Jacks,
I have an ex who went to graduate school in Moscow. Guess what American employers, private and public, thought of it? They thought it wasn't worth the paper her degree was printed on, that's what.
If you want to be employed in America, you need to attend a school that is accredited in America. Otherwise, you are throwing away cash by attending college in Ireland. If your goal is to be employed in Ireland, then godspeed, but the USN (and most gainful employment equivelant to your level of education in the U.S.) is not in your future.
