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 a 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 (visa category B-1), for tourism (visa category B-2), or for a combination of both purposes (B-1/B-2).

Visa Waiver Program
The Visa Waiver Program (VWP) enables most citizens or nationals of participating countries* to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. Travellers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel and meet all requirements explained below. If you prefer to have a visa in your passport, you may still apply for a visitor (B) visa.

Travel Without a Visa
U.S. visa policy permits citizens of certain countries to travel to the United States without a visa, when they meet certain requirements, under U.S. laws. For information about travel without a visa, click on the links below.
