ESTA approval is boarding eligibility, not entry — the real gate is the US entry interview. Officers commonly ask your purpose, length of stay, lodging and return flight, and answers should match your ESTA. US medical costs are high, so travel insurance is essentially a must, and installing an eSIM before you fly gives you maps and translation on arrival.
