Visitors from Visa Waiver Program countries need an approved ESTA before travelling. Everyone else needs a B-1 business visitor visa, which covers attending conferences. Visa interview wait times vary widely by country, so apply as soon as your registration or paper acceptance is confirmed and keep the organiser's invitation letter with your application. Check travel.state.gov for the current rules.
Best time to go: Conferences run all year, with peaks in spring (March–June) and autumn (September–November).
Visa rules change often. Always confirm the latest requirements on the official government website before you book.
Citizens of Visa Waiver Program countries can attend with an approved ESTA for stays of up to 90 days. Other visitors need a B-1 business visitor visa. An invitation or acceptance letter from the organiser supports your application but does not guarantee approval.
