Most international attendees need either a US B-1 (business visitor) visa or, if travelling from a Visa Waiver Program country, an approved ESTA. The B-1/B-2 MRV application fee is USD 185 per applicant, requires an interview at a US embassy/consulate, and appointment wait times can run from a few weeks to several months depending on the post — apply at least 3–4 months before the March 2027 show. ESTA costs USD 21, is valid for 2 years, allows up to 90 days per entry and should be filed no later than 72 hours before departure. Canadian citizens generally need only a valid passport (no visa for business visits), and Mexican citizens may use a B-1/B-2 visa. Carry a letter of invitation from your company or the organiser, proof of onward travel and proof of funds; equipment and display material shipped temporarily can be covered by an ATA Carnet (the USA accepts ATA Carnets for commercial samples and professional equipment).
Processing: Varies by nationality; apply several weeks before travel.
