Traveling to the USA with a B-2 Tourist Visa or ESTA Travel Authorization
All international visitors to the United States must hold a valid visa or travel authorization (ESTA), unless they are green card holders. While visas are granted by U.S. embassies, the travel authorization can be easily obtained online. The Electronic System for Travel Authorization (ESTA) streamlines the application process for those under the U.S. Visa Waiver Program. For travelers arriving by air or sea, securing ESTA approval is a required step before beginning their journey to the USA.
