How great to hear about your interest in working in Ireland to do your internship! 😊
I'd encourage you to have a look at the official Tourism Ireland page
. You'll find useful contacts to the Dublin office.
Besides, the Learn International website
might be a useful source as well. They offer several programs which could interest you.
I'd also suggest you to visit the Ibec Global Graduates page
. They have internship programs in companies all over the world and they work with Tourism Ireland.
Good luck in your research!
