No visa, inside the EU
Poland and Germany are both in the EU, so you can live and work in Germany without a visa or work permit. A valid ID card or passport is enough.
The key step: register your address (Anmeldung) at the Bürgeramt within 2 weeks of moving in. Almost everything else depends on it: your tax number, bank account, contracts.
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' basic 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 Germany).
