Short-term courses are usually certificate programs, and it seems ineffective for international students. Students can always opt for long-term courses of 2 years or at least 1 year. Because in countries like Canada, students cannot obtain a Post Graduate Work Permit (PGWP) with an 8-month course. International students in Canada can obtain a PGWP by taking up an abroad study course of 1-year duration or more. Moreover, in Canada and the UK, as an international student, you can get stay-back options for the equivalent of or more than the duration of the study program. Hence, a long-term course is the best for international students.
