With my Bachelor of Science degree, I'm sure I'm a bit useful to the economy of any nation, but I am not sure Ireland as a nation absolutely needs my skills and therefore my visa application will probably be turned down (highly-skilled, highly-payed doesn't quite describe me, a computer animator). I have been applying to open positions with companies all over the island with no luck. I believe they may be timid about sponsoring a foreigner's visa application, as I imagine it's costly for them.
I am not sure I want to get married in order to gain all the perks of residency and working there, etc (I'm 25).
I am beginning to wonder, is it impossible for me as an American to simply move there and begin working? Is my only choice to apply to the National Universities of Ireland or some other schools in order to study for my Master's degree? I'd like to get my Magister Scientiæ but I wasn't sure how easy it would be in Ireland, what sort of tuition assistance would be available for me, and other important factors.
So these are the thoughts on my mind. Can anyone relate? Can't blame me, it's a beautiful country with millions of wonderful people living in it.

Thanks in advance!
