Travel Visas to the United States
Citizens in participating countries may travel to the United States for short visits for temporary business without a visa through the Visa Waiver Program. However, travel to the United States under the Visa Waiver Program requires ESTA approval. A list of participating countries and Instructions may be found here.
Citizens of non-participating foreign countries who wish to enter the United States must first obtain a visitor visa. A complete list of requirements for obtaining a visa can be found here
Obtaining a visa can be a time-consuming process. To avoid complications with travel to the meeting, begin planning your trip at least four months prior to your departure
