Yes. As soon as a student is even considering suspending /deferring or withdrawing they should seek the advice of a Student Engagement Advisor. These are big decisions with significant financial and academic implications and additional visa implications for International Students. It is important that students are aware of the implications and also that they have had the opportunity to explore available alternatives before making a decision.
Also, very often it is possible for advisors to help resolve the problems that might be making a student feel like suspending or withdrawing. Students should also be aware of the correct process for suspending or withdrawing as it can lead to problems later on if this is not followed properly. Students should not just stop attending and presume this means they have officially withdrawn or suspended.
