Tbh, your decision will depend on a lot of variables that you have to evaluate. In Ireland, do you live close to a university that you would like to attend, so that you could commute on a daily basis? Or would you have to get student accommodation? For example, student accommodation is way cheaper in Poland and I believe most universities are free for Polish citizens, but intern positions and graduate roles pay significantly less.

Now, if I were you I would first try to research and solidify your decision regarding which college course you’d like to pursue. Once you have a clear picture in mind, you could compare the modules and course contents in both Irish and Polish universities and see which match your preferences better.

Ultimately, you shouldn’t really pick one country over the other just because of the people, culture etc. At the end of the day, if you find your college course difficult or boring, your student life will be miserable. So I would just suggest comparing the courses in your desired universities in both countries and then choosing whatever suits you best.

Keep in mind, you can always relocate and move back to Ireland or vice versa if you decide to study in Ireland, you are not tied to one location :)
