Hate to crush your dreams but at the moment you have no chance of getting a job and won't for a long time considering you have no qualifications and especially since almost half a million irish people are currently unemployed! Also (nice) apartments are almost as expensive here as they are in new york, unless you are willing to share a dump with someone who probably doesn't speak english.. my advice is stay where you are for now, go to college, save up plenty of money and move in a couple of years when the economy is more stable.
Don't be ridiculous. Seriously. You haven't a clue.
Right now there are very few job opportunities for highly education Irish and EU nationals - what makes you think that being American is any sort of advantage? Quite the opposite, in fact. You're only 18, you have no real educational qualifications, you don't stand a snowball's chance in hell, dear.
It works this way: when an employer has an opening, he advertises it, and looks for potential candidates from suitably qualified local nationals. If he can't find any, he looks among suitably qualified EU nationals - and there are PLENTY of them. Only if he cannot find anyone suitably qualified from these criteria will he look to non-EU nationals.
At your end you'd need a job offer from a company registered with the Irish tax authorities, and they are not interested in people with no qualifications, and it's only when you have a job offer than you can apply for a residency/work permit from your country of origin. A job offer is no guarantee you'll get this red tape sorted, not by a long shot. Given that university or vocational education is now STANDARD in EU countries, you would be woefully under-eduated and under-qualified.
The only way you could move here would be to be independently wealthy and not have to work, or if you can get citizenship of any EU country (you'd have to be able to prove a parent or grandparent was born in one, not always easy to do), or you could stay where you are, get an education and some valuable skills, and try again in five years. Do not make the mistake of coming over here on a one-way ticket, you will be sent back. Do not attempt to marry an Irish person in order to acquire citizenship, it doesn't work that way.
You can stay in Ireland for up to 3 months provided you can prove you have enough money to support yourself during your stay, and show a return ticket. But until you have a real education, you can forget about living here.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
