Once an application is submitted, your name and other biographic information are entered into a U.S. government database called the Student and Exchange Visitor Information System or SEVIS. After the DS-2019 is created, a school official will sign the DS-2019, and then email to the host department for pick-up. If an update or edit is necessary, a school official will make the edit through SEVIS, and a new DS-2019 is produced.
A DS-2019 is used by an Exchange Visitor to apply for a J-1 visa at a U.S. embassy or consulate abroad. The DS-2019 must be presented along with your J-1 visa to Customs and Border Protection upon arrival at a U.S. port-of-entry to request admission to the US in J-1 status..
