Overview

The United States has one of the most complex visa systems in the world, with numerous visa categories for different purposes. For most visitors, the B1/B2 visitor visa or ESTA (for eligible countries) is the appropriate choice.

US visa applications require an in-person interview at a US Embassy or Consulate for most visa types. The process can be lengthy, with wait times varying significantly by location and time of year.

Unlike many countries, the US requires applicants to demonstrate "strong ties" to their home country to prove they will return after their visit. This is often the most challenging aspect of the application.
