Visitor Visa
Overview
Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business. B-1 visas are required for conference attendees.
Application
Visa Waiver Program
The Visa Waiver Program (VWP) allows citizens of participating countries* to travel to the United States without a visa for stays of 90 days or less, when they meet all requirements explained below. Travelers must be eligible to use the VWP and have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel.
If you are eligible to travel on the VWP, but prefer to have a visa in your passport, you may still apply for a visitor (B) visa.
Visit the Visa Waiver Program website for complete information.
