New York questions, answered from official sources

Forty questions about visiting, working and doing business in New York. Each page gives the short answer first, then how it works in practice, then what it is most often confused with, and links the official source so you can check the current rule yourself.

Travel and visit

Airports, the subway, OMNY fares and the weather by season.

Business and finance

Company formation, EIN, sales tax and employer duties.

Legal, visa and entry

ESTA, visas, work rights, border checks and customs.

Big city topics

Renting, schools, healthcare, waste rules and safety.

These pages explain how the rules work and link the authority that owns them. They are not legal, tax or immigration advice, and amounts and thresholds change, so open the source before you act.
