An Extraordinary Ability Visa (O-1) offers numerous benefits, such as the ability to work in the U.S. without restriction and often for any employer of your choice. Additionally, your spouse and unmarried children under 21 years of age are eligible for O-3 visas, so they can accompany you to the U.S. This visa category also has no specific cap or quota, which means you don't have to worry about annual limitations.
