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.
See our Directory of Visa Categories on usvisas.state.gov to determine which visa category might be appropriate for your purpose of travel to the United States.
Please note that the United States Embassy in Mauritania does not process immigrant visas or diversity visas.
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 all about U.S. visas for foreign citizens to travel to the United States.
(Note: U.S. citizens don’t 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.).
