The SMU Ambassadorial Corps (ASMU) was set up in August 2003 to offer exemplary SMU undergraduates the opportunity to hone their skills as external relations representatives of the university. These student Ambassadors engage external guests, such as foreign VIP delegates and prospective students, on their visits to SMU as well as at important school functions.

Besides hosting distinguished guests at SMU, the Ambassadors also work closely with the SMU administration in organising and managing university projects that reach out to the university's external stakeholders.

Recruitment for new Ambassadors involves a stringent interview process that takes place in the first half of each year.

ASMU currently has 54 sophomores to senior year student Ambassadors of various nationalities.
