Email Standards

Last updated 13-Mar-2018

Principal Designated School Officials (PDSOs) and Designated School Officials (DSOs) receive their Student and Exchange Visitor Information System (SEVIS) User ID and password instructions by email when first registering in SEVIS. The Department of Homeland Security (DHS) continues to use PDSO and DSO SEVIS email addresses to send important SEVIS updates.

P/DSOs also use SEVIS to store students’ and dependents’ email addresses. To make sure email addresses in SEVIS are correct, please follow these standards.

  • PDSOs and DSOs may not enter email addresses used by more than one person, for example, info@AVCcollege.edu
  • SEVIS will auto-correct emails with certain common email address errors: “@@”; “‘space’”; “.@”; “@.”; “‘comma’”; etc.
