Directory of Visa Categories
The purpose of your intended travel and other facts will determine what type of visa is required under U.S. immigration law. As a visa applicant, you will need to establish that you meet all requirements to receive the category of visa for which you are applying. When you apply at a U.S embassy or consulate, a consular officer will determine based on laws, whether you are eligible to receive a visa, and if so, which visa category is appropriate.
