.just some advice (if not too late already)
As a US citizen I would pick a big 3 Caribbean school over Ireland as the programs in the Caribbean are identical to the US med school system, and you do your last 2 years in the US doing clinicals. Makes sense.
6 Years in ireland vs
4 years on the beach and 2 at home.
You decide. I really don't understand why Americans bother with Irish unis....
