You need a visa for the USA
To live and work in the USA you need a visa or a green card. The usual routes are a job with an employer who sponsors the visa, study, family, or the green-card lottery (Diversity Visa) if Poland is on the list that year.
Just visiting? Since 2019 Poles can visit the USA without a visa, through ESTA, for up to 90 days. You can't work on such a visit.

Your checklist in Poland
- Your visa or green card approved.
- A valid passport.
- Documents in one folder: birth and marriage certificates, diplomas, driving licence.
- Money for the start: a deposit, the first rent and a few weeks of living costs. Deposit rules depend on the state.
- Health insurance: care in the USA is expensive, and most people get insurance through their employer.
- Set up Polish TV before you go, so it works from day one (how to watch Polish TV in the USA).
