It's great to hear that you are interested in coming over to see Ireland beat New Zealand in the rugby! 😉
Visa requirements depend on the country of origin of your passport. The Citizens Information
website has some helpful information and link for you to look at. It also will depend if you have a short-term student visa or a long-term student visa for the UK
We would suggest that you have a look at the visa and passport
information on our website for links to the Irish Immigration service and also reach out to local Irish Embassy/Consulate
prior to visiting the Republic of Ireland.
We hope this helps!
