Hi guys, is it mandatory to try for study visa via a consultant itself or we can do ourselves?

You can do it yourself. Most of the consultants told me I am not eligible and other BS, so I did it myself and got the visa approved within a week or so during 2021.

Actually, no need but expert guidance gives you an edge otherwise likely to struggle about precise docx checklist

Always best to choose a Regulated Canadian Immigration Consultant. DM me for help
