The Consular Sections of the U.S. Mission in Brazil are responsible for providing visa services to those seeking to enter the United States.
Nonimmigrant visas are for international travelers temporarily visiting the United States. The visa allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security (DHS) Customs and Border Protection immigration officer to enter the United States. A visa does not guarantee entry.
International travelers visit the United States for a wide variety of reasons, including tourism, studies, business, medical treatment, and certain types of temporary work.
Advance planning can smooth the visa application process for you. Apply for your visa well in advance of your travel! Do not make non-refundable travel purchases until you have your visa in hand!
