Most foreign nationals traveling to the United States for business purposes, including attending a trade show, require either a B-1 visa or, for citizens of Visa Waiver Program countries, an approved ESTA under the WB classification. The B-1 visa is for business visitors participating in commercial or professional activities, including attending a scientific, educational, professional, or business convention or conference. VWP travelers may enter the U.S. for business for a maximum of 90 days without a visa, provided they have an approved ESTA. and https://www.uscis.gov/working-in-the-united-states/temporary-visitors-for-business/b-1-temporary-business-visitor

Processing: Varies by U.S. Embassy or Consulate. Global median wait time for a nonimmigrant visa appointment is approximately 30 days, though waits exceed 12 months at some posts. A $750 optional expedited interview fee (pilot program July 1 – December 31, 2026) allows eligible applicants at select consular sections to secure an interview within 10 business days. and https://migrantimes.com
The B-1 visa is typically valid for up to 10 years with multiple entries, and each stay is generally limited to six months as determined by CBP at the port of entry. The standard MRV fee is $185. A $250 Visa Integrity Fee may also apply, bringing the total cost to approximately $435, though administrative delays mean full implementation may not yet be universal. The fee is paid when a visa is issued, cannot be waived or reduced, and may increase yearly with inflation. and https://manifestlaw.com
