Irish citizens are entitled to land in Ireland. If you are a national of the European Union (EU), of one of the other EEA countries (Iceland, Liechtenstein and Norway) or of Switzerland you may be prevented from landing in Ireland only in very restricted circumstances. Nationals of other countries need permission to land. The rules about permission to land are the same whether or not you are required to have a visa in order to come to Ireland.
On 27 October 2011 the European Communities (Communication of Passenger Data) Regulations 2011 requesting airlines to provide Advance Passenger Information (API) transposed Council Directive 2004/82/EC of 29 April, 2004. This new measure which is aimed at improving border control and combating illegal immigration will be introduced before the end of 2011 and will apply to all inbound flights to Ireland from outside the EU.
If you are an EU/EEA or Swiss national, you may be refused permission to land in Ireland only if:
You do not have to register with the immigration authorities as EEA and Swiss nationals have specific rights to live and work in Ireland.
If you are a national of any other country, you must get permission to land when you arrive in Ireland. The immigration officer may refuse for any one of a number of reasons. For example, permission may be refused if the immigration officer has reason to believe that:
If you are refused permission to land you must be given the reasons in writing. You may be given permission to land but with conditions attached. For example, you may be allowed stay for a stated period only. If you wish to stay in Ireland for longer than this you must get permission to remain by registering with your local immigration office. In Dublin this is in the Garda National Immigration Bureau (GNIB), and outside Dublin it is the local garda district headquarters.
Contact your local garda district headquarters if you live outside of Dublin. Contact the Garda National Immigration Bureau if you live in Dublin.
