The phishing attempt purports to be from the Office, uses sophisticated terminology, and cites compliance action, suspension or revocation notices, with a warning to immediately login to the sponsorship management system (SMS).

The emails provide a link which takes user(s) to a screen that mimics the SMS log in portal. They are then asked to provide their login credentials, which may then be captured to gain access to their SMS account, primarily used to apply for and assign certificates of sponsorship (CoS).
