offered very favourable terms via SERCO, which would beat those they would get if they rented to individuals.
