English language

Hi, I'm born in Bulgaria , currently living in Chicago, I'm wondering is the English language spoken in Irland any different than American English spoken in USA (particularly Dublin) ?..
Does anyone know? Is it going to be a good idea to take a few classes?.
Thanks

Hello,
English is spoken in Ireland so you shouldn't have a problem except for the Irish brogue (accent).
I doubt taking a class would be beneficial.
Btw, I'm an American of Macedonian descent with one grandmother who is Bulgarian.
