I presently live in Durban SA. Determined to emigrate to ireland / northern ireland as my father was born there. I am an office manager/supervisor and work within local government sector. Can anyone tell me if they regret moving to ireland and what are the work opportunities like? I want to live in a place where it is "total country living" but would obviously need to work in a city. What is Belfast like and what would be the nearest place to live so the travelling wont be too hectic?
