SeDé, it may also depend on what you are doing. If you are flying solo and working in Ireland on your own then you may eventually be required to get citizenship, that is if you work and establish a residence. As for the visa, that is cool that you don't need one. If you are working for someone in Norway and they send you to work in Ireland(still working under the company in Norway) you may not need anything at all except for possibly a passport. Sounds wierd to me, but that is just a logical guess.

Oh and one more thing, you won't be considered an illegal immigrant, that's a whole different matter I would think. Seems what you plan on doing is pretty legal.
