Hello, What nationality would you say I am? I was born in the UK to an Irish Mother and English Father. I have an Irish Passport not an English one. I speak Irish as a first language then english. I speak with an English accent however i do sound irish when speaking sometimes. In a legal sense i am an Irish Citizen not English but in social terms
I'm in a similar situation.
My parents are both Irish (dad from Wicklow, mum from Dublin) but moved to England in the 80's because of the job shortage, then I was born in England. I have an Irish passport and have visited at least 3 times a year since I was born, I think I have dual citizenship but I have an English accent and I'm pretty ingrained in English culture.
If anyone asks I'm British but I always mention I have Irish heritage. On forms if there's a "White - British/Irish" box I tick it, if there isn't I'm just "White - British"
Your ethnicity (cultural background) is Irish
Your nationality (passport) is Irish
You are Irish
However, given that you probably have an Sassenach accent many in Ireland would consider you to be English..
