No visa, inside the EU
Poland and Denmark are both in the EU, so you can live and work in Denmark without a visa or work permit. A valid ID card or passport is enough.
Important: if you stay longer than 3 months, apply to SIRI for an EU residence document, then register at your kommune: you get a CPR number and the yellow health card (sundhedskort).
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 3 months' rent), 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 Denmark).
