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.
What is a Visa?
A citizen of a foreign country who seeks to enter the United States generally must first obtain a U.S. visa, which is placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship.
Certain international travelers may be eligible to travel to the United States without a visa if they meet the requirements for visa-free travel. The Visa section of this website is about U.S. visas for foreign citizens to travel to the United States.
(Note: U.S. citizens do not need a U.S. visa for travel, but when planning travel abroad may need a visa issued by the embassy of the country they wish to visit.)
