Study Visa permits in Canada for India students, Immigration news: In a major development, a report stated that the number of study permits, issued to Indian students by Canada, has fallen sharply, late last year, after New Delhi ejected Canadian diplomats who would process the permits. A top Canadian official told Reuters that fewer Indian students applied for the study visa permits in Canada due to a diplomatic dispute over the assasination of a Sikh separatist leader Hardeep Singh Nijjar.
