It's wonderful to hear that you want to find a career here on our island!
There are plenty of resources that may be of assistance to you, as well! For example, the Citizens Information Website
contains a full section of support for coming to live and work in the Republic of Ireland. For information on Northern Ireland, please have a look at the NIDirect
page for the relevant information.
In addition, if you need the most current and accurate Passport and Visa advice, I'd recommend directly contacting your local Irish Embassy or Consulate
prior to travelling to the Republic of Ireland, and your local British Embassy/High Commission
or Consular Office, should you wish to work in or visit Northern Ireland.
I sincerely hope this helps!
