@IcedPurple it is very difficult to get a british passport if you live in Ireland. I am the same as her.
I was born in England and then moved to Ireland as a child. I have an English father and an Irish mother. I have dual nationality and I am entitled to a British passport.
I tried to get a British passport while living in Ireland when I was 22, and it was absolutely impossible. They just asked for so many impossible things. Not only did they want proof of address for every stage of my life, they wanted letters from my doctor at every stage of my life to say that my doctor confirmed that I was living there.
I would have been registered with my family doctor in one area, but I went to college in a different area far away. So my doctor said that she couldn't confirm that I was there, because even though I was registered there, I never attended.
It was so impossible, and the passport process had so many other requests. I tried for six months to get a Uk passport, and then I gave up.
I applied for my Irish passport, and it just asked for my birth certificate, my parent's birth certificate, and my parent's marriage certificate. I got the Irish passport within three weeks.
Michaella Mccollul also said that she got the Irish passport, because it was so difficult yo get the UK one.
