International attendees travel to the United States either on an ESTA authorisation under the Visa Waiver Program (citizens of the UK, Germany, France, Japan, Australia, South Korea and other VWP countries; USD 21, online approval usually within about 72 hours) or on a US B-1 business visitor visa (USD 185 consular fee, with interview appointment lead times of 8–12 weeks at many posts). Canadian citizens generally enter visa-free for business visits of up to six months with a valid passport. ATA Carnets are accepted for exhibiting machinery and equipment, and passports should be valid for the full stay plus any onward travel.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Valid for two years or until passport expiry; apply through the official CBP portal and carry the approval reference on arrival. Requires a consular interview with supporting invitation or registration documentation; B-1 status permits attending shows and meetings but not paid employment in the US.
