Some students might have to get a student visa in order to come and study in Ireland. Regardless, all non EU/EEA and non Swiss citizens have to register on arrival with the GNIB
Please check on INIS Website to see if you require a visa.
Regardless, you will need to register in person with the Garda National Immigration Bureau (GNIB) once you arrive in Ireland. Citizens of the EU/EEA and Switzerland do not need to register with the GNIB.
Students who are nationals of visa-required countries should also note that Ireland is not a member of the Schengen Agreement. Therefore students who have obtained a visa for a Schengen country will need to apply for a separate visa for Ireland.
All students are advised to carry proof of acceptance to UCD in their hand luggage. Immigration authorities may ask to see it upon arrival in Ireland.
Your first point for visa information should be the Embassy with jurisdiction of your country or www.inis.gov.ie. However, should you encounter any problems with your visa application, please let the International Student Adviser, Carl Lusby, know as quickly as possible and she will advise you.
