Travelers from many parts of the world can visit the United States without obtaining a traditional visa, thanks to the Visa Waiver Program (VWP). However, most foreign nationals still need a visa to enter the U.S. for tourism, business, study, or other purposes. Understanding who qualifies for visa-free entry and who must apply for a visa is essential before planning a trip.
The Visa Waiver Program allows citizens of select countries to travel to the United States for tourism or business purposes without a visa, for stays of up to 90 days. Instead of a visa, travelers must apply for Electronic System for Travel Authorization (ESTA) approval prior to boarding their flight.
Travelers from these countries still need to meet eligibility standards and should not overstay or violate the terms of their visit, or they may lose future VWP privileges.
Countries That Require a Visa to Enter the United States

Examples of countries that do require a visa include:
Applicants from these countries must plan well in advance, as wait times for visa appointments and processing can vary significantly depending on location and demand.
While the Visa Waiver Program provides a convenient route for many travelers, most of the world’s population still requires a visa to enter the United States. All travelers—whether visa-exempt or not—must meet entry requirements and may still be subject to inspection upon arrival. Understanding your country’s status and the applicable procedures is essential to ensuring a smooth and lawful entry into the U.S.
