Most visitors from Western Europe, the UK, Australia and New Zealand do not need a visa, just an ESTA (Electronic System for Travel Authorization) under the Visa Waiver Program. But a past trip or a second passport can quietly take that option off the table. Answer three questions and see where you stand. For the full process, read ESTA & Entry.
This is practical guidance, not legal advice, and it does not guarantee entry: a CBP officer at the border makes the final call every time. Program rules change; confirm on the official pages (esta.cbp.dhs.gov for ESTA, travel.state.gov for visas) before you book. Verified October 2026, including Romania's 2025 rescission from the program.
