Most international visitors need a US B-1 business visitor visa to attend a convention or trade show; attendees from Visa Waiver Program countries can instead travel on an approved ESTA for stays of 90 days or less. Attending a business convention or conference is a recognised B-1 purpose.
Estimated cost: Approximate government fees: around USD 185 for a B-1 visa application and around USD 21 for an ESTA authorisation. Confirm current amounts on the official US travel and ESTA portals before paying.
Processing: B-1 interview appointment waits vary by consulate, so apply roughly 8-12 weeks before travel. ESTA applications are usually decided online, with applicants advised to apply well before departure rather than on the day of travel.
Permitted B-1 activities include attending a business convention or conference, business meetings and consultations, and negotiating contracts. The visa does not authorise employment in the United States, and travellers should carry show registration and employer documentation.
