No visa, inside the EU
Poland and Ireland are both in the EU, so you can live and work in Ireland without a visa or work permit. A valid ID card or passport is enough.
The key step: your PPS number. Without it you can't sort out tax or benefits. Apply online (MyWelfare) with your ID and proof of address.
Your checklist in Poland
- A valid ID card or passport.
- Documents in one folder: birth and marriage certificates, diplomas, work references, driving licence.
- Money for the start: a deposit (at most 1 month's rent) and rent in advance (also at most 1 month), the first rent and a few weeks of living costs.
- Tell your Polish bank you are moving and keep the app working, so you can pay bills at home.
- Set up Polish TV before you go, so it works from day one (how to watch Polish TV in Ireland).
