What is a immigration ireland website?

I live in Brazil, south America, we have the large wish, to live as well as work in ireland, specifically in the pleasing DUBLIN or surrounding areas, though we do not know where can we get information, if Ireland have the open heart for immigrants, if the supervision has the legalization offer for newcomers
based upon their veteran skills as well as education. People contend for we try to get sponsorship for work in Ireland though we have no idea how as well as where we can find one, is someone knows where? If we know, please, discuss it me, we conclude so much.
