This is not sponsorship in the financial sense, but J1 sponsorship or legal sponsor represents a guarantee: The American consulates only accept the application for a J1 visa if a designated exchange organization vouches that an intern, trainee and host company in the USA have met all of the program requirements. Intrax as a sponsor is responsible for the execution of the program in accordance with US regulations. Not every exchange organization is a J1 visa sponsor. Exchange organizations must apply for this and are themselves regularly checked by the US Department of State.
