WORKING IN IRELAND
If you are a national of a country which is not a member of the European Economic Area (EEA) and you wish to work in Ireland, you will require authorisation to do so.
For most types of employment, a non-EEA national requires an Employment Permit. For full information on work permits please visit the website of the Department of Jobs, Enterprise and Innovation.
A visa-required national who has been issued with an Employment Permit can apply for an Employment visa through their local Irish Embassy or Consulate. You will find useful guidelines and details of requirements for Employment Visa applications here.
